.. LM1851 Ground Fault Interrupter June 1992 LM1851 Ground Fault Interrupter General Description 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...
