Automotive circuit breakers provide a resetable and reusable alternative over standard fuses for circuit protection, and can altogether replace fuses and fusable links in most applications. Circuit breakers come in 3 types: Type 1 are auto resettable, and once tripped, will attempt to reset the circuit, or 'cycle', as the internal elements of the breaker cool down. Type 2 (trip and hold) are called modified reset, and will remain tripped until the power is removed from the breaker. Type 3 circuit breakers are manual resettable, and require that a button or lever be pushed in order to reset the breaker. We carry thermal circuit breakers from the leaders in the transportation market, Cooper Bussmann and Carling Technologies. Our circuit breaker selection include the following: ATC and Mini style breakers, which can replace traditional fuses in many applications. High Amperage weatherproof breakers for higher current protection from 50 to 150 amps. The famous Bussmann 'Short Stop' brand, a workhorse in 12 and 24 volt circuit protection from 5 to 50 amps. Panel mount circuit breakers with 1/4" quick connections for mounting into panels with the amperage printed on the reset button.
