BEP Heavy Duty CB Module - 50A

The BEP Heavy Duty CB Module - 50A is purpose-built marine circuit protection for the serious boater who demands reliable power management on the water. Whether you're operating a powerful windlass, davit winch, or other high-amperage deck equipment, this modular contour circuit breaker delivers switchable protection where it matters most. Built on proven Bussmann thermal circuit breaker technology, this 50-amp module safeguards critical systems from electrical overload and ensures your vessel stays operational in demanding conditions.

The 705 Contour Circuit Breaker HD features modular sizing with contour lock moulding, allowing flexible installation and configuration across multiple heavy-duty circuits. The thermal design responds intelligently to overcurrent events, tripping before damage occurs to expensive marine motors and winches. Compact at 4 x 3 x 9 inches and weighing just 0.6 lbs, this unit integrates seamlessly into tight engine compartments and electrical panels without sacrificing durability or protection ratings. The 50-amp capacity handles sustained loads from industrial-grade deck hardware while the switchable feature gives you manual control when needed.

Experienced captains and marine electricians rely on this module for retrofit installations, system upgrades, and new builds where redundant circuit protection is non-negotiable. It's ideal for cruising yachts, commercial fishing vessels, and any craft running hydraulic winches or electric windlasses that draw consistent high amperage. Installation pairs easily with existing BEP electrical systems and standard marine panel configurations, making this a go-to choice for serious boaters who understand that reliable power protection pays dividends after years on the water.
