SACE Isomax S. 

The greatest project for moulded-case circuit-breakers 

A single series for all applications 

1 

SACE Isomax S is a project which evolves continually and is today the largest and 

most complete family of low voltage moulded-case circuit-breakers on the market, 

able to fulfil all installation requirements, from the small user up to large industrial 

electrical power distribution plants. 

Innovation, Technology and Quality have always been the main guides for ABB 

SACE in developing products and are at their peak in the SACE Isomax S series – 

the moulded-case circuit-breakers characterised by high quality, reliability, and 

performance under all conditions, simplicity of installation and safety of operation. 

The continual and constant evolution of the series has led to further extending the 

range of products, thereby making the SACE Isomax S offer increasingly complete 

over time. 

The series, which is divided rationally into eight basic sizes from S1 to S8, does, in 

fact, consist of different ranges destined to fulfil any installation need in a specific 

and optimal way. 

The completeness of the series can also 

be noted in better rationalisation of use: 

the overall dimensions, methods of 

installation and possibility of applying 

accessories are all the same, regardless 

of the type of range the circuit-breaker is 

placed in. 

Great importance is also put on the 

microprocessor-based electronic 

releases (mounted on the circuitbreakers 

starting from 160A): SACE 

PR211/P, PR212/P and SACE PR212/MP 

(International ABB SACE Patent), 

specifically designed to actuate dedicated 

functions for motor starting and 

protection. 

Thanks to innovative and state-of-the-art 

protection functions, they ensure 

reliability and precision and are unaffected 

by electromagnetic interference. 

A basic characteristic of these types of 

releases is their ability to communicate 

and dialogue with the SACE SD-View 810 

self-configuring software, thereby 

allowing full integration of the circuitbreakers 

in the management logics 

relative to electric network supervision 

and control systems.

The new series has 

been studied 

respecting the most 

modern ergonomic 

criteria. Witness to 

this is the prize 

awarded with the IF 

seal to the circuitbreakers 

at the 

Design Forum in 

Hannover.

A world of solutions for installation design 

engineering. 

An answer to all requirements. 

1 

The SACE Isomax S family is divided into eight basic sizes, S1, 

S2, S3, S4, S5, S6, S7 and S8 with rated uninterrupted currents 

from 125 to 3200A. 

The types of devices consist of: fixed, plug-in and withdrawable 

circuit-breakers with seven ultimate rated breaking capacity 

levels - from 16 to 200kA (380-415V) - identified by the 

letters: 

B, N, S, H, L, V, X. 

From this family, which is considered 

the common “nucleus”, 

a series of dedicated 

ranges are configured, which 

keep the same installation 

characteristics and accessory 

application possibilities. 

Within the series there are 

therefore circuit-breakers 

available for alternating and 

direct current distribution, current-limiting 

circuit-breakers, 

circuit-breakers for motor protection, 

switch-disconnectors, 

circuit-breakers for applications 

with voltages up to 1000V, 

and residual current circuitbreakers, 

as well as specific 

ranges (for motor protection 

and switch-disconnectors) 

complying with the North 

American UL489 and CSA 

C22.2 Standards. 

This means wider application 

possibilities both in industrial 

and civil sectors. 

They can therefore be mounted 

in primary (Power Center) and 

secondary (Panel Board) distribution 

switchboards, for motor 

protection and control (Motor 

Control Center), in generators 

and for end users. Their 

performances are, however, of 

particular interest where critical 

situations arise (very high 

rated and fault currents), or 

where complex plant engineering 

solutions are needed 

(special coordination requirements 

and plant automation). 

They also guarantee total selectivity 

of the protections up 

to full breaking capacity of the 

circuit-breaker installed on the 

load side. 

Centralised supervision 

and control 

systems 

The reliability, 

efficiency and 

quality of a LV 

electrical power 

distribution service 

is considerably increased 

by constant 

supervision of users 

and all the parameters of the installation 

itself. The information regarding 

the installations is collected using microprocessor-based 

field components 

which can be mounted directly on board 

the apparatus, such as the SACE 

PR212/P release, or using the devices 

in the SACE SD family. Moreover, the 

use of the SACE SD-View 810 software 

allows a simple personal computer to 

be converted into a work station for 

supervising and controlling electrical 

power distribution plants. 

GSIS9072 

Alternating current 

GSIS9073 

GSIS9074 

V~ 

Circuit-breakers with thermomagnetic 

releases and circuit-breakers fitted with 

microprocessor-based SACE PR211/P, 

PR212/P releases are available for protection 

of alternating current networks. 

These feature an application field from 

10 to 3200A and a rated voltage of 690V. 

Apart from the more generic applications, 

they are particularly suited to protection 

of generators, capacitors, transformers 

and machine tools. 

Thanks to its special construction characteristics, 

this range of circuit-breakers 

combines normal Isomax safety 

characteristics with very high performances. 

The breaking technique used 

(double interruption per pole) and the 

special shape of the breaking parts, 

allow very high value short-circuit currents 

(200kA) to be tripped extremely 

rapidly, making these circuit-breakers 

ideal wherever protection close to the 

power supply source is needed. 

Direct current 

V– 

Pole connection in series allows applications 

in the most severe operating 

conditions and in any type of network 

(insulated, with earthed polarity, and with 

median point of the power supply 

earthed). The circuit-breakers for direct 

current with thermomagnetic releases 

are available for operating currents between 

10A and 800 A, with rated 

voltages up to 750 V, with 3 poles in 

series, and 250 and 500V, with two poles 

in series. 

The range for applications at 1000V in 

alternating current and direct current 

extends the use of the moulded-case 

circuit-breakers even further and is a 

good example of the continual evolution 

of the SACE Isomax S series. They 

are particularly suitable for installation 

in special ambients, such as mines, 

petrochemical plants and for electric 

traction. 

ABB SACE proposes various solutions, 

which allow type 2 coordinations to be 

made for switching and protecting motors, 

from 0.37kW to 355kW. 

It is possible to select either circuitbreakers 

suited just to protection 

against short-circuit, or circuit-breakers 

fitted with the new SACE PR212/MP 

electronic release, which is technologically 

advanced and has been specifically 

studied for motor protection. The 

latter integrates protection functions on

The switch-disconnectors are derived from 

the corresponding circuit-breakers, keeping 

the overall dimensions, versions and 

accessories unchanged. They guarantee 

operation and isolation in maximum safety 

and their release device can be activated 

either by the undervoltage release or by 

the shunt opening release. They can also 

be fitted with residual current releases, 

thereby constructing “pure” residualcurrent 

circuit-breakers.

SACE Isomax S 

according to UL/CSA 

Standards 

Thanks to a specific range of SACE Isomax S circuit-breakers complying 

with the UL489 and CSA22.2 Standards, there are also greater possibilities 

for those customers operating on markets subject to the specifications 

defined in the North American standards. The range consists of 

seven sizes with rated uninterrupted current from 100A to 2500A and 

breaking capacities, at 480 V AC, which can reach 100kA. 

Within the basic series, there are circuit-breakers with magnetic only 

releases (MCP - Motor Control Protection) for motor protection, and 

switches (Moulded-Case Switch - MCS) for use as isolators or switching 

devices for lines, busbars or plant parts.

A world of success 

The SACE Isomax S offer has been constantly renewed according to market 

requirements – and often even anticipating these – and is always to the fore from 

the technological viewpoint. Meanwhile, the quality and reliability have always 

remained at the maximum levels expected and the market has shown its appreciation 

of this. 

1 

Behind every reference lies a requirement 

fulfilled. It is facts which speak for 

SACE Isomax S. SACE Isomax S is a 

highly successful product of recognised 

quality, with many fields of 

application and it involves different 

sectors all over the world, with either 

standard or highly personalised 

products. There is nowhere electrical 

power is used where SACE Isomax S is 

not to be found: manufacturing industries, 

steelworks, refineries and 

chemical plants, drilling rigs, gas 

pipelines, water pipelines, hospitals, 

airports, trains, railway and underground 

railway stations, calculation 

centres, offices, congress centres, 

theatres, and skyscrapers, as well as 

the most prestigious buildings worldwide. 

