RS PRO 3-Phase Failure Sequence & Under-Voltage Relay


The RS PRO 3-Phase voltage monitoring relay is used for connecting to a 3-wire or 4-wire supply. The relay is designed to monitor its own supply and in conjunction with an external contactor, disconnect the supply to the load/equipment in the event of a fault occurring.

How does it work?


For the output relay to energise, all phases (and neutral – if applicable) must be present and measured phase voltages within the set trip levels. The product does not monitor phase rotation/sequence. If any of these conditions are not met, the relay (+ contactor) will de-energise, disconnect the supply and thus protect the equipment.

Features and Benefits


  • Compact 17.5mm DIN rail housing

  • Microprocessor based

  • True R.M.S. monitoring measuring phase to phase (3wire) or phase to neutral (4-wire) voltages

  • Selectable nominal voltages to suit most popular 3-wire or 4wire supply voltages

  • Monitors own supply and detects an Under-voltage condition on one or more phases

  • Detects incorrect phase sequence, phase loss and neutral loss1

  • Adjustment for Under voltage trip level

  • Adjustment for Time delay

  • DPDT relay output 5A

  • Green LED indication for supply status

  • Red LED indication for relay status
