HRN-54 / Monitoring voltage relay
SKU: | ELK-3720 |
EAN: | 8595188137201 |
Zīmols: | Elko ep |
Umax: : | 105 – 125% of monitored voltage |
Serves to monitor voltage , phase failure and sequence in switchboards, protection of devices
DESCRIPTION
- Serves to monitor voltage , phase failure and sequence in switchboards.
- Supply is done from monitored voltage.
- Fixed T1(500ms) and adjustable T2 (0.1 – 10 s) delay to eliminate short voltage drops and peak.
- In case supply voltage falls below 60 %Un (Uoff lower level)relay immediately breaks with no delay
- It is possible to set upper and lower level of monitoring voltage.
- Monitoring voltage relay in 2 variants:
HRN-54: supply from all phases which means that relay is functional also in case when one phase is faulty
HRN-54N: supply L1-N, means that relay monitors also failure of neutral wire
- Faulty state is indicated by red LED and by breaking output relay contact.
