HRN-55 | Relay for protecting phase sequence and failure

  • replacement for HRN-51 and HRN-51N
  • the relay controls the sequence and phase failures (e.g. checking the correct rotation of motors, drives, etc.)
  • relay designed for monitoring 3-phase networks
  • HRN-55 - power supply from all phases, i.e. that the function of the relay is maintained even in the event of a failure of one of the phases
  • Fixed delay T1 (500ms) and adjustable delay T2 (0.1 - 10s).
  • The faulty state is indicated by LED and output contact of relay is OFF.
  • Output contact: 1x switch 8A / 250V AC1
  • 1-MODULE, DIN rail mounting
