Monitoring voltage relay
HRN-43N

The full-featured monitoring relay is used for 3-phase network control, network monitoring and protection, voltage regulation from a generator or hydropower plant.

DESCRIPTION

  • monitoring of 3-phase mains:
    - voltage in 2 levels (undervoltage and overvoltage) in range 138-276 V (3x 400 V / 230 V) or 280-480 V (3x 400 V)
    - phase asymmetry (can be switched off )
    - phase sequence
    - phase failure
  • adjustable function „MEMORY“
  • function of second relay (independent / parallel)
  • adjustable delay for short peaks for each level independently
  • HRN-43: for circuits 3x 400 V (without neutral)
  • HRN-43N: for circuits 3x 400 / 230 V (with neutral)
  • galvanically separated supply voltage AC 400 V, AC 110 V, AC 230 V, AC/ DC 24 V
  • output contact: 2x changeover 16 A / 250 V AC1
  • 3-MODULE, DIN rail mounting
