It's a great fit.
Good connectors.
A bit on the lage side for a miniature breaker but I like it.
Inspire perhaps a bit more confidence over the unknown brand name Chinese breakers.
UL Listed... that's important!

Westinghouse 1-Pole Miniature Circuit Breaker
Westinghouse Control
Reviews with images
A compact solution to my emergency-generator-to-house interface needs.
These seemingly well-made Westinghouse mini-breakers provide a compact solution to my need to safely interface a 3.5 kW emergency generator with four electrically-independent switch-plus-GFCI outlets in my basement. I particularly appreciate the dual-connection terminals on each end, which have allowed me to power two current monitors, as well as connect primary 15 amp loads, and still meet code. See the wiring photo.However, upon installing these Westinghouse mini-breakers for the first time on my breaker box’s din rail, I couldn’t help noticing that only three of these breakers will fit, as is apparent in a second photo. (The box manufacturer claims room for four mini-breakers.) The positioning of plastic posts in the box prevents these particular breakers from occupying the extremes of the din rail, as shown in the third photo. No issue for me, given that I only need two breakers. Moreover, I find no fault with Westinghouse in that regard. I fault the manufacturer of the somewhat-cramped LeMotech breaker box (which I’ve reviewed separately on Amazon), so I’ll not deduct a rating star for that reason.I have not tested — and probably cannot accurately test — the C-curve trip points of these UL-rated and CE-rated breakers. Therefore, I cannot comment on their primary functionality. However, if I discover functional problems during use I’ll likely revisit and down-rate this review. For now, however, I can’t justifiably deduct stars.

Some people noted that this was larger than they expected for a "mini" breaker. "Mini" breakers for DIN rails all have about the same dimensions as this. The "miniature" might be a bit of a misnomer depending on what you're expecting. I didn't see the dimensions spelled out clearly in the Amazon listing, so if you're wondering, these are are 17mm wide, and the total length is about 107mm. Total height with the breaker switch vertical (mid-trip) is about 80mm.
I like how the terminals accept either bare wire or spade/fork connectors. You can see in the image I posted you can get a terminal directly under the screw. Note if you're using stranded wire, I would recommend the use of wire ferrules (and that recommendation isn't specific to this product).
I also did check to see if this product was actually UL listed. I have found a lot of cheap imports proudly claim to be UL certified, but when you do a search in the UL database, you don't find them. Westinghouse, being a major player, I didn't think would lie about this. Indeed, this breaker is readily identifiable in the UL database (screenshot attached).

As described, registered in UL database, nice breaker

This is a nice breaker. Fits nicely on a DIN rail, trips when overloaded. What more could you ask for?Reviewed in the United States on January 13, 2023

This is a good DIN rail mountable circuit breaker. I'd give it 4.5 stars instead of 5 only because it's a little longer than needed which made my ideal installation unusable (see picture). You would think with a title of "Miniature Circuit Breaker", it would be a little sorter. I ended up moving this breaker to a bigger box where it worked well.
