WebThe output of the sensor is a single pole, double throw relay, so when used to operate a shunt trip circuit breaker operating mechanism, the normally open contact of a normally de-energized model would be the best choice. With the -DEN model contact action, the sensor operates the output relay only when fault over the setpoint occurs.
WebWhen ground current reaches the level set by the trip point adjustment, the relay trips, illuminates the tripped LED and provides an output signal. A precision voltage reference circuit ensures a highly repeatable trip point. … butcher moze buildWebOverload Relay, Electronic, IEC, E300, E200, Sensing Module, Current, 6- 60 Amp, Internal Ground Fault Current, 1-5 Amp, Voltage, UL 600V AC, IEC 690V AC, DIN Rail ... ccs vernon hillsWebThe ground fault sensor/relay accessory provides for sensing differential current in two or more load conduc-tors passing through the sensor.
