Industrial voltage sensing relay

The Macromatic VAKP120A monitors 120V AC supply lines for overvoltage and undervoltage conditions. It uses an octal base with eight pins and provides a DPDT contact rated at 10 A for 240V AC or 7 A for 30V DC. The pickup range spans 90 to 150V AC with a drop-out threshold between 75 and 95 percent.

Compatibility check before ordering

Verify that your control circuit operates at 120V AC and fits the octal socket layout. The relay body measures 2.9 in deep, 2.4 in high and 1.7 in wide, so confirm panel cut-out and clearance. Ensure the 50/60 Hz frequency rating matches your supply and that the 10 A contact rating suits the load.

Integration into a control panel

The plug-in mounting allows quick installation or replacement without rewiring. Transparent housing lets you inspect contact status visually. The relay frees up panel space by combining overvoltage and undervoltage monitoring in one unit rated for 100,000 electrical operations at up to 149 Degrees F.

Questions about this item

Does the relay include the octal socket or must it be bought separately?

Only the relay with its eight pins is supplied; a matching octal socket is not included and must be purchased separately if one is not already installed.

How do I decide between the 90 V pick-up and the 75–95 % drop-out settings?

The pick-up range is fixed at 90 to 150 V AC and the drop-out range is fixed at 75 to 95 percent of the nominal voltage; there are no user-selectable versions to choose from.

What load can the DPDT contacts actually switch in a 120 V AC control circuit?

The contacts are rated for 10 A at 240 V AC and 7 A at 30 V DC, so on a 120 V AC circuit they can handle up to 10 A resistive load.
