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.
