HFC Instantaneous Overcurrent Relay - Legacy

HFC Instantaneous Overcurrent Relay

Manufacturing for this product has been discontinued. As an alternative, please refer to the 3 Series relays.

The Type HFC relays consist of one or more hinged armature instantaneous overcurrent units. Each unit has two electrically separate contacts and is assembled in a single end drawout type C1 case. The units have a high-seismic rating, and include a target which is latched and raised into view when the unit operates. The targets are manually reset by a button on the front of the relay cover.
