| Product Attribute | Attribute Value |
| Type | Reversal, Loss, Unbalance, Under/Over Voltage |
| Coil Voltage | 460-600V |
| Contact Configuration | SPDT + SPNO |
| Mounting | 8 Pin Plug-in |
| Contact Current | 5 Amps |
| Power Consumption | Less than 40VA. |
| Phase Loss | Unit trips on loss of any Phase A, B or C, regardless of any regenerative voltages. |
| Phase Reversal (Out-of-Sequence) | Unit trips if sequence (rotation) of the three phases is anything other than A-B-C. It will not work on C-B-A. |
| Undervoltage | Adjustable from 80-95% of the line voltage setting. Unit trips when the average of all three lines is less than the adjusted set point for a period longer than the adjustable trip delay. It will reset at +3% of the Undervoltage trip setting. |
| Overvoltage | Fixed at 110% of the line voltage setting. Unit trips when the average of all three lines is greater than the fixed set point for a period longer than the adjustable trip delay. It will reset at 107% of the line voltage setting. |
| Phase Unbalance | Adjustable from 2-10% 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 a period longer than the adjustable trip delay. |
| Output Contacts | SPDT + SPNO 5 A @ 277V AC / 5A @ 30V DC; 1/3HP @ 120/240V AC, B300 Pilot Duty |

| Mounting | Uses an 8 pin octal socket. Requires a 600V-rated socket when used on system voltages greater than 300V such as Macromatic Catalog Number 70169-D. |
| Series Features |
| PMP-X Series PHASE LOSS, PHASE REVERSAL, PHASE UNBALANCE, UNDERVOLTAGE & OVERVOLTAGE |
| Series Description: The PMP-X Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase loss, phase reversal, phase unbalance, undervoltage and overvoltage. These products detect single phasing and unbalanced voltages regardless of any regenerative voltages. Utilizing an advanced microprocessor-based design allows true RMS voltage measurement with full wave monitoring. This provides a more accurate method to measure the voltages, regardless of load type or wave shape, and results in improved protection across more applications. True RMS voltage measurement ensures accurate sensing in most generator and other applications with non-sinusoidal wave forms, eliminating nuisance tripping. Full wave monitoring provides a more accurate method to measure the voltages, regardless of load type or wave shape, resulting in improved protection across more applications. Unlike similar three-phase monitor relays, the PMP-X Series will continue to function even with a lost phase. They are the only line-powered units in their class to retain fault indication and continuous monitoring of all voltages during a phase loss, increasing the ease of troubleshooting and the level of protection. The PMP-X Series is a true universal product, with three units that work on a wide variety of adjustable line-line voltages to cover more global applications. Additional knobs allow adjustment of the undervoltage trip point, trip delay, restart delay andunbalance trip point. They utilize an industry-standard 8 pin octal socket. The PMP-X series also provides an additional isolated SPNO contact that can be used for signaling separate PLC, SCADA, or alarm circuits or controlling secondary loads. |
| Operation: Manual reset option works with external switch to reset the relay from outside the enclosure |
