We have been installing these breakers for a while and it seems like 1/4 of them will rattle or buzz under load. And I don't mean full load, I mean under any load. Good price, and they work other than sometimes they buzz

The DIN rail breakers system is very nice and easy system I really like it there are not compatibility issues, and there are ways very much like we use to do and then some, I have been using them in DC, the prices are better so now using them in AC, very happy as now I have other components like power displays A, V, W and so on.

These breakers are pretty decently made and have a durable casing. The flipping of the switch is nice and solid with almost zero play. The din is thick enough to resist flexing, some others I have looked at late bins very easily. Terminal connections are nice and solid inserting the wire and grabs firmly onto it

Good breakers. Not great, but good, and priced as such. I use them for a small home grid solar setup and I’d use them again.Get the expensive ones if you’re pulling a lot of current
