Relay for monitoring 3-phase sequence and phase failure, with neutral

Ref. MV55N

Three-phase control relay with sequence supervision, phase loss and voltage imbalance. Suitable for 3x400V AC systems, with adjustable thresholds and programmable disconnection delay. Powered by L1-N, with which the relay also monitors after neutral interruption. 8 A relay output with LED indication of network status. For three-phase networks with neutral. Efficient solution for the protection of motors, pumps and three-phase machinery in demanding industrial environments.
