| Introduction: |
| It is a Power Monitoring Relay. It is best suitable for balanced 3 Phase 3 wire Pump loads for No Load or Belt Failure or Dry Run & jamming or overload conditions. It is effective on higher rating loads (Submersible Pumps, Chemical Pumps, AHU Fans, Screw Compressors). It Monitor the power consumed by pump & protect it against fault conditions. | |
