Additional Details

The relay provides single pole over current protection for power systems. Relay operating time is determined by set definite time. The relay measures the current from 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
