PMPU PHASE MONITORING RELAY, SPDT, 480VAC

Product Overview The PMPU is a 3-phase Multifunction Monitoring Relay with SPDT, SPST-NC contact and quick connect terminals. This PMP-series monitor relays continuously monitor all voltages of a three-phase system. They are used to protect motors and equipment from expensive damage due to phase loss, phase reversal, phase unbalance, under-voltage and overvoltage faults as well as rapid cycling. These products detect single phasing and unbalanced voltages regardless of regenerative voltages. The PMP-series incorporate a microprocessor-based design capable of advanced signal processing including true RMS voltage measurement. Innovative analog to-digital sensing circuitry allows for true full-wave monitoring of all three phases, delivering the highest level of protection possible. True RMS voltage measurement ensures accurate sensing in most generator and other applications with non-sinusoidal wave forms, eliminating nuisance tripping. Pilot duty rating Compact plug-in case utilizing industry-standard 8-pin octal socket Manual reset option works with external switch to reset the relay from outside the enclosure Full fault indication on top of unit for easy troubleshooting Applications IndustrialThis listing is for Each.
