Part Number: KCGG142

Function: Overcurrent Protection

Manufacturer: GE’s Grid Solutions, Alstom


KCGG142 datasheet



The KCGG142 is Three phase overcurrent and earth fault relay.

The range of overcurrent relays provides comprehensive protection for phase and earth faults, together with measurements, communications, control and recording facilities.
Within the range, the KCGG relays provide non-directional overcurrent and earth fault protection, while the KCEG relays allow each stage of protection to be selectively
directionalised. The relays in the range are designed to operate with a wide range of ac or dc auxiliary power supplies.
