Works as suggested.
Productive and really, really good condition. Plastic housing makes it easy more weather resistant. Just do not tighten it too much or you will break the plastic.

Good replacement for the camper battery circuit breaker.
Had a manual reset-able breaker under the trailer. It got broken and had corrosion. Replaced with this one that is auto reset and has a rubber cover to shield the connectors. Not water tight or proof but better that the original. Direct replacement, nothing extra to purchase.

Clean looking, well made circuit breaker
Works great and seems well made. Also a fair price. I bought it for use in updating my classic Chevy headlight wiring harness. Be careful when using self tapping screws in the side holes, you can end up drilling thru the plastic mount itself. I'm not quite sure what "sheerness" or "warmth" have to do with this circuit breaker but they're both getting five stars!
