| Introduction: |
| It senses the Negative Sequence Voltage components of the system supply. It is best suitable for 3 phase loads or 3-phase motor / pump loads only. It offers protection against Phase Failure, Phase Unbalance, Phase Sequence Reversal. It is useful for monitoring incoming Mains Power Supply for unbalance voltage faults in Air-conditioning & Pump Control Panels. It is available in DIN Rail mounting enclosure. | |