ABB SACE has, moreover, acquired 

knowledge which is practically 

unsurpassed in application areas 

where the highest degree of safety is 

required, and this has qualified it as 

the world leader in various sectors. 

Thousands of ships of all types – 

cruise ships, container ships, bulk 

carriers, tankers, etc. – and flying the 

flags of all nations – are equipped with 

ABB SACE products, which are also 

widely used in railway traction and are 

the favourite product in the depths of 

mines. 

ABB SACE apparatus is also responsible 

for protection (sometimes also 

integrated with control functions) of 

plants of considerable economic and 

technological importance, constructed 

within the sphere of large infrastructure 

projects. Orders are processed 

which stand out both for their size 

(such as the pumping stations of gas 

pipelines thousands of kilometres 

long) and for their advanced context 

(astronomical observatories and 

international research centres). 

SACE Isomax S imposes itself on the 

markets worldwide. For example, 

apparatus has been supplied to some 

of the most important European and 

Middle Eastern electricity boards as 

well as to North American and Asian 

electrified transport companies.

Selection and design engineering tools, 

management flexibility, services and consultancy: 

an all-round offer 

1 

With the aim of guiding and facilitating selection of its products, ABB SACE 

ensures 360° support, both before and after the sale. For this purpose, to design 

and size electrical installations, it makes various work tools available, which 

facilitate calculations, ensure compliance of the installation with the Standards 

and reduce the risks of any errors. 

These are basically divided into calculation, design and estimate software, and 

manual tools. 

– D.O.C. (Design Optimization 

& Computation) is a system 

which allows correct sizing of 

industrial low voltage electrical 

installations, able to propose 

the most suitable design 

selections regarding cables, 

busbars and protection devices. 

It allows the design engineer 

to develop clear and 

complete design documentation 

rapidly, based on the calculation 

models provided by 

the most recent standards. 

– C.A.T. (Computer Aided 

Technical Selection) is both 

an electronic catalogue and 

a technical aid tool for selecting 

and applying accessories 

to each individual circuitbreaker. 

By means of a guided pathway, 

it is possible to select, 

configure and order the most 

suitable apparatus for your 

own installation requirements. 

The calculation methods and 

data indicated on the slide 

rules are taken from the CEI, 

IEC and NFC Standards in 

force and from installation 

practice. 

The Guide to low 

voltage installations 

is a brief 

collection of legal 

and technical 

regulations 

based on the 

current standards, 

regarding 

design, sizing 

and installation 

of an electrical 

plant. 

The guide takes into 

consideration the user 

plant from the electric 

power delivery point (MV/LV 

substation) in 1 st category 

systems. 

Four Slide rules of different 

colours, which make up the 

ABB Kits, allow rapid sizing 

calculations of the electrical 

installation. The following can 

be carried out: 

- Cable sizing and calculation 

of the short-circuit currents 

(yellow slide rule) 

- Checking the protections 

against direct contact and 

short-circuit of the cables 

(orange slide rule) 

- Selective and back-up coordination 

(green slide rule) 

- Sizing of motor lines and 

transformer outgoing feeders 

(blue slide rule) 

Immediate ordering 

and management flexibility 

Rapid ordering procedures 

have been provided for circuit-breakers 

in the SACE 

Isomax S series, and the configuration 

logic of the series 

enables efficient and flexible 

warehouse management. 

An order file can be generated 

compatible with the EDIFACT 

(Metel or ABB) standard, ready 

to be converted into EDI format 

and transmitted electronically. 

1/8 ABB SACE

Using EDI (Electronic Data Interchange) 

to send orders rationalises 

the logistics chain, 

thereby reducing transit times 

and the risk of errors. EDI 

transmission allows the order 

to be loaded automatically at 

ABB SACE so that the request 

is immediately sent to production, 

together with the 

order acknowledgement 

to the customer. 

The availability of 

standardised accessories 

for 

groups of circuit-breakers 

makes it possible 

to reduce 

the 

number kept 

in the warehouse 

and 

very short 

procurement 

times allow 

limited stocks 

to be kept as 

these can be 

rapidly replenished. 

Training: 

an indispensable tool 

for professionals 

By means of its technical training 

courses, ABB SACE is 

committed to putting its wealth 

of experience gained in over 

more than 60 years of operation 

at disposal. The courses 

are an opportunity for all operators 

in the sector to update 

their knowledge and compare 

notes, under the guidance of 

experts. Information and training 

have always been success 

factors for professional 

growth and development. 

Professional refresher training 

on both technical aspects and 

product developments, as well 

as on the standards and legislation, 

is essential, considering 

that these have such important 

implications for the 

safety of people and plants. 

The primary aim is to meet the 

information needs of professionals, 

especially by converting 

the technical-standard 

and legislative concepts into 

practical terms which can be 

applied directly to the various 

products and installations. 

“ABB SACE Service” 

Training courses are also provided 

for operators and maintenance 

personnel who work 

on ABB SACE apparatus and 

systems. For this purpose and 

to meet the need for evaluation 

and maintenance of existing 

electrical installations, 

the company has set up the 

“Service Division” within its 

own structure, which acts as 

a qualified interlocutor working 

in close collaboration with 

the managers/users of the 

plants, to carry out maintenance, 

repair and overhauling 

activities at ABB SACE and on 

the user’s premises. The division 

also offers a spare parts, 

assembly and commissioning 

service for its own switchboards.

Double insulation 

The double insulation technique consists of total separation 

between the power circuits and the auxiliary circuits and is a 

characteristic of all SACE Isomax S apparatus from size S3 up. 

The housing of each electrical accessory is completely segregated 

from the power circuit, thus avoiding all risk of contact 

with live parts, thereby increasing operator safety conditions 

during management and inspection of the installations. 

Moreover, the circuit-breaker has redundant insulation between 

the internal live parts, both regarding thickness of materials 

and the distances, which are greater than those required 

by the IEC Standards and are in accordance with American 

usage. 

Positive operation 

The operating lever always indicates the exact position of the 

circuit-breaker moving contacts, thereby guaranteeing safe and 

reliable indications (I = Closed; O = Open; yellow-green line = 

Open due to release trip). The circuit-breaker operating mechanism 

has free release, regardless of the pressure on the lever 

or the speed of operation. Release tripping automatically opens 

the moving contacts: to close them again, it is necessary to 

reset the operating mechanism by pushing the operating lever 

from the intermediate position to the lower limit of the open 

position. 

For plug-in or withdrawable circuit-breakers, the moving part 

can only be detached from the fixed part with the circuit-breaker 

open (moving contacts separate from the relative fixed contacts).

The complete range of releases means that the protection functions 

of the apparatus can be coordinated according to current-type, 

time-type, energy-type or residual-current selectivity 

chains. It is therefore possible to isolate only the areas affected 

by the fault, ensuring maximum service continuity. Circuit-breakers 

in category B are available from 400 A up. 

Possibility of inspection 

With the circuit-breaker out of service, it is possible to check 

the state of the internal parts and live components of the circuit-breaker 

directly. The arcing chambers and the fixed and 

moving contacts are accessible simply by removing the circuit-breaker 

cover. The operation, facilitated by the limited 

number of components, reduces maintenance times and ensures 

a higher degree of safety.

Distinctive features of the series 

GSIS9125 

GSIS9126 

2 

Isolation behaviour 

In the open position, the circuit-breaker guarantees isolation of 

the circuit in compliance with the IEC 60947-2 Standard. For 

plug-in or withdrawable version circuit-breakers, in the rackedout 

or withdrawn position, the power and auxiliary circuits are 

isolated, ensuring that no parts are live. Under these conditions 

and by means of special connectors, it is possible to 

carry out blank tests, operating the circuit-breaker in complete 

safety. The redundant insulation distances guarantee the absence 

of leakage currents and dielectric strength in the event 

of any overvoltages between the input and output. 

