| Series Description: Voltage monitoring relay in 3P with adjustable level Umin |
- Relay monitors phase sequence and failure (e.g. control of correct motor winding etc.).
- Relay is designated for monitoring of 3-phase networks.
- Supply from all phases which means that relay is functional also in case of one phase failure.
- Supply and monitored supply Un: 1-MODULE HRN-56/208 - 3x 208 V; HRN-56/240 - 3x 240 V; HRN-56/400 - 3x 400 V / 3-MODULE: HRN-56/480 - 3x 480 V; HRN-56/575 - 3x 575 V
- Fixed delay t1 (500 ms), adjustable delay t2 (0.1 - 10 s) and fi xed delay t3 (max. 1 s).
