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 when  
external full-wave rectification is used, circuitry that rapidly resets  
the timing capacitor.
