The Macromatic PAP400 is a three phase monitor relay. This 8 pin plug in relay has a nominal voltage of 400V. It monitors against phase reversal, phase loss and undervoltage with an output of 10A SPDT. The diagram on top of the relay depicts how the LED will indicate the current status. When everything is functioning correctly, the LED is green. When an error is detected, the LED glows or blinks red. The PAP400 uses an 8 pin 70169-D octal socket. Note: Image is an approximation. Actual part may differ.

Like the rest of the PAP series, the PAP400 makes use of "True RMS voltage measurement". The analog to digital sensing circuitry in True RMS voltage measurement is able to give more precise monitoring of phases and voltages. One of the advantages of the PAP400 is the ability to still monitor all the voltages while indicating the fault, even if a phase is lost. When used on system voltages above 300V, a 600V rated socket is needed. The unit stays energized as long as the phases are in the right order once the right voltage is introduced. Undervoltage is can be adjusted to a point between 75-95% of the nominal voltage. When any one of the three phase errors is detected, the relay will de-energize, remaining in that state until the problem is fixed. The relay is able to restart automatically without needing a manual reset
