Single Pole Definite Time Earth Fault Relay

Application:

The relay provides earth fault protection of Generators,Motors, Transformers, Feeder etc., and where definite time protection is required.

The relay provides earth fault protection for power systems. Relay operating time is determined by set definite time. The relay measures the current from the input CT and if it exceeds the set threshold, it extends a trip signal after the operating time, which is determined by set definite time. The relay output contacts are self reset type. TEST button facilitates testing of relay contacts for trip and alarm circuits.
