Automotive Circuit Breakers and Electrical Circuit Breakers

Waytek carries thousands of automotive circuit breakers for auxiliary and accessory circuits on trucks, buses, recreational vehicles, marine, and construction equipment. From auto reset circuit breakers to blade type electrical circuit breakers, our selection covers all electrical projects. Waytek has rugged and reliable circuit breakers for exceptional circuit protection performance.

To make a selection on which automotive circuit breaker is best for your application, you must consider where the circuit breaker will be mounted, the current rating you need the electrical breaker to carry, and the type of reset method. There are four electrical circuit breaker types:

  • Type I Automatic Reset, which means the circuit breaker keeps cycling on and off until the overload is removed
  • Type ll Modified Reset or Non Cycling, where the circuit breaker doesn't reset until the overload is removed or powered off
  • Type lll Manual Reset with the trip indication shown on the body of the circuit breaker and it must be manually reset
  • Type lll Switchable, which is similar to Type lll Manual Reset, but the circuit breaker has a manual trip button
