MACROMATIC INDUSTRIAL CONTROLS PMDU 3 PH MONITOR RELAY DIN M190-500V 10A DPDT

3-phase Monitor Relay. When the proper 3-phase line voltage is applied to the unit and the phase sequence (rotation) is correct, the relay is energized after the Restart Delay is completed. Any one of five fault conditions will de-energize the relay after a delay. As standard, re-energization is automatic upon correction of the fault condition. Manual reset is available if an external momentary N.C. switch is connected to terminals 4 and 5. A bi-color status LED indicates normal condition and also provides specific fault indication to simplify troubleshooting. Universal voltage range of 190-500V AC on PMDU provides the flexibility to cover a variety of applications with one unit (separate 575V-only version available). Protects against phase loss, phase reversal, phase unbalance, under voltage and overvoltage. True RMS voltage measurement ensures accurate sensing across more applications. Retains fault indication and continues monitoring all voltages even with a lost phase. Manual reset option works with external switch to reset the relay from the outside of enclosure. Full fault indication on top of unit for easy troubleshooting. Pilot Duty Rating.
