Detailed description

Designed for demanding marine environments, the MARINCO 6364CRN 50A 125/250V female locking connector ensures a reliable connection for shore power. This 3-pole, 4-wire connector with grounding complies with the NEMA SS2-50R configuration, guaranteeing standardized compatibility. It is made from marine-grade materials, featuring a nylon housing and sleeve, nickel-plated brass corrosion-resistant contacts, and stainless-steel assembly and strain-relief screws.

Design and performance

The 6364CRN incorporates a locking mechanism that prevents accidental disconnections caused by vibrations or boat movement, a notable advantage over non-locking connectors. It can accommodate cables up to 1.2 inches (6-4AWG) in diameter and operates within a temperature range of -40°C to +75°C (no impact). Its ribbed design provides a secure grip, facilitating connection and disconnection operations. A dust-proof seal at the cable entry protects the terminals from contaminants, while an internal self-centering strain relief and a powerful anti-traction system with stainless-steel screws ensure cable fixation.

Installation and certifications

Installation of the MARINCO 6364CRN connector is simplified by terminal pockets and color-coded screws, providing a visual wiring guide. This product is UL certified (File E57672) and CSA certified (File 81290), attesting to its compliance with safety and performance standards. It also comes with a 5-year limited warranty, underscoring its positioning as a durable component for marine electrical installations. It is ideal for connection to a shore power inlet or an existing cable set.

« Technical analysis: MARINCO 50A connector for safe shore power connection »

The MARINCO 6364CRN female locking connector is a critical component for any marina electrical installation requiring a reliable 50A, 125/250V power supply. Its robust nylon construction and nickel-plated brass contacts make it specifically designed for marine environments where corrosion and mechanical stress are constant concerns. The primary functional value lies in its NEMA SS2-50R locking mechanism, which eliminates the risk of accidental power disconnection—a critical safety feature at sea or during dockside operations. This distinguishes it from standard non-locking connectors, providing enhanced safety for crew and equipment.

In terms of installation, the color-coded terminals and screws significantly simplify wiring, even for non-specialized technicians, reducing potential errors. The integrated strain relief and cable clamp system effectively protects conductors from mechanical stress, extending the lifespan of the entire connection. This model is particularly well-suited for medium to large sailboats requiring substantial shore power, where connection stability and safety are paramount. It integrates seamlessly with compatible 50A marina power inlets and cables.
