Type I - Automatic Reset - Circuit breaker automatically resets after opening. If the fault still exists, the breaker will continue to cycle between ON and OFF positions until the overload is corrected. These devices are sometimes called "cycling


Type I/Automatic Reset circuit breakers do not address or correct overcurrent or fault conditions. They only react by cycling OFF and ON. Any overcurrent or fault condition that causes any Type I circuit breaker to operate should be corrected as soon as possible. Continual vehicle operation under an overcurrent or fault condition (causing the Type I circuit breaker to cycle) is NOT recommended.