Racking-out with the door closed 

This system, starting from 160 A, allows the circuit-breaker to 

be racked in and out with the compartment door closed, increasing 

operator safety and allowing construction of internal 

arc proof low voltage switchboards. Racking out can only take 

place with the circuit-breaker open, using a special rackingout 

crank handle supplied with the withdrawable version circuit-breaker. 

GSIS9127 

GSIS9129 

Electromagnetic compatibility 

By using SACE PR211/P, PR212/P, PR212/MP microprocessorbased 

overcurrent releases and SACE RC210, RC211, RC212 

electronic residual-current releases, the absence of unwarranted 

trips is guaranteed even in the presence of interference 

caused by electronic equipment, atmospheric disturbance or 

discharges of electrical type. Furthermore, the apparatus does 

not generate interference with other electronic equipment in 

the vicinity of the installation. This is in compliance with the IEC 

60947-2 Appendix F, IEC 1000-4, EN 61000-4, EN 50081-1, EN 

50081-2, EN 50082-1, EN 50082-2 European Directive No. 89/ 

336 specifications regarding electromagnetic compatibility 

EMC. 

Tropicalisation 

The SACE Isomax S series of circuit-breakers and accessories 

comply with the strictest regulations for use in hot-humid-saline 

climates (in compliance with climatograph 8 of the IEC 

721-2-1 Standards), thanks to: 

– insulating cases made of fibreglass-reinforced synthetic resins; 

– anti-corrosion treatment on all main metal parts (C UNI 3564- 

65 environment); 

– Fe/Zn 12 galvanisation (UNI ISO 2081), protected by a conversion 

layer consisting mainly of chromates (UNI ISO 4520). 

2/6 ABB SACE

Installation positions 

The circuit-breaker can be installed in any position without any 

effect on its rated characteristics. In compliance with the IEC 

60947-2 Standards, SACE Isomax S circuit-breakers can be 

supplied through either top or bottom terminals, without jeopardising 

operation of the apparatus. 

They can be installed in switchboards, mounted directly on the 

base plate or on Din rails up to size S5. 

GSIS9131 GSIS9128 

Mounting on DIN rail up to 630 A 

The brackets for fixing onto standardised DIN EN 50022 rails 

for S1, S2 and DIN EN 50023 rails for S3, S4, S5 simplify assembly 

of the circuit-breakers up to 630 A in standard switchboards. 

This allows standardised supporting structures to be used and 

facilitates the stage for designing and constructing the switchboard 

metalwork structure.

Resistance to vibration 

Degrees of protection 

The circuit-breakers are unaffected by vibrations generated 

mechanically or due to electromagnetic effects, in compliance 

with the IEC 68-2-6 Standards and the strictest regulations of 

the major classification organisations: 

– RINA 

– DET Norske Veritas 

– Lloyd’s Register of Shipping 

– Germanischer Lloyd 

– Bureau Veritas. 

Different measures have been taken in SACE Isomax S circuitbreakers 

to achieve IP20 degree of protection for the fixed, 

plug-in and withdrawable version circuit-breaker, excluding 

the terminals, and IP30 for the front parts of the circuit-breakers 

installed in switchboards. 

The fixed parts are always provided with IP20 degree of protection. 

It is possible to achieve IP54 degree of protection in accordance 

with the IEC 60529 Standard with the circuit-breaker 

installed in a switchboard fitted with rotary handle operating 

mechanism transmission on the compartment door and the 

special insulation gaskets which can be ordered separately.

Operating temperature 

SACE Isomax S circuit-breakers can be used in ambient conditions 

where the temperature in the surrounding atmosphere 

varies between -25 °C and +70 °C and stored in ambients with 

temperatures between -40 °C and +70 °C. 

The circuit-breakers fitted with thermomagnetic overcurrent 

release have their thermal element set for a reference temperature 

of +40 °C. 

For temperatures between +40 °C and +70 °C, with the same 

setting, there is lowering of the thermal trip threshold due to 

the temperature-related behaviour of the bimetallic strip of the 

release itself. 

For temperatures lower than +40 °C, on the other hand, there 

is an increase in the thermal trip threshold as indicated in the 

table on page 5/39. 

The electronic microprocessor-based overcurrent releases 

do not undergo any variations in performance with changes in 

temperature but, in the case of temperatures higher than 40 

°C, the maximum setting of the protection against overloads 

(function L) must be reduced to take into consideration inertial 

phenomena that occur in the copper parts of the circuitbreaker 

through which the phase current passes (moving and 

fixed contacts, and connection terminals) which cause a decrease 

in the rated uninterrupted current as indicated in the 

table on page 5/34. 

The performances of the circuit-breaker cannot be guaranteed 

for temperatures above +70 °C. 

To ensure service continuity of the installations, careful thought 

must be given as to how to keep the temperature within acceptable 

levels for operation of all the various devices and not 

only the circuit-breakers. For example, forced ventilation in 

the switchboards and in the areas where they are installed 

may be necessary. 

2 

Altitude 

Up to an altitude of 2000 m SACE Isomax S circuit-breaker 

rated performances are unaffected. 

As the altitude increases, the atmospheric properties change 

in terms of composition, dielectric strength, cooling capacity 

and pressure. 

The circuit-breakers therefore undergo derating, which can 

basically be measured through the change in significant parameters 

such as the rated maximum operating voltage and 

the rated uninterrupted current.

General characteristics 

The SACE Isomax S series of moulded-case circuit-breakers conforming to the IEC 

60947-2 Standard, is divided into eight basic sizes, with rated uninterrupted currents 

from 125 to 3200 A and breaking capacities from 16 to 120 kA (380/415 V). 

Selection of the size allows the basic electrical characteristics to be identified simply 

and immediately, whereas selection of the overcurrent release depends on the 

type of application required.

Thermomagnetic releases 

SACE Isomax S1, S2, S3, S5, and S6 circuit-breakers can be 

fitted with thermomagnetic releases and are used for protection 

of alternating current networks with the S1, S2, and S3 

circuit-breakers (for applications from 10A to 250A) and in 

direct current with the S1, S2, S3, S5, and S6 circuit-breakers 

(from 10A to 800A). They allow protection against overloads 

using a thermal device (with fixed threshold for S1 and adjustable 

threshold for S2, S3, S5, and S6) carried out using the 

bimetallic strip technique, and protection against short-circuit 

using a magnetic device (with fixed threshold for S1, S2, and 

S3 and adjustable threshold for S5 and S6). 

The four-pole circuit-breakers are always fitted with the neutral 

protected by the release.

SACE Isomax S circuit-breakers for power 

distribution 

Electronic releases 

The SACE Isomax S4, S5, S6, S7 and S8 circuit-breakers for protection in alternating 

current can be fitted with SACE PR211/P or SACE PR212/P overcurrent releases, 

constructed using electronic microprocessor-based technology. This allows protection 

functions to be obtained which guarantee a high level of reliability and tripping 

precision and which are unaffected by the external ambient. The power supply 

needed for correct operation is supplied directly by the release current transformers, 

in the presence of a phase current higher than or equal to 18% of their rated current, 

even with a single phase supplied with voltage. There is only one adjustment for all 

the phases and the neutral and the release is simultaneous for all the circuit-breaker 

poles, with trip characteristics which are unaffected by the external ambient. The 

functions and settings of the release protections can be verified by means of the 

SACE TT1 and SACE PR010/T Test units. 

GSIS9060 

SACE PR211/P 

SACE PR212/P 

3 

The SACE PR211/P release (available 

from S4 to S7) provides protection functions 

against overload L and instantaneous 

short-circuit I, and is available in 

the versions with functions I and LI. 

