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.
Relay for voltage control MVR 54
- 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
