Description

HRN-57 | Relay for protecting over/under voltage in 3-phase mains

  • serves for protecting the voltage in the switchboard (protection of devices and equipment)
  • It monitors the value of voltage in 3-phase main.
  • the relay does not monitor the phase sequence
  • It is possible to set the upper and lower level independently.
  • Adjustable time delay eliminated short voltage peaks and failures in the main.
  • The device is supplied from monitored voltage.
  • The faulty state is indicated by a red LED and by breaking output relay contact.
  • Output contact 1x switch / SPDT 8A / 250V AC1.
  • if the supply voltage drops below 60% Un (UOFF lower level), the relay opens immediately without any delay
  • 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 a failure of the neutral wire.
  • 1-MODULE, DIN rail mounting