The wide range of adjustments make this 

release particularly suitable in all distribution 

where tripping reliability and precision 

is required and where magnetic 

only protection is needed (from 1.5 to 

12 x In), using the SACE PR211/P version 

I release. 

The SACE PR212/P release (available 

from S4 to S8) provides protection functions 

against overload L, delayed shortcircuit 

S and instantaneous short-circuit 

I, and against earth fault G. It is available 

in the versions PR212/P with functions 

LSI and LSIG; both allow use of the 

PR010/K signalling unit, the PR212/D 

dialogue unit and the PR212/T actuator 

unit, which can be used either simultaneously 

or individually, except for the 

PR212/T actuator unit which is always 

supplied when the dialogue unit is required. 

It is particularly suitable in applications 

with selective coordination requirements, 

for earthing protection against the 

risk of fire and evolutionary faults, and 

for remote control and parametrisation, 

network supervision and centralised 

load management.

For four-pole circuit-breakers fitted with 

SACE PR212/P release (LSI-LSIG), protection 

of the neutral can be set to 50% 

or 100% of the phase protection setting 

(by means of dip-switches on the front 

of the release). 

For those with SACE PR211/P release (I- 

LI), protection of the neutral at 100% can 

be ordered by means of an additional 

code 1SDA037505R1. 

With three-pole and distributed neutral 

circuit-breakers, external toroids can be 

used by connecting these directly either 

to the SACE PR211/P release, or to the 

SACE PR212/P release. On request, it is 

possible to obtain full protection of the 

neutral with setting equal to 100% of the 

protection. 

The SACE PR211/P and SACE PR212/P 

microprocessor-based releases are 

self-supplied and ensure correct operation 

of the protection functions, even with 

only a single phase supplied with voltage, 

in the presence of a current higher 

than or equal to 18% of the rated phase 

value. 

The protection release consists of current 

transformers (three or four according 

to the circuit-breaker polarity), the 

SACE PR211/P or SACE PR212/P protection 

unit and an OS demagnetising 

opening solenoid which acts directly on 

the circuit-breaker operating mechanism 

group. 

The current transformers are housed 

inside the release box and supply the 

energy needed for correct operation of 

the protection and the signal required to 

determine the current. They are available 

with primary rated current as indicated 

in the table below. 

When the protection intervenes, the circuit-breaker 

opens by means of the 

opening solenoid (OS), which changes 

over a contact for signalling release 

tripped. Resetting the signal is of mechanical 

type and takes place with resetting 

of the circuit-breaker operating 

lever. 

It is possible to test the opening solenoid 

(OS) by means of the SACE TT1 

test device. A positive result of the test 

coincides with circuit-breaker opening. 

All the protection functions with relative 

trip times can be verified and tested using 

the SACE PR010/T accessory unit 

(only for PR212/P). 

In the versions with SACE PR212/P - LSI/ 

LSIG release, it is possible to set the 

adjustment parameters of the protection 

functions directly from the front (dipswitch 

positioned on MAN), or to set the 

parameters remotely (dip-switch positioned 

on ELT) thanks to the use of the 

SACE PR212/D dialogue units. 

In case of any anomalies in remote 

parametrisation, the protection automatically 

uses the set of parameters set 

manually on the front of the circuitbreaker. 

The PR010/K signalling or PR212/D dialogue 

units supply the PR212/P (24 VDC 

±20%) protection release continuously 

and this allows the adjustment parameters 

to be set even with the circuitbreaker 

open.

The function carried out by the current-limiting circuit-breakers is to “limit” the specific 

let-through energy to a maximum in the case of short-circuit, safeguarding the 

integrity of the circuits and of the apparatus located on the load side. 

The breaking system used, which foresees double interruption per pole, allows very 

high value short-circuits to be interrupted extremely rapidly. 

Moreover, the special shape of the interruptive parts allows the peak values of fault 

currents to be limited to figures considerably lower than those of the short-circuit 

current present at the point of installation. 

For the circuit-breakers on the load side, the rapidity of opening notably reduces 

exposure to the electrodynamic stresses which occur in the case of a fault.

Integration with the SACE Isomax S family

to 

For S3X, S4X and S6X, conversion from 

the fixed circuit-breaker into the moving 

part of plug-in or withdrawable circuit-breaker 

is carried out by means of 

special kits listed under the chapter entitled 

“Ordering codes” (for S2X 100, the 

kit is the same as the corresponding 

S2 B/N/S one). 

The fixed parts of current-limiting plugin 

or withdrawable version circuit-breakers 

can, on the other hand, be used either 

for the current-limiting circuit-breakers 

themselves or for the corresponding 

SACE S2 - S3 - S4 and S6 automatic circuit-breakers. 

GSIS9114 

GSIS9029 

With regard to accessories, too, the S2X 

100, S3X, S4X and S6X current-limiting 

circuit-breakers use the same accessories 

provided for the corresponding automatic 

circuit-breakers and also keep 

the same electrical characteristics.

current-limiting circuit-breakers keep 

the standardised depth of 103.5 mm, 

standardised widths of 105 mm (S3X- 

S4X) / 210mm (S6X) for the three-pole 

versions and 140 mm (S3X-S4X) / 

280mm (S6X) for the four-pole versions, 

identical drilled fixing holes for the plugin 

and withdrawable versions and identical 

drilled holes for the compartment 

door in all the versions and for all the 

accessories. 

Applications 

The current-limiting circuit-breakers are 

suitable for installation in all types of 

civil, industrial and service sector 

plants, as well as in electrical installations 

on board ships, in mines, on offshore 

oil rigs and, generally, wherever 

very high short-circuit currents can occur 

due to the high powers of the generators 

and transformers – up to 200 kA 

at 380/415 V AC, 180 kA at 440 V AC 

and 75kA at 690 V AC. 

The circuit-breakers can be placed 

near the power supply source both for 

general protection (plants, user groups 

and electrical lines) and for protection 

of electric machines (motors, generators, 

transformers, capacitor banks). 

They can also be inserted in plants 

where back-up protection is foreseen, 

which allows use on the load side of circuit-breakers 

with breaking capacity 

lower than the prospective short-circuit 

current at the point of installation. 

The breaking capacities of the SACE 

Isomax S current-limiting circuit-breakers 

have exceeded the best performances 

achieved by other apparatus of 

this type.

The increased contact opening

let-through energy value I 2 t and 

the peak current.

Magnetic and electronic overcurrent releases 

SACE Isomax S circuit-breakers for 

motor protection (protection against short-circuit) 

General characteristics IEC 60947-2 and IEC 60947-4-1 

Three-phase asynchronous motor starting, switching and protection 

are essential operations for its correct use. The traditional 

system used for this purpose has three different devices: 

a circuit-breaker for protection against short-circuit, a thermal 

relay for protection against overload and lack of or unbalanced 

phase, and a counter for the motor operations. Everything 

must necessarily take into account the problems which 

arise on start-up. 

In particular, different factors must be taken into account when 

selecting these devices, such as: 

- the motor power 

- the starting diagram 

- the type of motor: with cage rotor or with wound rotor 

- the fault current at the point of motor installation in the network. 

ABB SACE proposes a wide range of circuit-breakers, which 

by implementing the protection against short-circuit exclusively, 

are suitable for use inside protected starters of traditional type. 

The new SACE S2X 80, with fixed magnetic protection at 13 

times the rated service current, is an extremely compact circuit-breaker, 

which stands out for its exceptional performances 

in terms of breaking capacity and limitation of the specific letthrough 

energy. 

Extremely simple and rapid to install, it has the same possibility 

of mounting accessories and personalisation as the S2B/N/S 

circuit-breakers. It can be used in a vast range of start-ups, 

from 0.37kW to 37kW and from 400V-50kA up to 690V-50kA. 

SACE S3 N/H/L 160/250 circuit-breakers and the S3X 125/200 

current-limiting circuit-breaker are fitted with a magnetic only 

release adjustable from 4 to 12 times the rated service current. 

