Description

NEPEAN Power’s Holistic Frozen Contactor Relay (HFC) detects voltage leaks across electrical switching device contacts. This advanced relay system protects personnel from injury, electrical shock, and sparking. By continuously monitoring for leaks, the HFC enhances safety and reliability in various industrial environments, making it an essential component in electrical safety systems.

The HFC – Holistic Frozen Contactor relay has been designed to detect a leakage of voltage across a switching device of 24 volts or more when the switching device is in the open or tripped position.

A Holistic Safety Barrier (HSB) is used in conjunction with this relay. The barrier is a three phase unit used to isolate high voltages from the detection equipment. As the barrier is a three phase unit
leakage on any or all of the phases being monitored will be detected and cause a trip.

The unit has its own internal power supply card.

Features
  • Internal Power Supply
  • Detection circuit is fail-safe and de-energizes on detection of leakage
  • Timer delay function adjustable to 4 – 20 seconds for situations where the system is directly switching motors
  • Factory set to detect a leakage of 24V or more
  • LED indication of power on
  • Used in conjunction with a Holistic Safety Barrier suitable for systems up to 1100V
  • LED warning when the frozen contactor/loss of vacuum fault rises
