Abstract
Systems and methods for auto-monitoring a trip solenoid and a switching semiconductor in a circuit breaker comprises determining whether the trip solenoid or the switching semiconductor is open-circuited or otherwise non-operational. The trip solenoid has multiple windings therein and the switching semiconductor has multiple semiconductor switches therein. The circuit breaker automatically performs a designated action if one of the multiple windings or one of the semiconductor switches is determined to be open-circuited or otherwise non-operational. In some embodiments, the circuit breaker is a miniature circuit breaker.
