Voltage monitoring relay in 3P with adjustable levels HRN-54

DESCRIPTION

• It serves to monitor voltage, phase failure and sequence in switchboards, protection of devices in 3-phase mains.
• It is possible to set upper and lower level of monitoring voltage.
• Adjustable time delay eliminates short voltage peaks and failures in the main.
• In case supply voltage falls below 60 % Un (UOFF lower level) relay immediately opens without delay.
• HRN-54: supply from all phases which means that relay is functional also in case when one phase is faulty.
• HRN-54N: supply L1, L2, L3-N, means that relay monitors also failure of neutral wire.
