SINGLE POLE OVER CURRENT RELAY JRC 032

OVERVIEW

    Features

  • Software based design
  • Wide setting range
  • Wide auxiliary supply
  • Low burden

Application:

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

SINGLE POLE OVER CURRENT RELAY JRC 032

Principle of Operation:

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