They cover coordinations from 37 to 132kW and allow 

optimal motor protection thanks to their great flexibility due to 

the wide setting range of the magnetic threshold. 

Finally, SACE S4 160/250, S5 400/630, S6 630/800, and S7 

1250/1600, with different N-S-H-L breaking capacity levels, 

like the current-limiting S4X and S6X, can be fitted with the

SACE Isomax S circuit-breakers for motor 

protection (integrated protection) 


SACE PR212/MP electronic microprocessor-based releases 

3 

SACE Isomax S4N-H-L 160/250, S5N-H-L 400, S6N-H-L 800, 

S7S-H 1250 and S4X 250, S6X 400/630 circuit-breakers are 

fitted with SACE PR212/MP electronic releases constructed 

using microprocessor-based electronic technology. This allows 

functions to be obtained which guarantee high trip precision, 

utmost reliability and insensitivity to variations in the external 

temperature. The SACE PR212/MP electronic release 

guarantees complete motor protection as is fully integrated on 

board the circuit-breaker; moreover, it is able to control contactor 

opening in the case of a fault (except for short-circuit), 

by means of the SACE PR212/CI contactor accessory operating 

mechanism unit. Furthermore, the PR010/T unit for testing 

the release and checking the protection functions, the PR010/K 

signalling unit and the PR212/D dialogue unit are available. 

The electronic microprocessor-based releases are self-supplied 

and consist of three current transformers, the SACE 

PR212/MP protection unit and an opening solenoid which acts 

directly on the circuit-breaker operating mechanism unit. The 

current transformers – housed inside the release box, supply 

the energy and the signal required for correct operation of the 

protection. 

The release is temperature-compensated and sensitive to lack 

of phase according to Table IV of the 60947-4-1 7.2.1.5.2 Standard.

3/30 ABB SACE

The SACE Isomax S range of mouldedcase 

circuit-breakers for motor protection 

is perfectly coordinated with the new 

ABB line of contactors. The latter, defined 

as A-Line, together with the line of 

overload thermal relays and SACE 

Isomax S moulded-case circuit-breakers, 

is the basis for the new generation 

of apparatus specially designed to guarantee 

a system of products which can 

be integrated according to the applications 

required. All this is done with the 

aim of not only continuously improving 

the products, but above all to provide 

designers, installers and end users with 

the best solutions in terms of performance 

and reliability, combined with simplicity 

of the system. 

In particular, SACE Isomax S circuitbreakers 

and the “A” series of contactors 

are an extraordinary solution in terms 

of compactness, since they share the 

same width and design characteristics, 

thereby saving space, assembly material, 

installation time and relative cabling 

operations. 

The circuit-breaker-contactor group enhances 

this characteristic even further 

with the SACE PR212/MP electronic 

overcurrent release, which allows construction 

of an extremely compact protected 

starter, implementing protection 

against overload in accordance with the 

IEC 60947-4-1 Standard. 

SACE Isomax S moulded-case circuit-breakers 

and the new A series 

contactors share the same 

width and depth and have been 

designed to construct a single 

compact unit

for motor protection (integrated protection) 


Protection functions and parametrisation of the SACE PR212/MP release 

Function L 

Protection against overload 

Function L protects the motor against undesired overloads according 

to the indications and classes defined in the IEC 60947-4-1 Standards. 

Protection is based on a pre-established thermal model (ABB SACE 

International Patent) which, by simulating the copper and iron 

overtemperatures inside the motor, allows precise safeguarding of 

the machine. The protection intervenes when the preset 

overtemperature is reached. The trip time is fixed by selecting the trip 

class defined in the above-mentioned Standards. 

The function is temperature-compensated and sensitive to phase 

missing/unbalance in accordance with the IEC 60947-4-1 Standard. 

In the case of auxiliary power supply, the thermal memory function is 

guaranteed, which allows the release to continue calculating the motor 

temperature even after an opening operation. 

Parametrisation of protection L 

l1 = 0,4 ... 1 x In with 0.01 x In steps 

where l1 is the rated service current of the circuit-breaker, which 

must be the same or higher than that of the motor to be protected (I1 

> Ie), and In is the rated current of the current transformers. 

t1 = 4 - 8 - 16 - 24 s 

where t1 is the trip at 7.2 x I1 cold, 

depending on the class selected 

Class 10A - 10 - 20 - 30 

are the motor starting classes which determine the trip times for 

overload according to the IEC 60947-4-1 4.7.3 Table II Standards. 

Release of the contactor: in normal operating mode 

Tolerances: in accordance with the IEC 60947-4-1 Standard. 

3 

Function R 

Protection against rotor block 

Function R protects the motor against any rotor block during operation. 

This protection is automatically disabled for the whole of the motor 

starting phase and is then re-activated. 

The protection already provides its function from low current increases 

(from 3 times the l1 service current of the circuit-breaker) and can 

also be disabled. 

Both the current level to be tripped and the trip time delay can be 

selected. 

The protection intervenes when at least one of the phase currents 

exceeds the preset value and remains above that threshold for the 

set t5 time. 

Function I 


This protection function intervenes in the case of a short-circuit between 

phases. It is sufficient for a single phase to exceed the set 

threshold to cause immediate opening of the circuit-breaker (the protection 

cannot be excluded). 

The trip current can be adjusted up to 13 times the rated current of the 

release, whereas the time is fixed. 

To prevent unwarranted trips during starting, the protection recognises 

whether the motor to be protected is in the starting phase or 

whether there is a short-circuit. This is to allow starting under completely 

safe conditions. 

Function U 

Protection against lack of and/or unbalance of a 

phase 

Function U can be used in those cases where particularly precise 

control is needed regarding lack of and/or unbalance of phase currents. 

This function can be excluded and intervenes if the effective 

value of one or two currents drops below the level of 0.4 of the l1 

current set with function L and remains there for more than 4 seconds. 

Parametrisation of protection R 

l5 = OFF - 3 - 4 - 5 - 6 - 7- 8 - 10 x l1 

where l5 is the current at which the rotor is considered to be blocked 

and l1 is the rated service current of the circuit-breaker selected for 

function L. 

t5 = 1 - 4 - 7 - 10 s 

where t5 is the preset time threshold above which the release trips. 


Tolerances: ± 10% of the trip thresholds 

± 20% of the trip times 

Parametrisation of protection I 

l3 = 6 - 7 - 8 - 9 - 10 - 11 - 12 - 13 x In 

where I3 is the instantaneous trip current for short-circuit and In is 

the rated current of the current transformers. 

To prevent unwarranted trips during the inrush phase of the motor, 

instantaneous tripping of protection I takes place at 1.5 x I3 (for I3 < 

9 x In), whereas for higher values (I3 > 9 x In) tripping takes place 

at 13.5 x In. 



Parametrisation of protection U 

On, (with I6 = 0.4 x l1 and t6 = 4 s). 

Off, in the Off position, the release remains sensitive to the lack of 

phase according to the IEC 60947-4-1 Standard, modifying the trip 

curves for protection L. 




3/32 ABB SACE

Parametrisation of the release 

By means of the microswitch located on the 

front, the release can be fitted for 

parametrisation: 

Man. (manual), thresholds and times are adjusted 

by using the microswitches on the front 

of the relay 

Elt. (electronic), thresholds and times are adjusted 

remotely by means of the SACE 

PR212/D dialogue unit. 

Operating methods 

Normal mode: in the case of a fault detected 

by functions L-R-U, contactor opening can be 

controlled by means of the accessory SACE 

PR212/CI module or directly, without the need 

for external modules, with an ABB contactor 

fitted with an electronic interface with the circuit-breaker. 

Heavy duty mode: the circuit-breaker opens 

for any type of L-R-I-U fault. 

Back-up protection 

The electronic release verifies whether the 

circuit-breaker or the contactor is effectively 

in the open or relay tripped position following 

an opening command. If this is not so, after a 

delay set to long or short time, the command 

for circuit-breaker opening is given again.

