ABSTRACT:
A circuit interrupter includes a circuit arrangement for sampling a conditioned current value and determining operating characteristics related to the current flow through an electrical circuit. Also included is a circuit arrangement for comparing the operating characteristics to preselectable tripping parameters and for initiating a trip condition when an operating characteristic exceeds a corresponding tripping parameter. Additionally, a fault indicating circuit arrangement energized by a backup energy source following interruption is also included as well as circuit arrangement for preventing interference to the display and operating circuits during power-up and power-down conditions.
