    Three-Phase Line-Line VoltageThe Voltage Line-Line knob on the PMPU-FA8 has two ranges (left): a 190-250V low voltage scale and a 380-500V high voltage scale. The unit auto senses the 3-phase line-line voltage when applied and automatically selects the appropriate range.
    Power ConsumptionLess than 40VA.
    Phase LossUnit 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.
    UndervoltageFixed at 90% 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 fixed 4 second trip delay. It will reset at +3% of the Undervoltage trip setting.
    OvervoltageFixed 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 fixed 4 second trip delay. It will reset at 107% of the line voltage setting.
    Phase UnbalanceFixed 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 a period longer than the fixed 4 second trip delay.

    LifeMechanical: 10,000,000 operations; Full Load: 100,000 operations
    TemperatureOperating: -28o to 65oC (-18o to 149oF); Storage: -40o to 85oC (-40o to 185oF)
    MountingUses 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.
    ResetAs standard, the PMPU-FA Series relays are in the Automatic Reset mode. However, they can be set in the Manual Reset mode by connecting an external N.C. switch across terminals 6 and 7. Upon application of line voltage, the PMPU-FA8 Series will go into Manual Reset mode if it recognizes a closure across terminals 6 and 7. After a fault clears, the relay will not reset until the N.C. switch is opened. Note: When the unit is in the Manual Reset mode, the N.C. switch must be opened after each Power-up to reset the relay and resume normal operation.
          Series Features
    PMPU-FA8 Series PHASE LOSS, PHASE REVERSAL, PHASE UNBALANCE, UNDERVOLTAGE & OVERVOLTAGE
    Series Description: The PMPU-FA8 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 PMPU-FA8 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 PMPU-FA8 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. All other settings for undervoltage trip point, trip delay, restart delay and unbalance trip point are fixed for ease of setup. They utilize an industry-standard 8 pin octal socket
