Bueno

Excelente producto y fácil de instalar

This has been in nonstop use since purchased and has worked as intended. Has not tripped yet but the max current in my system is around 60A. It opens the circuit even with 60A DC flowing through it when pulled manually.

Fits and works just like Chint breakers. I use on all my solar edge equipment.

Easy to install, works perfectly.

I got one of these to test out before I got a ton of them. After all, why get dorky on off nobs when you can have levers with breakers in them for extra security! After I installed my solar, I tested out the breaker. When I turn it off, it doesn't cut the volts. There is a small amount of amps getting through. I figured if it doesn't turn off the amps completely, I don't need it but it was already installed so I figured I'd leave it in. I got the 80 amp breaker but I never went above 61.5 amps so I figured I was safe from any kind of melting like some people had in the reviews (i'm assuming they pushed it to 80 to trigger it often or something). After about 1.5 years, my solar went off. I went to investigate and found my positive wires melted completely off and my charring on my negative and positive wires. I had some large copper lugs and crimpers so I cut off the burnt ends and crimped them together as a temporary fix until I can get some time to remeasure and recut cables. It's far better just to have things fail immediately rather than a year later when all your diagrams, cables, tools are in storage somewhere. To have something that initially didn't work but didn't break the system, come in a break the system is infuriating

Worked as expected. Feels solid.
