GFR2KNT0 Ground Fault Protection Relay

Selectable Time Delay. Precision Ground Fault Protection.

The Skymatic GFR2KNT0 expands on the trusted design of the original GFR2 relay—now with five selectable time delay settings (0.1, 0.25, 0.5, 0.75, and 1 second), giving you greater control over nuisance tripping and system coordination.

Like all GFR2 models, this relay was developed for a Canadian nuclear station and continues to protect critical equipment in industrial environments today. It is CSA approved and built in the Greater Toronto Area, housed in a DIN-rail mountable enclosure for easy integration.

Our Ground Fault System protects motors, transformers, feeders, and other essential equipment from damage caused by low-magnitude ground currents. It operates reliably on both high and low resistance grounded systems.

This relay requires a compatible current transformer (CT) for proper operation. Browse our ANSI-rated CTs here.
