Circuit Breakers Available in Bulk

Waytek carries thousands of circuit breakers for auxiliary and accessory circuits on trucks, buses, recreational vehicles, marine, and construction equipment. From hi-amp circuit breakers to blade type electrical breakers, Waytek has rugged and reliable circuit breakers for exceptional circuit protection performance. To make a selection on which 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. Circuit breakers have four types of reset methods: Type I Automatic Reset, which means the circuit breaker keeps cycling on and off until the overload is removed, Type II Modified Reset or Non Cycling, where the circuit breaker doesn’t reset until the overload is removed or the power is turned off, Type III Manual Reset with the trip indication shown on the body of the circuit breaker and it must be manually reset, and Type III Switchable, which is similar to Type III Manual Reset, but the circuit breaker has a manual trip button.

For the most rugged and severe weather applications, Waytek carries marine rated circuit breakers. They comply with SAEJ1171 standards for waterproof circuit protection. Waytek carries circuit breakers for virtually every mobile equipment situation. If you are unsure of which circuit breaker best suits your needs, or if you would like to learn more about the circuit breakers Waytek carries, call 800.328.2724. Our customer service representatives are happy to help.
