Title:
A circuit interrupter using nonvolatile memory for a diagnostic improvement
Document Type and Number:
Japanese Patent JP6223454
Kind Code:
B2
Abstract:
A miniature circuit breaker includes separable contacts, an operating mechanism structured to open and close the separable contacts, a trip mechanism cooperating with the operating mechanism to trip open the separable contacts, a processor having a routine, a plurality of sensors sensing power circuit information operatively associated with the separable contacts, and a non-volatile memory 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.
