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
