HRN-57N | Voltage monitoring relays in 3P with adjustable levels
 

  • 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, L2, L3-N, means that relay monitors also failure of neutral wire.
  • 1-MODULE, DIN rail mounting.
