WirthCo 31117 40 Amp Circuit Breaker Stud

A WirthCo Battery Doctor® circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Unlike a fuse, which operates once and then needs replacement, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Our Wirthco Battery Doctor® circuit breakers are made in varying sizes, and types. Wirthco Engineering supplies various blade and three stud mounted styles, plus manual and switchable reset circuit breakers that hold up to 200 Ampere.
