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.
