On the expensive side but definitely better quality than the original Zinsco breakers. Great holdover until I get around to replacing my old panel. Bought some extras for when the lever inevitably breaks on the old breakers.

5.0 out of 5 stars Perfect replacement for Zinsco Magnatrip breakers in 66 year old panel.
Reviewed in the United States on November 3, 2020
Verified Purchase
CAUTION!!!! These breakers come in neither the ON or Off position! You need to switch them on and off several times BEFORE they will work properly. Especially the double pole breakers. One side worked fine 1st switch, but it took 3 more on/off switches to get other side working!

These Zinsco breakers are sometimes difficult to find and when you do, they are expensive. The product does what it is supposed to do at a reasonable price.
