LPRC/2/W

  • Under and Over voltage monitoring (Window)
  • Selectable nominals voltages
  • Detects phase and neutral loss
  • Operates irrespective of phase sequence
  • Adjustable Trip levels and Time delay
  • DPDT Relay output
  • 17.5mm wide, DIN Rail mount
  • UL Listed

The product monitors it’s own three-phase supply and can be set for either 3-wire or 4-wire monitoring. For the relay to energise, all phases (and neutral if applicable) must be present and the measured voltages within the set under and overvoltage trip levels. If any of these conditions are not met, the relay will  remain de-energised. This product operates irrespective of the phase sequence.

  • Monitoring function: Under/Over voltage
  • Monitored supply voltages:
    • 3-wire:  380V, 400V or 415VAC
    • 4-wire: 220V, 230V or 240VAC
  • Trip level: Under: 75 – 95%/Over: 105 – 125%
  • Hysteresis: ≈2%
  • Time delay: 0.2 – 10s
  • Output: DPDT 5A @ 250V (AC1)
  • Dimensions(mm): W:17.5 x H:89 x D:66.5
