3-Phase Monitor Relay 240VAC

The Macromatic PAP240 is a plug-in phase monitor relay that watches three-phase lines for loss, reversal and undervoltage. It mounts in an octal base with eight pins and carries a single SPDT contact set rated for 10 A at 277 V AC or 7 A at 30 V DC. Auto restart occurs after a fixed 1-second delay once the fault clears.

Industrial control panels needing phase protection

Panels that must disconnect motors or pumps when a phase drops or reverses will use this relay. Systems that require adjustable time delays, multiple restart attempts or communication with a PLC cannot be served by this fixed-delay, non-programmable unit.

Fixed 1-second auto-restart delay

The restart timing is factory set to 1 sec and cannot be changed on the device. If the application demands a longer or selectable delay before re-energising the load, a different relay with programmable timing must be chosen.

Questions about this item

How can I verify the relay is monitoring phase loss and reversal correctly after plugging it into the 8-pin octal socket?

Apply 240V AC three-phase power and confirm the SPDT contact changes state when phase sequence is altered or one phase is removed, indicating proper detection.

What accessories are included and what must be sourced separately for installation?

The relay itself is supplied; an 8-pin octal base or socket and wiring for 240V AC three-phase supply are required separately.

Which version should I select for a 240V AC system needing automatic restart after a one-second delay?

The PAP240 model matches 240V AC input, 50/60 Hz operation, auto restart with a 1 sec delay, and SPDT contacts rated 10 A at 277V AC.
