Definite Time Single Pole Over Current Relay

Features Software based design Wide auxiliary supply Low burden Principle of Operation: JRC 932 provides earth fault protection for power systems. Relay operating time is determined by the 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 the testing of relay contacts for the trip and alarm circuits.
