Monitoring voltage relay HRN-56

• 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:
