Works good
Seems to work as intended. Nothing has blown up or caught fire yet, so that's a plus. Appears to be good quality though, would buy again.

Great product
This is the second set that I ordered for my boat. The first one last me a couple of years before the switch (leg) broke off. Very durable and will but again.

100A trip rating is right on
I have 2 of these on my small RV type solar array and 2 DCM 110AH batteries one on each battery - hooked to a 2000W operating inverter. Tried to run a 1 HP air compressor on it . If the compressor tank was at zero to start, and the motor warm, the start surge on the motor was just below the 4000W peak that the inverter can do momentarily - but with a restart on it, it pulls hard enough that it tripped 1 and then both as it pulled over the 100A input limit. Turns out on surge, I was trying to pull nearly 400A through them (and way more than the 4000W output). I knew, I tried, and it tripped the breakers. I had an amp clamp type meter on the 12v circuit and they each tripped right at setting. Made me very happy to know that they worked correctly.

Working great
I use these 100A breakers as an overload protection on my solar system. They have daily power throughput of 100VDC at 80A. In total I purchased 10 of these. I am very happy with them. One failed due to heat build up from a loose terminal. Probably manufacturing defect or possibly me over tightening the terminal. Other 9 are still working great 2 years later.

Very poor quality
The plastic is of such poor quality that all the components are completely breaking as you attach or even trip the switch. Upon Discovery how terrible these things are made, I had to rip them all out and replace them with other units but of course I am not able to return them For a refund. You have been warned.
