GM1851 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD LINEAR INTEGRATED CIRCUIT GROUND FAULT INTERRUPTER - DESCRIPTION The UTC GM1851 can specially provide ground fault protection for AC power outlets in consumer and industrial environments. As ground fault currents greater than a presentable threshold value, it will trigger an external SCR-driven circuit breaker to interrupt the AC line and remove the fault condition. Besides of detection of conventional hot wire to ground faults, the neutral fault condition is detected also. In the event that noise pulses introduce unwanted charging currents and a memory circuit that allows firing of even a sluggish breaker on either half-cycle of the line voltage...
