Product overview

The ACX2812 is the plug counterpart to the ACX2811 socket, completing the 12-pin flat connection pair. The plug fits on the trailer or caravan wiring cable and connects to the ACX2811 socket on the towing vehicle's tow bar. The dual-row format carries the same seven standard trailer circuits in the 20A row and up to five auxiliary circuits in the 35A row, suited to modern caravans with electrical systems beyond what the standard 7-pin flat can accommodate.

The nickel plated brass pins are secured with Phillips head screws for straightforward terminal tightening and reliable long-term connections. The plastic wire cap protects wiring entries from moisture and debris. Match circuits to the correct row based on current requirements: the 7-pin row for lighting, braking and standard circuits, and the 5-pin row for battery charging, 240V switching, air conditioning and other high-draw services.
