• The Relay, JRV 922, provides under voltage protection for power systems. The Relay operating time is determined by the set definite time. The relay, measures the voltage from input PT 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 selfreset type. The TEST button facilitates testing of relay contacts for the trip and alarm circuits.

• The relay provides under voltage protection of Motors, Generators, Capacitor Banks etc.
