National P/N LM1851 - Ground Fault Interrupter
The LM1851 is designed to provide ground fault protection for AC power outlets in consumer and industrial
environments. Ground fault currents greater than a presettable threshold value will trigger an external SCR-
driven circuit breaker to interrupt the AC line and remove the fault condition. In addition to detection of
conventional hot wire to ground faults, the neutral fault condition is also detected.
Full advantage of the U.S. UL943 timing specification is taken to insure maximum immunity to false
triggering due to line noise. Special features include circuitry that rapidly resets the timing capacitor 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.
