Ground Fault Relays

Function:

WILMAR™ Protective Relays – WC1G Series - Grounded

WILMAR Ground Fault Detectors are designed to pro-

vide very sensitive Ground-Current protection for mo-

tor, equipment and personnel from damage or electrical

shock. In a ground system, the leakage current is moni-

tored through a toroidal or doughnut current transformer

placed around the supply conductors to a motor, trans-

former, equipment or outlets. Since the sums of the

current in a system add to zero, the relay is responsive

only to ground-fault current.
