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 initiating a trip condition when an operating characteristic exceeds a corresponding tripping parameter. Additionally, a fault indicating and selecting arrangement which utilizes a trip curve graph to assist in the operation of the circuit interrupter, is also included.
