Could be better
The housing that holds the switch has come loose over time, the rubber covers on the bolts don't stay on well. Electric wise, works fine after a year.

Works as expected.
Using this for a while as a back up to the BMS on a 1680 ah battery bank. It has not opened the circuit due to amps. Still, it has remained effective as a switch and does not build up heat (which was a problem with my last unit). My only complaint on the unit is that it is hard to use my 2/0 wires on the terminals with their proximity to the body.

Big Breaker = Big Wire. Period
Just what the inverter needed, I bought the inverter before I purchased the 200amp breaker for my travel lite truck camper. After up grading from 60amp to 200amp I can now run my AC on high.
