RS PRO Datasheet

RS PRO 3-Phase Under/Overvoltage Relay

The RS PRO 3-Phase voltage 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, phase sequence correct, and measured phase asymmetry/unbalance within the set limits. 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

Monitoring relay

Compact 17.5mm DIN rail housing

Microprocessor based

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

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

Monitors own supply and detects if one or more phases exceed the set Under or Over voltage trip levels

Operates irrespective of phase sequence

Detects phase loss and neutral loss1

Adjustments for Under and Over voltage trip levels and Time delay

DPDT relay output 5A

Green LED indication for supply status and Red LED for relay status
