HRN-56 - Power voltage: 240 V AC
HRN-56 - Power voltage: 240 V AC
The relay monitors undervoltage, sequence and phase failure
Description
HRN-56 | Relay for monitoring phase sequence and failure
- Relay monitors phase sequence and failure (e.g. control of correct motor winding etc.).
- Relay is designated for the monitoring of 3-phase networks.
- Supply from all phases which means that relay is functional also in case of one phase failure.
- Fixed time delay T1 (500 ms) and adjustable time delay T2 (0 -10s).
- The faulty state is indicated by LED and by the opening of output relay contact.
- Output contact 1x switch 8 A / 250 V AC1
- 1-MODULE, 3-MODULE, DIN rail mounting.
