200Amp Circuit Breaker 30A-300A Inline Fuse Inverter with Manual Reset Breaker for Car Truck Rv ATV Marine Boat Vehicles/Electronic Systems

I used this to be a battery isolator switch in a solar generator project on a 12 volt 100 amp-hour battery, between the battery (+) and the + terminal on the 1500 watt pure sine wave power inverter. Works just fine for that - and I hope I never find out if it works being a circuit breaker, too...

Looks and works well but keep in mind plastic is brittle

While the pictures look close, the actual size of the threaded studs is 1/4 not 3/8 like the pictures suggest. Waaay too small for the 1/0 cable I wanted to use for 150amps Max. This will probably burn and die as soon as you try sending over 100amps thru it.Misleading pictures. Build quality is also just mediocre, nothing special.

Used in a hot rod. Works great

Works great for the winch

Worked as described

This showed up in good time, but was not as described. It comes with 1/4” posts, not the 3/8” posts advertised. My 2 gauge wire with 3/8” eyelets barely fits in the molded space around the posts. The 3/8” holes almost go over the nut included to hold it on. There’s no way this is going to work well without adding a washer mountain. Very stupid.

Its a geat idea if it would last i started building a new project about a year ago and didn't last to the finish line.It maybe had 8 hrs of run time on it.I used it between the battery and alternator witch put out 130 amp