The switch-disconnectors derive from the corresponding circuit-breakers, 

of which they keep the same overall dimensions, 

versions, fixing systems and possibility of mounting accessories. 

They are characterised by a rated voltage of 690 V in alternating 

current and 750 V in direct current.

They can be used as general circuit-breakers in sub-switchboards, 

as switching and isolating parts for lines, busbars or 

groups of apparatus, or as bus-ties. They can be part of general 

isolation devices of groups of machines or units for motor 

switching and protection. 

Isolation 

The main function carried out by these circuit-breakers consists 

of isolating the circuit they are inserted in. 

Once open, the contacts are at a sufficient distance to prevent 

an arc striking, in accordance with the standard prescriptions 

relative to isolation behaviour. The position of the operating 

lever corresponds with certainty to that of the contacts (positive 

operation).

Protection 

Each switch-disconnector must be protected on the supply 

side by a coordinated device which safeguards it against shortcircuits. 

The coordination table at the side shows the SACE 

Isomax S circuit-breaker which can carry out the protection 

function for each switch-disconnector. These are always pieces 

of apparatus of a size corresponding to or lower than that of 

the switch-disconnector. 

Making capacity 

The making capacity, Icm, is of considerable importance, since 

a switch-disconnector must be able to withstand the dynamic, 

thermal and current stresses that can occur during closing 

without being destroyed, up to and including closing under 

short-circuit conditions.

Endurance in the closed position 

This identifies the capacity for maintaining the closed position 

for short-time overcurrents. It is an important parameter which 

qualifies the performances of these pieces of apparatus.

In the field of moulded-case circuit-breakers, complying with 

the UL489 and CSA22.2 standards, the SACE Isomax S offer is 

enriched by the following ranges: 

– circuit-breakers for power distribution (fitted with 

thermomagnetic or electronic releases) 

– circuit-breakers with magnetic only releases for motor protection 

(Motor Control Protection – MCP) 

– switch-disconnectors for use as isolators or switching devices 

for lines, busbars or parts of a plant circuit-breakers 

(Moulded Case Switch – MCS). 

The SACE Isomax S offer in compliance with UL/CSA Standards 

is completed with the introduction of three new sizes. There 

are therefore increasing possibilities for those customers who 

also operate on markets subject to the standards defined in the 

UL/CSA Standards, with a whole range of moulded-case circuit-breakers 

available, with rated currents which go from 100A 

to 2500A and breaking capacities, at 480 V AC, which can 

reach 100kA. 

Apart from lowering the range of rated currents, introduction of 

the S1 size allows all those applications typical of power subdistribution 

where a circuit-breaker characterised by limited 

dimensions, but guaranteeing great versatility of application of 

accessories and installation, is particularly convenient. 

They further increase the possibility of selection, thanks to the 

introduction of the new rating for S3, Iu=225A, with three levels 

of breaking capacity (N/H/L), up to service voltage values of 

Ue=480V AC and 500 V DC. 

Finally, the S8 circuit-breaker according to the UL/CSA Standard 

also allows completion towards higher rated currents. 

Isomax S8V 1600, 2000 and 2500 are suited to installation 

immediately to the load side of power supply sources of low 

voltage systems and can operate safely under the most severe 

service conditions required by modern installations. Their high 

performances, great flexibility in mounting accessories, simple 

coordination with the devices on the load side and the possibility 

of limiting the depth of the switchboards thanks to their compact 

overall dimensions, make Isomax S8 a particularly advantageous 

choice.

Connection terminals 

The basic version of the circuit-breaker is supplied with: 

– front terminals for SACE S3, S4, S5, S6, S7, and S8 circuitbreakers 

– front terminals for copper cables for SACE S1, and S2 circuit-breakers. 

Different types of terminals are available, which can be combined 

in different ways (upper of one type, lower of another 

type), allows the circuit-breaker to be connected to the plant 

in the most suitable way for installation requirements. 

The following distinctions can be made between: 

– front terminals which allow connection of cables or busbars 

by acting directly from the front of the circuit-breaker. 

– rear terminals which allow installation of the circuit-breakers 

in switchboards with rear access to both cable and 

busbar connections. 

Terminals for connection of busbars or cables terminated with 

cable terminals and terminals for direct connection of bare 

cable are available. 

The information needed to make the connections is summarised 

for each type of terminal on pages 4/8-9. Flat bars of 

different dimensions and composition are recommended for 

connection with busbars. Furthermore, the minimum depth 

the flat bar to be connected must have is also indicated, if it is 

of a different composition to the one recommended. The minimum 

and maximum cross-section of the cables which can be 

tightened in the terminals and the diameter of the terminal are 

indicated for connection with bare cables 

The torque values to be applied to the tightening screws of the 

terminals for cable and to the screws used for connecting the 

busbars to the flat bar terminals are given. 

The circuit-breakers can be ordered complete with the terminals 

required, mounted directly in the factory, or the terminals 

can be ordered individually in packs of 3 - 4 - 6 - 8 pieces. 

Codes for ordering circuit-breakers directly in the configuration 

with upper / lower terminals of the same type are available.

Insulating terminal covers 

The terminal covers are applied to the terminals of the circuitbreaker 

to prevent accidental contacts with live parts and 

thereby guarantee protection against indirect contacts. The 

following are available: 

– lower terminal covers, which guarantee IP40 degree of 

protection for fixed circuit-breakers with rear terminals and 

for moving parts of plug-in or withdrawable circuit-breakers. 

– upper terminal covers for fixed circuit-breakers with front 

terminals, front terminals for cables and rear terminals, which 

guarantee IP40 degree of protection. 

– terminal covers for fixed parts of plug-in or withdrawable 

circuit-breakers, guarantee IP40 degree of protection on the 

front with moving part connected. They are available in a 

single version. 

The degrees of protection indicated are valid for circuit-breakers 

installed in switchboards. 

Screws for sealing the terminal covers 

These are applied to the terminal covers of fixed circuit-breakers 

or to the moving parts of plug-in or withdrawable circuitbreakers. 

They prevent removal of the upper or lower terminal 

covers, and can be locked with wire and a lead seal.

Service releases 

The service releases, shunt opening and undervoltage releases, housed and fixed in a slot in the left part of the circuit-break er 

are always alternative to each other. The power supply is made by means of special connectors for sizes S3 to S7, whereas for 

S1-S2, it is made by means of free wires 0.6 m long or with plug-socket connectors which can be supplied on request. 

Assembly is carried out by pressure into the appropriate housing in the left part of the circuit-breaker. 

Shunt opening release 

This allows circuit-breaker opening by 

means of an electric command. Release 

operation is guaranteed for a voltage 

between 70% and 110% of the rated 

power supply voltage Un, both in AC and 

in DC. It is always fitted with an auxiliary 

limit contact.

Time-delayed undervoltage release 

The undervoltage release can be combined 

with an external electronic power 

supply time-delay device, which allows 

circuit-breaker opening to be delayed in 

the case of a power cut to the release 

itself, according to fixed time-delays of 

0.5-1-2-3 [s], so as to avoid unwarranted 

trips caused by temporary malfunctions. 

It is available for the SACE S3, S4, S5, 

S6, and S7 circuit-breakers with power 

supply voltages at 110-220 V (50-60 Hz) 

only coupled with an undervoltage release 

at 310 V DC. Different power supply 

voltages are possible for S8.

Electric signals 

These allow information relative to the circuit-breaker state of operation to be taken outside the circuit-breaker. 

Installation of these accessories is carried out directly from the front of the circuit-breaker in special slots, completely se gregated 

from the live parts, with increased operator safety. 

Auxiliary contacts 

4 

These carry out electrical signalling of the 

operating state of the circuit-breaker: 

– Open/closed: indicates the position of 

the circuit-breaker contacts. 

