This GFM systems is designed for all polyphase applications and is ideally suited for motor control, motor control centers, and high voltage starters. System
can be wye or delta, ground or resistance grounded. When the ground fault current exceed a pre-selected condition (current and time setting) the relay trips.
The relay contacts can be connected in the control circuit of a motor starter, to the shunt trip of a circuit breaker or similar disconnecting or alarm devices. The
system has an inverse time characteristic to prevent nuisance tripping. The relay tripping current value is f ield adjustable over the trip current range of the
sensor. The adjustable trip time delay relay is f ield setable up 36 cycle.
