Description
- 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.
- Supplied 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 (UOFF lower level) relay immediately opens without delay.
- Supply L1, L2, L3-N, means that relay monitors also failure of neutral wire.
- 1-MODULE, DIN rail mounting.