– Release trip: signals circuit-breaker 

opening because the overcurrent release 

has tripped (for an overload or 

short-circuit), the residual current, 

shunt opening or undervoltage release 

has tripped, or the emergency opening 

pushbutton of the motor operator 

or the test pushbutton has been 

pressed. Signalling is reset when the 

circuit-breaker is reset (recovery). 

For SACE S3, S4, S5, S6, and S7 circuitbreakers 

the auxiliary contacts of the circuit-breaker 

are also available in the 

gold-plated version for digital signals, 

also suitable for use with voltages Un <

Residual current releases 

All the circuit-breakers in the SACE Isomax S series are preset for combined assembly with residual current releases. In partic ular, 

the SACE S1, S2, and S3 circuit-breakers can be combined with residual current releases in the SACE RC210, RC211 or RC212 

series, in the version side by side or underneath the circuit-breaker. 

Apart from the protection against overloads and short-circuits typical of circuit-breakers, the residual current circuit-breake rs 

which are derived from them also guarantee protection against earth fault currents, thereby ensuring protection against the ris k 

of fire. The residual current releases can also be mounted on the SACE S2D and S3D switch-disconnectors. In that case, the 

derived apparatus is a “pure” residual-current circuit-breaker, which therefore guarantees only residual current protection an d 

not the protections typical of circuit-breakers. The “pure” residual-current circuit-breakers are only sensitive to the earth f ault 

current and are generally applied as main isolators in small distribution switchboards towards end users. 

The use of “pure” and “non-pure” residual-current circuit-breakers allows continuous monitoring of the state of insulation of t he 

installation, ensuring effective protection against the risk of fire and explosion and, in the case of devices with I n 

30mA, they 

guarantee protection of people against indirect and direct contacts to integrate the compulsory measures foreseen by the 

standards and by the accident prevention regulations. 

The residual-current releases are constructed in compliance with the following standards: 

– IEC 947-2 appendix B 

– IEC 255-3 and IEC 1000: for protection against unwarranted trips.

The SACE RC210/1 polarised residualcurrent 

release is available for four-pole 

SACE Isomax S1 circuit-breakers for assembly 

side by side on DIN 50022 rail. 

The release is constructed using polarised 

type technology and acts directly 

on the release operating mechanism of 

the circuit-breaker, by means of a small 

piston which passes through a pre-cut 

window on the side of the circuit-breaker. 

It is fitted with a test button for periodically

SACE RCQ switchboard residual-current relays 

The SACE Isomax S4, S5, S6, and S7 circuit-breakers 

can be combined with the 

SACE RCQ switchboard residual-current 

relay with separate toroid (to be installed 

externally on the line conductors) and 

satisfies requirements with trip thresholds 

up to 30 A and times up to 5 s or where 

the installation conditions are particularly 

restrictive, such as circuit-breakers 

already installed, limited space in the circuit-breaker 

compartment. 

Thanks to its wide setting range, the 

SACE RCQ switchboard residual-current 

relay is suitable for applications where a 

coordinated residual current protection 

system is to be constructed at the various 

distribution levels, from the main 

switchboard to the end user. It is particularly 

suitable where low sensitivity residual 

current protection is required, for 

example in partial (current-type) or total 

(time-type) selective chains, and for high 

sensitivity applications (with physiological 

sensitivity) to realise protection of 

people against direct contacts 

On a drop in the auxiliary power supply 

voltage, the opening command intervenes 

after a minimum time of 100 ms 

and after the time set plus 100 ms. 

The SACE RCQ relay is suitable for use 

in the presence of earth currents of alternating 

type only (AC Type), for alternating 

current and/or pushbutton with continuous 

components (Type A) and is suitable 

for carrying out residual current selectivity 

. 

The SACE RCQ relay is of the type with 

indirect action and acts on the release 

mechanism of the circuit-breaker by 

means of the circuit-breaker shunt opening 

release (to be ordered by the user) 

to be housed in the special slot made on 

the third pole of the circuit-breaker.

4 

The dialogue unit is a device which allows 

two-way communication from the 

circuit-breaker to the outside and vice 

versa. ABB SACE has built two distinct 

dialogue units able to support two different 

standard market protocols: SACE 

PR212/D-M (Modbus RTU protocol) and 

SACE PR212/D-L (LonTalk protocol by 

Echelon). Both units are housed in external 

modules, which can be installed on 

DIN rails, and can be used with the S4, 

S5, S6, and S7 circuit-breakers fitted with 

SACE PR212/P electronic release, both 

in the LSI and LSIG versions, or SACE 

PR212/MP release. They must be supplied 

with a stabilised voltage of 24 VDC 

(±20% with maximum ripple ±5%) and 

be earthed. Communication towards the 

outside is generally addressed to a supervision 

and control unit, which has the 

task of collecting and storing the information 

regarding the part of the plant 

controlled. 

In the case of an error in the serial communication 

due to a fault in the dialogue 

unit or lack of auxiliary power supply, the 

SACE PR212/P protection unit works according 

to the last parameters set and, 

in any case, in accordance with what 

has been set manually. The SACE PR212/ 

D-M and SACE PR212/D-L dialogue units 

are always fitted in combination with the 

SACE PR212/T actuator unit, which allows 

remote closing or opening operation 

of the circuit-breaker (Remote Control) 

by means of two digital outputs which 

can be disabled thanks to the dip-switch 

(LOC/REM) positioned on LOC. 

Information available 

– State of the circuit-breaker: open; 

closed; tripped 

– Installation alarms: pre-alarm L; tripped 

L-S-I-G-R-V-PTC 

– Measurements: currents; N° operations; 

N° trips 

– Reading and writing curves and trip 

thresholds: only manual reading 

(MAN), electronic reading and writing 

(ELT)

SACE PR212/T actuator unit 

The SACE PR212/T actuator unit allows 

circuit-breaker opening and closing by 

means of the motor operator mounted on 

the circuit-breaker. It is always supplied 

in combination with the SACE PR212/D 

dialogue unit. An auxiliary power supply 

with a stabilised voltage of 24 VDC 

(±20%, with maximum ripple - ±5%) and 

earthed is required for operation of the 

unit. 

The PR212/D dialogue unit sends the 

digital opening and closing commands, 

received from the supervision and control 

system, to the inputs of the SACE 

PR212/T actuator unit, which carries out 

circuit-breaker closing and opening by 

means of a power relay. The motor operator 

of the circuit-breaker (use the 

versions with power supply voltage at 

110 V AC/DC or 220 V AC) must be 

connected to these relays. 

GSIS9043 


This allows control of tripping of the SACE 

PR211/P, SACE PR212/P, and SACE 

PR212/MP electronic releases and the 

trip test of the opening solenoid OS. The 

device is supplied by means of a 12 V 

replaceable battery and is fitted with a 

two-pole polarised connector-tracer point 

housed on the bottom of the box, which 

allows connection of the device to the test 

input bushings located on the front of the 

SACE PR211/P, SACE PR212/P, or SACE 

PR212/MP releases. 

The limited dimensions of the accessory 

make it practically pocket-type. The trip 

test device can be used on the SACE 

Isomax S4, S5, S6, S7, and S8 circuitbreakers.

SACE PR212/K signalling unit 

The SACE PR212/K signalling unit, only 

available for S8, is able to convert the 

digital signals supplied by the SACE 

PR212/P - (LSIG) protection unit into electric 

signals by means of normally open 

electrical contacts. An auxiliary power 

supply is needed to operate the unit. It is 

connected to the internal bus of the protection 

unit by means of a dedicated serial 

line over which the information regarding 

the state of activation of the protection 

functions passes, on the basis of 

which the relative power contacts are 

closed to signal: 

– pre-alarm for protection function L 

(I>0.9 x I1) 

– protection function L, S, I, G trip 

– release trip 

– communication error with protection 

unit.

