3 Pin Anderson Plug Surface Mount – Power and Ignition Sense in One Connection

The Bluebar 3 pin Anderson plug surface mount gives you a fixed 50A 3 pin Anderson connection point on any flat surface, without cutting the large panel opening a flush mount needs. A 3 pin Anderson plug carries positive, negative and a third wire in a single connector. That third wire is most often used to run an ignition-sense wire from a DC-DC charger to an accessory fused point, so the charger knows when the engine is running.

The housing is built the same way as our dual Anderson surface mount: thick walls, smooth rounded edges and UV-resistant material, made to take a knock in a ute tray, canopy or battery box. It comes with a grey 50A 3 pin Anderson plug and stainless steel fittings for mounting.

What Is a 3 Pin Anderson Plug Used For?

A standard 50A Anderson plug carries two wires: positive and negative. The 3 pin version adds a third position, so you can run an ignition-sense wire through the same connector. The most common use is a DC-DC charger setup. The charger takes power through the main pins and an ignition signal from an accessory fused point through the third pin, so it only charges when the vehicle is running.

Where to Use It

• DC-DC charger installs that need an ignition-sense wire
• Ute trays, canopies and service bodies
• Battery boxes
• Caravans, campers and camper trailers

What’s in the Box

• 1 x 3 pin Anderson plug surface mount housing
• 1 x 50A 3 pin Anderson plug (grey)
• Stainless steel mounting fittings

Built to spec. Made for the track.

** Please don’t overtighten the securing bolts as it is possible to damage the walls

FAQ

What is a 3 pin Anderson plug surface mount used for?
It gives you a fixed 50A 3 pin Anderson connection point on a flat surface, carrying positive, negative and an ignition-sense wire in one plug. It’s most often used in DC-DC charger setups where the charger needs an ignition signal from an accessory fused point.

What’s the difference between a 2 pin and 3 pin Anderson plug?
A 3 pin Anderson plug adds a third connection alongside positive and negative. That extra position is typically used for an ignition-sense wire, which saves running a separate connector.

Is the Anderson plug included?
Yes. A grey 50A 3 pin Anderson plug comes with the housing, along with stainless steel fittings for mounting it.

Does it come in other plug colours?
No. The 3 pin Anderson plug is available in grey only.

How big is the housing?
It measures 105mm long, 93mm wide and 25mm high. The walls are 10mm thick on top and 15mm at the side base.

Will it handle being mounted somewhere exposed?
It’s built for exposed positions: the housing is UV-resistant, with thick walls and smooth rounded edges to help reduce damage if it’s knocked from the side.
