Description
Upgrade your shore-power system with the SmartPlug 50 Amp Female Connector, engineered to deliver safer, cooler, and more reliable electrical performance than traditional twist-lock plugs. Designed as a retrofit connector for existing 50A shore-power cords, this SmartPlug system offers superior conductivity, easier operation, and unmatched protection against overheating and moisture intrusion.
Built for demanding marine environments, the SmartPlug’s innovative straight-in design increases contact surface area, eliminates twisting, and ensures a secure, vibration-proof connection every time—even in low-light or rough conditions. With advanced weatherproof sealing and a multi-point locking system, this connector provides the highest level of safety and durability for your boat’s electrical system.
Features
- Expanded pin and clip contact area dramatically improves electrical conductivity during high-amp loads, reducing heat buildup and preventing burnouts
- The ergonomic plug body and push-in design ensure the connector aligns correctly every time
- Side locking clips secure the plug firmly into the inlet, eliminating strain on the pins and preventing accidental disconnects caused by cord movement
- Multi-fin silicone gaskets inside the plug and inlet cover create a tight seal that blocks moisture, salt, and corrosion for long-term reliability
- Designed for harsh marine environments with rugged construction and superior electrical safety
- Ideal for sailboats, powerboats, yachts, houseboats or any vessel upgrading from traditional twist-lock connectors
