发明名称 CIRCUIT INTERRUPTER APPARATUS WITH A BATTERY BACKUP AND RESET CIRCUIT
摘要 53,134 A circuit interrupter includes a means for sampling a conditioned current value and determining operating characteristics related to the current flow through an electrical circuit. Also included is a means for comparing the operating characteristics to preselectable tripping parameters and means for initiating a trip condition when an operating characteristic exceeds a corresponding tripping parameter. Additionally, a fault indicating means energized by a backup energy source following interruption is also included as well as means for preventing interference to the display and operating circuits during power-up and power-down conditions.
