| Ground Fault Relays WILMARTM 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 ....................... Leakage Current Range ................... 10 to 60 mA Control Voltage ................................ See Part Number Selection Output Contacts ............................... One set N.C., one set N.O. Operating Temperature .................... 40oC to +65oC Contact Ratings ................................ 10 amp resistive at 250 Vac, 8 amp. resistive @ 30 Vdc Notes: 1. Remove screw for acess to the pick-up adjustment potentiometer. 2. Clockwise rotation of the adjustment potentiometer will raise the relay sensitivity.
