BB1928C-3P Marine Bus Bar 300V AC/48V DC Terminal Block Power Distribution with Waterproof PC Cover
Product Overview
Model BB1928C-3P is a heavy-duty marine-grade power distribution bus bar engineered for reliable electrical management in boats, yachts, RVs, and other 12V-48V DC systems. Built with a flame-retardant PA66 base and a transparent polycarbonate protective cover, it keeps every terminal clean, insulated, and safe from moisture and dust even in harsh offshore environments.
Key Features
- Corrosion-resistant construction: Nickel-plated copper contact plates resist rust and oxidation, ensuring stable conductivity and low energy loss over years of service.
- Dustproof & splash-proof cover: The clear PC cap shields terminals from rain, salt spray, and accidental short circuits caused by loose tools or cables.
- Tool-friendly wiring: Push-in connection design with stainless steel studs and screws allows fast, secure cable termination without special tools.
- Heat-dissipation optimized: Enlarged contact surface lowers contact resistance and keeps temperature rise under control at continuous loads up to 150A DC.
