WC1G-120AC

Ground Fault Relays WILMAR™ Protective Relays – WC1G Series - Grounded TERMINAL STRIPS #6 - 32 SCREWS Function: WILMAR Ground Fault Detectors are designed to provide very sensitive Ground-Current protection for motor, equipment and personnel from damage or electrical shock. In a ground system, the leakage current is monitored through a toroidal or doughnut current transformer placed around the supply conductors to a motor, transformer, equipment or outlets. Since the sums of the current in a system add to zero, the relay is responsive only to ground-fault current. Operation: The output contacts are shown in de-engerized position. They will change state when these conditions are met: 1. Control voltage is applied. 2. Leakage current exceed the trip setting. 3.8 3.0 Note: Dimensions in inches.Multiply by values by 25.4 for dimensions in mm. Part Number CT Window Diameter .......................
