Monitoring voltage relay
HRN-57N

DESCRIPTION

• It monitors value of voltage in 3-phase main.
• It is possible to set upper and lower level independently.
• Adjustable time delay eliminated short voltage peaks and failures in the main.
• The device is supplied from monitored voltage.
• Faulty state is indicated by red LED and by breaking output relay contact.
• Output contact 1x changeover / SPDT 8 A / 250 V AC1.
• Relay doesn’t monitor phase sequence.
• HRN-57: supply from all phases, means that relay is functional also in case of failure in one phase.
• HRN-57N: supply L1, L2, L3-N, means that relay monitors also failure of neutral wire.
• 1-MODULE, DIN rail mounting.
