RS PRO Phase, Voltage Monitoring Relay, 3 Phase, SPDT, DIN Rail

With this RS PRO three-phase monitoring relay, you can protect your equipment from failure due to undervoltage. This relay is equipped with a microprocessor technology that detects and measures phase-to-phase voltages. When the voltage drops too low, it will break the connection in the circuit.


Adjusting the relay to suit your specifications is quick and easy. The minimum voltage requirement can be changed to up to 500 V and a time delay can be added to ensure that any momentary reductions in voltage won't result in tripping.
