RS PRO Phase, Voltage Monitoring Relay With SPDT Contacts, 3 Phase, Overvoltage, Undervoltage


Need to protect equipment from failures caused by overvoltage and undervoltage? Try this three-phase monitoring relay from RS PRO. This component comes with microprocessor technology that's able to take measurements of phase-to-phase voltages and break the connection in the circuit if the voltage gets too high or low.

It's quick and easy to adjust the relay to suit your needs. The minimum voltage requirement can be changed to 380 V for undervoltage and 500 V for instances of overvoltage. There's also a time delay that will stop tripping when there are temporary dips in voltage.
