PMPU-FA12

The PMPU-FA12 is a 3-phase Multifunction Monitoring Relay with DPDT contacts, quick connect terminals. This PMP-series phase monitor relay utilize a micro-processor based design to provide protection against phase loss, phase reversal, phase unbalance, under-voltage and overvoltage and are compatible with most Wye or Delta systems. They protect against unbalanced voltages or single phasing regardless of any regenerative voltages. The relay is energized when the phase sequence and all voltages are correct. Any one of five fault conditions will de-energize the relay. Re-energization is automatic upon correction of the fault condition. A multi-color LED indicates normal condition and also provides specific fault indication to simplify troubleshooting.
