BEP Heavy Duty CB Module - 135A

The BEP Heavy Duty CB Module 135A is a modular circuit breaker designed to protect high-amperage marine electrical circuits with switchable control and LED status indication. Built around the 705 Contour Circuit Breaker HD platform, this 135-amp unit utilizes Bussmann heavy-duty thermal circuit breakers to handle the demanding loads of windlass systems, davit winches, and other power-intensive marine equipment where reliable overcurrent protection is essential.

The 135-amp rating delivers sufficient capacity for systems requiring substantial continuous current draw while the thermal design provides reliable trip characteristics that protect wiring and equipment from short-circuit and overload damage. The modular contour lock moulding allows multiple units to be grouped together for organized panel mounting, simplifying installation in complex electrical systems. An onboard LED indicator confirms when the circuit is energized, offering quick visual verification of operational status without requiring external testing equipment.

This breaker is built for salt-water environments where corrosion resistance and reliable operation under constant electrical stress separate functional systems from chronic failures. It serves boat owners managing multiple high-load circuits—from anchor-handling systems to electric davits on cruising sailboats and motor yachts—who need predictable, manual-reset protection that integrates neatly into existing panel layouts. The compact footprint (4 x 3 x 9 inches) fits standard marine electrical enclosures without requiring panel redesign.

BEP Marine circuit protection products are recognized across the marine industry for thermal stability in high-vibration, high-temperature conditions typical of engine rooms and galley areas. Heavy-duty breakers like the 135A module are preferred over standard automotive-grade alternatives because they maintain calibrated trip points over thousands of thermal cycles and resist nuisance tripping in systems with inductive loads.
