Review on ⚡ PowMr Reset 12V 30A Circuit Breaker Fuse - Audio Inline Fuse Holder for Car Audio, Stereo Switch, and Solar Inverter System - 2 Pack by Brett Cat

. I use 75 amps max with this 100 amp circuit breaker. One fell through right away. I never expected that, so I didn't test it beforehand. Once turned on, it was half on and intermittent, with no reset or power off. Since it was only the second of four, I just put another one on and looked at it. Update, I took apart the faulty one to see how it failed. I found a plastic trigger formed from a bimetallic rod. It didn't work, it just melted at less than 75% load. Replaced them all with breakers. Too much risk.
