A miniature circuit breaker (2) includes separable contacts (4), an operating mechanism (6) structured to open and close the separable contacts, a trip mechanism (8) cooperating with the operating mechanism to trip open the separable contacts, a processor (10) having a routine (12), a plurality of sensors (14,16,18,20) sensing power circuit information operatively associated with the separable contacts, and a non- volatile memory (42) accessible by the processor. The routine of the processor is structured to input the sensed power circuit information, determine and store trip information for each of a plurality of trip cycles in the non- volatile memory, store the sensed power circuit information in the non-volatile memory for each of a plurality of line half-cycles, and determine and store circuit breaker information in the non-volatile memory for the operating life span of the miniature circuit breaker. |
