Review on Zesugo Amplifier Waterproof Surface Mount Protector Replacement Parts by Douglas First

I am installing this circuit breaker between a 2000w inverter and a 12v 150ah LiFePO4 battery. The main purpose of the inverter is to provide backup power for my grid equipment and a drain pump when needed. My battery doesn't have a BMS installed, but it does have balancing cables that I use to balance an RC charger (iCharger S6). This battery has a continuous discharge rate of 3C (i.e. 450A), which is enough to melt wires and possibly start a fire if something goes wrong. Depending on the inverter's own power, a 2000W inverter shouldn't draw much more than around 167A, so a 150A breaker would be a reasonable choice. Although the inverter should already have built-in overcurrent protection, I decided to add this circuit breaker as a precaution in case of a short circuit inside the inverter. This circuit breaker looks and feels like a solidly built product. The "off" button feels accurate when pressed. The reset lever makes a pleasant click when switched on. I think this should work fine for my setup.
