• Under and Over voltage monitoring (Window)
  • Monitors own three phase, 3-wire supply
  • Detects incorrect phase sequence and phase loss
  • Fixed Trip levels and adjustable 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 must be present, the phase sequence correct and the phase to phase voltages within the fixed Under/Over trip levels. If any of these conditions are not met, the relay will de-energise.
