Phase Monitor Relay for 480VAC Systems

The Macromatic PAP480 is a plug-in phase monitor relay designed for industrial electrical controls and automation. It accepts a 480V AC input at 50/60 Hz and monitors for phase loss, phase reversal and undervoltage conditions. The octal base unit features a transparent housing and SPDT contact form rated at 10 A @ 277V AC or 7 A @ 30V DC.

Suited for Three-Phase Protection Needs

This relay suits maintenance teams and panel builders who need automatic restart with a one-second delay after a fault clears. It fits standard 8-pin octal sockets and operates up to 149 degrees F with 100,000 electrical operating cycles. Buyers requiring monitoring of additional parameters such as overvoltage or phase unbalance should look at other devices.

480V AC Input Voltage Decides Compatibility

The single specification that determines fit is the 480V AC input voltage. If the three-phase supply is not 480V AC, this relay will not function correctly. All other features — SPDT contacts, auto restart, plug-in mounting — support that core requirement.

Questions about this item

How much heat does the PAP480 generate when monitoring a 480V three-phase supply continuously?

The relay body measures 2.9 in deep, 2.4 in high and 1.7 in wide, with a maximum operating temperature of 149 Degrees F; no separate power-dissipation figure is provided.

What socket or base must already be in the panel for the 8-pin PAP480 to plug in?

It requires an industry-standard octal (8-pin) plug-in socket rated for at least 10 A at 277 V AC or 7 A at 30 V DC.

Will the PAP480 coordinate with an existing electromechanical relay that also uses an octal base?

Yes, both devices share the same 8-pin octal footprint, so the PAP480 can occupy the same socket style and operate at 50/60 Hz alongside the older relay.
