Macromatic PMP-FA Series - Phase Loss, Reversal, Unbalance & Under/Over Voltage Monitor Relays

Macromatic PMP-FA Series - Phase Loss, Reversal, Unbalance & Under/Over Voltage Monitor Relays (Plug-In)
   
The PMP-FA Series Phase Monitor Relays utilize a microprocessor-based design to provide protection against phase loss, phase reversal, phase unbalance, undervoltage and overvoltage, and are compatible with most Wye or Delta systems with no connection to Neutral required. 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.

These products offer a universal voltage design that works on any three-phase system voltage from 208-480V (208 or 240V only on the 11 pin DPDT version). The undervoltage drop-out is fixed at 90% & the overvoltage drop-out is fixed at 110% of operating voltage. The time delay drop-out on undervoltage is fixed at 4 seconds. The percent phase unbalance is fixed at 6%. The time delay on both power up and restart after a fault has been cleared is fixed at 2 seconds.
   
Features:
  • Universal voltage range of 208-480V (208 or 240V on 11 pin) provides the flexibility to cover a variety of applications with one unit
  • Protects against phase loss, phase reversal, phase unbalance, undervoltage and overvoltage
  • Choose between 11 Pin DPDT, 12 Pin DPDT, 8 Pin SPDT & 8 Pin SPDT/SPNO output configurations
  • Automatic Reset
  • Multi-Color LED indicates normal condition and provides specific fault indication to simplify troubleshooting
  • Compact plug-in case utilizing industry-standard 8 or 11 pin octal or 12 pin square sockets

Phase Loss: Unit trips on loss of any Phase A, B or C.
Phase Reversal: Unit trips if rotation (sequence) of the three phases is anything other than A-B-C.
Undervoltage: Fixed at 90% of nominal voltage. Unit trips when the average of all three lines is less than the set point for a period longer than the fixed 4 second delay time.
Overvoltage: Fixed at 110% of nominal voltage. Unit trips when the average of all three lines is greater than the fixed set point for a period longer than the time delay drop-out.
Phase Unbalance: Fixed at 6% unbalance. Unit trips when any one of the three lines deviates from the average of all three lines by more than the adjusted set point for longer than the fixed 2 second time delay.
Output Contacts: 10A @ 240V AC/30V DC, 1/2HP @ 120/240V AC (N.O.), 1/3HP @ 120/240V AC (N.C.) B300 & R300; AC15 & DC13
Life: Mechanical: 10,000,000 operations, Full Load: 100,000 operations
