ABSTRACT:
A circuit breaker includes separable contacts, an operating mechanism structured to open and close the separable contacts, and a trip mechanism. The trip mechanism includes a sensor structured to sense current flowing through the separable contacts, a processor cooperating with the sensor to determine a plurality of different trip conditions responsive to the sensed current, a nonvolatile memory operatively associated with the processor, and a trip actuator cooperating with the processor and the operating mechanism to trip open the separable contacts responsive to one of the different trip conditions from the processor. The processor is structured to save in and retrieve from the nonvolatile memory cause-of-trip information for the different trip conditions including the one of the different trip conditions.
