A lot of import DIN breakers are only rated for 50Hz, and while I realize the likelihood of issues is low, I still only use 60Hz rated ones. These were well made, connections were clean (albeit maybe a tad oversized for being 20A), and the switching is solid. Good option.

This AC MCB feels like a good breaker at a great value as an AC circuit breaker. The construction and specs all look good. The indicator light and DIN rail mount are generally standard on these, but they are still nice and help make this an all-around good functional choice based on what I can see so far.Note that it is a Curve C breaker, so look it up and ensure it is right for your application. Curve C is very common, so I raise it more as a point I think most people don't consider, but it may have some bearing on your choice.At two MCBs for the price, this feels like a great value.
