Marinco ConnectPro® 3-Wire Receptacle

The Marinco ConnectPro® 3-Wire Receptacle (MPN: 12VBR) is a watertight electrical connector designed for marine vessels operating across a range of DC power systems. Built with corrosion-resistant, plated brass electrical components, this 3-wire receptacle delivers reliable power distribution in demanding saltwater and freshwater environments where vibration, moisture, and electrical consistency are critical to safe boat operation.

The universal design accommodates 2 or 3-wire configurations across 12V, 24V, 12/24V, 24/36V, and 36V systems—making it adaptable to various vessel electrical architectures without requiring multiple connector types. Perma-Lock screw terminals resist loosening under hull vibration and heavy sea conditions, a critical feature that prevents intermittent power loss during offshore runs. Drain holes integrated into the receptacle body keep water away from electrical contacts, while the included watertight sealing cap provides additional protection when the connector is not in use. The standard 1-1/8-inch diameter mounting hole fits common marine panel openings, and installation is straightforward with supplied mounting hardware.

This receptacle serves recreational anglers, charter boat operators, and offshore fishing crews who depend on consistent auxiliary power for fish finders, GPS plotters, live wells, and navigation equipment. Weekend boaters upgrading aging wiring systems benefit from the modular flexibility, while commercial operators appreciate the durability specifications that support extended duty cycles. The combination of corrosion resistance and vibration isolation makes this connector essential for any vessel with mixed-voltage electrical demands or exposure to harsh marine conditions.

Marinco ConnectPro® products represent industry-standard marine electrical solutions engineered for the specific challenges of saltwater and freshwater boat systems. This receptacle's modular approach to voltage configuration reduces inventory complexity for marine electricians and boat builders managing multiple vessel types or retrofit projects across different power specifications.
