• Under voltage monitoring
  • Monitors own three phase, 4-wire supply
  • Detects incorrect phase sequence, phase and neutral loss
  • Adjustable Trip level and Time delay
  • SPDT Relay output
  • 17.5mm wide, DIN Rail mount

The product monitors it’s own three-phase supply and for the output relay to energise, all phases (and neutral) must be present, the phase sequence correct and the phase to neutral voltages above the set trip level. If any of these conditions are not met, the relay will de-energise.
