HRN-57, HRN-57N | Relay for monitoring over / under voltage in 3-phase mains
• It serves to monitor voltage in a switchboard, protection of devices in
3-phase main.
• 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-N, means that relay monitors also failure of neutral
wire.
• 1-MODULE, DIN rail mounting.

Function description
Relay in 3-phase main monitors size of phase voltage. It is possible to set two
independent voltage levels and thus it is possible to set two independent
voltage levels and monitor e.g. undervoltage and overvoltage independently.
In normal state when voltage is within set levels, output relay is closed and
red LED shines. In case supply voltage falls below 60 % Un (UOFF lower level)
relay immediately breaks without delay and faulty state is indicated by red
LED. In case voltage exceeds or falls below the set levels, output relay breaks
and red LED shines (LED indicates faulty state - flashes when timing).
In case timing is in progress and faulty state is indicated, timing is immediately
stopped.