SACE PR010/K signalling unit 

The SACE PR010/K signalling unit can 

convert the signals received via the bus 

from the SACE PR212/P (LSI or LSIG) and 

SACE PR212/MP (LRIU) protection units 

into electric signals by means of normally 

open electrical power contacts. 

An auxiliary power supply with a voltage 

stabilised at 24V DC (±20% with maximum 

ripple - ±5%) and earthed is 

needed to operate the unit. 

It is connected to the Internal Bus of the 

protection unit by means of a dedicated 

serial line over which the information regarding 

the state of activation of the protection 

functions passes, on the basis of 

which the relative power contacts are 

closed. 

In particular, the following signals are 

available: 

Alarm signalling remains active for the 

whole duration of the overload up to any 

release trip. 

The protection trip signals remain active 

during the timing phase and remain 

that way even after release trip. 

A Reset pushbutton on the front of the 

unit allows the state of all signals to be 

reset. 

There are also two LEDs available on the 

unit for visually signalling the following 

information: 

– “Power ON”: auxiliary power supply 

present 

– “TX (Int Bus)”: flashing synchronised 

with the communication activity with 

the Internal Bus 

The table below shows the characteristics 

of the signalling relays available in 

the SACE PR010/K unit.

Use of the trip curves of circuit-breakers with 

SACE PR212/MP electronic release 

For correct parameter setting of the SACE PR212/MP electronic release, it may be useful to compare the overall circuit-breaker 

curve with the motor starting curve. 

For this purpose, with the protection function graphics shown on the following pages, it is possible to draw the overall curve 

required for the circuit-breaker fitted with SACE PR212/MP release simply and immediately. 

N.B. For function L, as for all the other functions, make sure you place a glossy tracing sheet over the curve so that the time s on 

the axis of the co-ordinates coincide. 

5 

• Function L (cannot be excluded) - 

Protection against overload 

To protect the motor against any overloads, as a first step it 

is necessary to adjust function L to a current I1 higher than 

or equal to the rated current of the motor Ie: I1 > Ie. 

For example, if Ie = 135 A, an S4H160 circuit-breaker can 

be selected with In = 160 A and the following adjustment 

carried out: I1 = 0.85 x In = 136 A. 

The second step is to select the trip class according to the 

motor starting time ta. For a motor with a start-up overload 

of 6 seconds, class 10 can be selected, with a trip time of 8s 

at 7.2 x I1. 

To trace the curve correctly on the glossy sheet, according 

to I/In, simply place the glossy sheet over the graph of 

function L so that I/In = 0.85 (on the glossy sheet) corresponds 

to I/I1 = 1 (on the graph) and draw the curve relative 

to class 10. 

• Function R (can be excluded) - 

Protection against rotor blockage 

Protection against rotor blockage can be set both with regard 

to the trip current I5 = 3 ... 10xI1 (in this case I5 = 3 ... 

10 x 0.85 x 160), and with regard to the trip time t5. 

To trace the curve correctly on the glossy sheet, simply 

place the glossy sheet over the graph of function R so that 

I/In = I1/In (on the glossy sheet) corresponds to I/I1 = 1 (on 

the graph). In this case I/In = I1/In = 0.85, and draw the 

desired curve. 

• Function I (cannot be excluded) - 


This protection function against short-circuit recognises 

whether the motor is in the starting phase, thereby avoiding 

unwarranted trips; the trip threshold can be set from 6 x In to 

13 x In. 


place the glossy sheet over the graph of function I so that 

I/In = 1 (on the glossy sheet) corresponds to I/In = 1 (on the 

graph) and draw the desired curve. 

• Function U (can be excluded) - 

Protection against loss and/or unbalance 

of a phase 

Protection against loss or unbalance of a phase, if set to 

ON, intervenes when one or two phases have a current 

lower than 0.4xI1 (0.4 x 0.85 x In = 0.4 x 0.85 x 160 A = 

54.4A in this case). 


place the glossy sheet over the graph of function U so that 

I/In = I1/In (on the glossy sheet) corresponds to I/I1 = 1 (on 

the graph). In this case I/In = I1/In = 0.85, and draw the 

desired curve.

Operation and protection of the low-voltage side 

of three-phase transformers 

In order to choose the SACE Isomax S circuit-breakers to install 

both on the transformer risers and on the lines branching 

downstream of them, reference can be made to the following 

table dealing with transformers with no-load voltage on the 

secondary equal to 400 V which is the most common condition 

of use. The table has been drawn up considering infinite power 

upstream and the most unfavourable case has been assumed, 

that is, that the short circuit occurs on the transformer clamps. 

As regards users, the short circuit is considered downstream 

of the user circuit-breaker clamps.

Notes 

1) The risk of a double fault to 

earth being sufficient for the fault 

current to affect only one side of 

the circuit breaking poles is 

considered negligible. 

2) For rated voltages greater 

than 750V the 1000 VDC range 

is required.

Using these the correction factors means that the tripping current 

values will be higher for the same tripping threshold, or, 

vice versa, that having identified the tripping value one needs 

to set the tripping threshold following the reclassified scale 

range. 

Example 

– Operating current: Ib = 600 A 

– Magnetic protection required: Im = 5000 A 

– Magnetic protection required 

to set: 

therefore in this specific case, having chosen circuit-breaker 

S6 R630 (ln = 630 A), the magnetic threshold setting value will 

be:

(*) these are the distances to be respected for circuit-breakers fitted 

with a flange for the compartment door or side conductor outlets. 

The distances between centres are for the installation of fixed 

and plug in circuit-breakers. When installing withdrawable 

SACE S3, S4, S5, S6, S7 circuit-breakers you should also take 

into account the dimensions of the metal supporting channel 

that needs to be fitted between the guides of the fixed parts of 

two adjacent circuit-breakers.

is only allowed when 

the release is energised (the closing 

lock is implemented mechanically).

is open and closes it again 

upon a manual closing command 

from the rotary handle, in conformity 

with the Standards governing

3) Electrical resetting always enabled 

The electrical opening control (contact SO2) is connected in series 

directly to relay KO for S3 - S4 - S5 or connected directly to 

pole A3 of connector X2 (for S6 - S7) and is therefore always 

enabled. 

Example of use: automatic resetting of the circuit-breaker immediately 

after the releases have been tripped 

N.B. If an overcurrent release is fitted, it will be necessary to 

identify the causes that brought it to its tripped position in order 

to prevent it from closing again in short-circuit conditions. 

Manual resetting is always allowed in each of these examples. 

Instructions for resetting the circuit-breaker after the releases 

have tripped 

The circuit-breaker can open both through the action of the motor 

operator and due to the following releases tripping: 

– overcurrent 

– undervoltage 

– opening 

with consequent opening of contact SY (if fitted) in series with relay 

KO. 

A reset operation involving manual or electric opening will have to be 

carried out in order to close the circuit-breaker again after tripping. 

Contact SY closes again at the end of the operation. The type of 

resetting should be chosen to suit the design requirements and duty 

conditions. A number of possible solutions are suggested below: 

External 

circuit 

Conn.X1 

Term.XV 

Internal 

circuit 

1) Manual resetting only 

The electrical opening control (contact SO1) must be connected 

in series with contact SY. Opening (for S3 - S4 - S5 using the 

auxiliary relay KO) is therefore prevented until the circuit-breaker 

is in its tripped position. To reset the circuit-breaker one needs to 

operate the related lever until the circuit-breaker is in its open 

position and the closing springs are fully loaded. 

2) Electrical resetting, responsibility of the operator 

The normal electric opening control (contact SO1) must be connected 

in series with contact SY. 

Another opening control is provided (contact SO2), connected 

in series directly to relay KO for S3 - S4 - S5 or connected directly 

to pole A3 of connector X2 for S6 - S7. 

This control must be protected by, for example, a pushbutton 

keyswitch. It should only be used if the information relayed to the 

control station manager allows one to rule out the possibility of the 

tripping having been caused by a short circuit, or if the causes of 

the short circuit have been removed.
