Seem well made and reliable so far.
I have two battery banks associated with my solar power system. One consists of AGM batteries that maintains power to just a couple of appliances, including my fridge. The other consists of LifePo batteries that I use to power everything else. Each bank of batteries has its own inverter and I use one of these 125amp breakers between each bank of batteries and its inverter. 125amps is a little low for the size inverters Im running but I prefer it that way. I dont use more than 1500 watts at any one time and wouldnt want to. These would flip at around 1600-1650 watts. I also prefer these over fuses because these are much easier to reset.

Solid copper wire should probably be used on breaker.
This replacement breaker operates cool as long as the stranded connection wires have ferril crimped terminals otherwise the stranded wires get loose and overheat.
