GM1851 Datasheet GROUND FAULT INTERRUPTER

Manufacturer: Unisonic Technologies

General 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.
