Voltage Sensing Relay 240V AC

The Macromatic VAKP240A monitors single-phase AC lines for overvoltage and undervoltage conditions. It uses an octal plug-in base with eight pins for quick installation in standard industrial sockets. The transparent housing allows visual inspection of the internal mechanism. This relay suits control panels that must protect downstream equipment from supply excursions.

Octal Base Plug-In Integration

The unit mounts directly into an octal socket without DIN-rail hardware or screw terminals. Its SPDT contact form provides one change-over circuit rated at 10 A @ 240V AC or 7 A @ 30V DC. The pickup range spans 180 to 300V AC while the drop-out band sits at 75 to 95 percent of the set point. Wiring is reduced to the socket itself, freeing panel space for other modules.

Sustained Load Behaviour

Electrical operating durability is rated at 100,000 cycles under rated load. The relay operates continuously at up to 149 degrees Fahrenheit ambient temperature. Contact ratings remain stable at 10 A AC and 7 A DC across the 50/60 Hz frequency range. The device maintains consistent trip points during prolonged exposure to voltage variations.

Questions about this item

How many continuous operations will the 10 A contacts survive before wear becomes the limiting factor?

The relay is rated for 100 000 electrical operating cycles at the listed contact ratings.

What temperature rise should be expected inside the enclosure when the relay runs continuously at 240 V AC?

Maximum operating temperature is 149 °F, so the enclosure must stay below that limit during all-day operation.

Which socket style is required to mount this relay in a control panel?

It uses an 8-pin octal plug-in base that fits standard octal sockets.
