Phase Failure Relay

Minilec (India) Private Limited

Phase Failure Relay is a negative sequence voltage sensing phase failure relay. It is best suitable for three phase loads or three phase motor / pump loads only. It offers protection against phase failure, phase unbalance, phase sequence reversal, under voltage & over voltage faults. It is useful for incoming side, mains supply monitoring, general voltage faults, AMF/Transfer switch panels & pump control panels. It is available in DIN Rail mounting enclosure.
