Abstract:
A circuit interrupter (2) for a power circuit (4) includes separable contacts (10), an operating mechanism (12) structured to open and close the separable contacts, and a trip circuit (14) cooperating with the operating mechanism to trip open the separable contacts. The trip circuit includes a number of hardware circuits (16,18,20,22,24,26,28,30,32,34) having a processor (34) with a number of routines (38,40,42). The routines provide a number of protective functions (38) structured (40) to detect a number of faults of the power circuit, a number of repetitive test functions for the number of hardware circuits, and a supervisory function (42) cooperating with the number of repetitive test functions. The supervisory function is structured to prevent availability of protection by the number of protective functions from falling below a predetermined threshold as a result of a plurality of intermittent error conditions of the number of hardware circuits.
