MVR

MVR 31

MVR31 is a multifunctional voltage monitoring relay used to monitor the value of alternating or direct voltage in 1-phase circuits. Monitors voltage exceeding the upper voltage level (Umax) and ...

MVR 54 monitoring relay

Relay for monitoring over/under voltage, phase sequence and failure. MVR 54 - supply from all phases which means that relay is functional also in case when one phase is faulty.

MVR 54N monitoring relay

Relay for monitoring over/under voltage, phase sequence and failure. MVR 54N - supply  L1-N, means that relay monitors also failure of neutral wire.
