The PMPU and PMDU Series provide protection for any 208-480 V three-phase system. The relay is energized and the LED is on when the phase sequence and all voltages are correct. Any one of the five fault conditions will de-energize the relay and provide fault indication with the LED. Features:
Universal Voltage: One Unit Works on Any 208-480 V System
Adjustable Settings on Undervoltage (80-95% of Nominal), Time Delay on Undervoltage Trip and Start-Up and Phase Unbalance Setting (2-10% with Disable)
Choice of Automatic or Manual Reset
Standard 8-Pin Plug-In (PMPU) or 45 mm Surface-Mount (PMDU)
Multi-Color LED Indicates Both Normal and Actual Fault Condition
Compatible with Both Wye and Delta Systems Protects Against:
Phase Loss
Phase Reversal
Phase Unbalance
Undervoltage
Overvoltage Specifications:
SPDT (PMPU); SPDT, SPNC (PMDU) 10 A @ 240 VAC/30 VDC
Dimensions: 1.7" × 2.4" × 3.1" (PMPU); 1.8" × 2.7" × 4.7" (PMDU)
Temperature: –28° to +55°C
