HRN-56/575V

• 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 3-MODULE HRN-56/208 - 3x 208 V HRN-56/480 - 3x 480 V HRN-56/240 - 3x 240 V HRN-56/575 - 3x 575 V HRN-56/400 - 3x 400 V
• Fixed time delay T1 (500 ms) and adjustable time delay T2 (0 -10 s).
