The Macromatic PAP480 is a three phase monitor relay that monitors for phase reversal, phase loss and undervoltage. This 8 pin plug in relay has a nominal voltage of 480V, with an output of 10A SPDT. The LED on top will be green if everything is functioning correctly. If the relay finds an error, the LED glows or blinks red. The diagram on top of the unit shows how the LED will indicate the current status. The PAP480 uses an 8 pin 70169-D octal socket. Note: Image is an approximation. Actual part may differ.

The PAP480 utilizes "True RMS voltage measurement" as part of the PAP series. Analog to digital sensing circuitry in True RMS voltage measurement allows the relay to be more precise in monitoring phases and voltages. The PAP480 has a useful feature in that even if a phase is lost, it can still monitor all the voltages while indicating the fault. It is important that this relay be used with a 600V rated socket if the system voltage is above 300V. As long as the phases stay in the right order and do not go under the set undervoltage point, the unit remains energized. The undervoltage point can be set between 75-95% of the nominal voltage. The relay de-energizes if it picks up a phase error. Once the error is fixed, it will energize again on its own.
