Hubbell M4100C12 100A 125/250V Female Connector — Product description
Equip your vessel with the reliable power connection it deserves using the Hubbell M4100C12, a premium 100A 125/250V female connector designed specifically for demanding marine environments. As part of Hubbell Marine's pioneering lineup—the first to deliver true 100-amp marine-grade solutions—this watertight connector ensures seamless shore power integration for yachts, boats, and larger watercraft. Built to exceed industry benchmarks set alongside the National Electrical Code and American Boat & Yacht Council, it stands out for its rugged construction and unwavering performance where others falter.
Superior Build for Harsh Marine Conditions
Crafted from yellow Zytel® super-tough nylon, the M4100C12 resists corrosion, impacts, and environmental stressors like saltwater exposure and UV rays. Its gasketed design creates a fully watertight seal, preventing moisture ingress that could lead to electrical failures. With a generous cord grip range of 1.00 to 1.94 inches (25.4–49.3 mm), it accommodates a variety of cable sizes for custom setups on extension cords or adapters.
- 100A Capacity: Handles full amperage loads without voltage drop, ideal for powering high-demand onboard systems like air conditioning, lighting, and appliances.
- 3-Pole, 4-Wire Configuration: Delivers stable 125/250V power for 3-phase or split-phase shore connections.
- UL Listed & ABYC Compliant: Meets stringent safety standards, giving boat owners peace of mind during inspections and insurance reviews.
- Versatile Mating: Perfect for plug-to-connector interfaces on custom cable assemblies—note it pairs exclusively with compatible plugs, not direct shore inlets.
Why Boaters Trust Hubbell M4100C12 for Shore Power

Pro Tips for Installation and Maintenance
To maximize longevity, pair the M4100C12 with Hubbell's matched shore power inlets or plugs for optimal alignment and sealing. Always inspect gaskets before use, and apply marine-grade dielectric grease to contacts for enhanced corrosion resistance. For dockside setups, ensure proper strain relief on cables to prevent pull-out under wind or wave stress. Regular cleaning with freshwater rinses keeps it performing like new season after season.
