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.

It serves to monitor voltage, phase failure and sequence in switchboards, protection of devices in 3-phase mains
It is possible to set upper and lower level of monitoring voltage
Adjustable time delay eliminates short voltage peaks and failures in the main
Supply is done from monitored voltage
Faulty state is indicated by red LED and by opening of output relay contact
Output contact 1x changeover / SPDT 8 A /250 V AC1
In case supply voltage falls below 60 %Un (U lower level) relay off immediately opens without delay
MVR 54 - supply from all phases which means that relay is functional also in case when one phase is faulty
MVR 54N - supply L1-N, means that relay monitors also failure of neutral wire
1-MODULE, DIN rail mounting
