The Macromatic PAP575 is a three phase monitor relay that checks for phase reversal, phase loss and undervoltage. This 8 pin plug in relay has a nominal voltage of 575V, 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 PAP575 uses an 8 pin 70169-D octal socket. Note: Image is an approximation. Actual part may differ.

As part of the PAP series, this electrical relay makes use of "True RMS voltage measurement" to help protect your equipment. Analog to digital sensing circuitry in True RMS voltage measurement allows the relay to be more precise in monitoring phases and voltages. Even if a phase is lost, the unit can still monitor all the voltages while indicating the fault, adding to the overall protection. It is important that this relay be used with a 600V rated socket if the system voltage is above 300V. Applications using 575V are often found in Canada. These relays are also ideal for heavy duty applications, such as in the mining or petrochemical industries. This unit is energized as long as the phases stay in the right order and the voltage is correct. It de-energizes after a delay if it detects a phase error. Once the error is fixed, the relay will energize again on its own. The undervoltage point can be set between 75-95% of the nominal voltage.
