HRN-43:Relay for complete monitoring 3-phase mains

  • monitoring 3-phase mains:

- voltage in 2 levels 160-276 V (3x400/230 V) or 280-480 V (3x400 V)
- phase asymmetry
- phase sequence
- phase failure

  • function “MEMORY” - manual reset, “RESET” button on front pannel
  • HRN-43 - for circuits 3x400 V (without neutral)
  • HRN-43N - for circuits 3x400/230 V (with neutral)
  • 2 output relays, selectable function of 2nd relay (independent / parallel)
  • fixed (t1) and adjustable (t2) delay to eliminate short voltage drops and peaks
  • galvanically separated supply voltage AC 400 V, AC 230 V, AC/DC 24 V
  • output contact: 2x changeover 16 A / 250 V AC1
  • 3-MODULE, DIN rail mounting
