IDK... Update* 12/2/25 Do Not Buy
Idk.. I have the 125 amp breakers and they get burning hot when pushing them around 120 amps. I bumped current to 135 to see what they would do and they quickly got to the point where they could burn you within a few seconds. I didn't let it go long enough at that current because I thought it was going to start burning the breaker. Works good as a disconnect, and might even be ok if you have a gross over current doubling the amperage but I don't like how hot it gets without cutting out near its rated load. If I have an extra breaker at the end of my project maybe I'll do some more testing to see if it will burn up. Update* 12/2/25 I bought 6 or 7 of these things. 4 or 5 no longer work. So I did a high current test and pushed about 150a through a breaker. The 2 gauge wire stayed warm except for where it tied into the breaker. It got hot enough that it started to burn the 105c rated wire. I disconnected the system before fire but the breaker did not trip untill 30 minutes after the load was disconnected. A melted area occurred on the breaker and the wire was discolored. It hit roughly 260+ degrees before I shut it off and was climbing. So it failed my testing. Besides that A few tripped from normal use and no longer are able to reset. Another couple do reset but the contacts inside are bad. Honestly these things are a major liability and should be pulled from amazon. I pulled the remaining functioning breakers from my system because I no longer trust them to protect anything. Wish I could return.
