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
