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
