SmartPlug 50 Amp Boatside Connector (BF50)

The SmartPlug 50 Amp Boatside Connector (BF50) delivers a safer, more reliable shore power connection for high-amperage marine and RV applications. Designed as a direct retrofit upgrade for traditional 50A twist-lock connectors, the BF50 features SmartPlug’s innovative push-in design that eliminates twisting and ensures proper alignment every time.

Rated for 50 amps at 125/250V AC, this female boatside connector uses straight blade contacts with increased surface area to reduce resistance, overheating, and power loss under heavy electrical loads. A multi-point locking system securely fastens the connector into the inlet, minimizing movement and strain caused by wave action or dock stress.

Built with marine-grade, corrosion-resistant materials and weather-sealed gaskets, the SmartPlug BF50 is ideal for boats, yachts, and RVs seeking improved shore power safety, durability, and performance.

Features:

• Can be used with 125V or 250V service
  
• Can be plugged in easily in the dark or awkward locations effortlessly
  
• 20x more electrical contact means no overheating
  
• Weatherproof seals to eliminate corrosion
  
• Triple locks are stronger and easier to use
  
• Sleeved designs ensures a stable electrical connection every time
