BEP Marine Circuit Breakers
BEP Marine Circuit Breakers: Engineered for the Demands of the Sea
When your vessel's electrical system faces saltwater spray, vibration, and extreme temperatures, you need circuit protection that will not flinch. BEP Marine has built its reputation on exactly that — producing circuit breakers and protection devices engineered from the ground up for the uncompromising marine environment. The result is a lineup of circuit breakers trusted by recreational boaters, commercial captains, and professional marine installers alike.
What Sets BEP Marine Apart in Circuit Protection
With a rich history rooted in supporting New Zealand's competitive yachting industry, BEP Marine has consistently pushed the boundaries of innovation, particularly through its contributions to America's Cup races. That heritage of high-stakes, high-performance engineering carries directly into their circuit protection products. BEP engineers and manufactures high-quality electrical solutions for harsh marine and RV environments, and every product meets exacting performance specifications designed to withstand extreme conditions — both at sea and on land.
BEP Marine uses the highest quality materials in its range of control panels, from marine-grade aluminum base plates to Airpax magnetic hydraulic circuit breakers. The choice of Airpax magnetic hydraulic breakers is significant — this technology provides trip-free, reset-able protection that responds to both overcurrent and short-circuit conditions without the heat-related false trips that can plague thermal-only designs in warm engine rooms.
AC and DC Circuit Breaker Options
BEP Marine addresses circuit protection across both AC and DC systems. Their catalog covers marine fuses, fuse holders, and circuit breakers alongside switch panels, DC circuit breaker panels, and AC circuit breaker panels. On the DC side, BEP offers everything from compact standalone breakers and modular circuit breaker modules to full multi-position panels in their Millennium Series and Cruiser Series lineups. AC circuit breaker panels are also available and are ideal for shore power installations and onboard inverter installations.
BEP heavy-duty circuit breakers are single-pole thermal-type switchable reset breakers typically used in auxiliary and accessory circuits, and are sealed for engine compartment and bilge area applications — while the Contour Circuit Breaker Module features a Contour housing with three magnetic hydraulic switchable circuit breakers designed to separate load from the main DC supply.
The Contour Series: Form Meets Function
BEP's Contour heavy-duty circuit breakers allow switchable protection for demanding circuits like anchor windlasses or davit winches, utilizing Bussmann® heavy-duty thermal circuit breakers and designed to match all other Contour power distribution products with modular sizing and locking moldings for easy grouping. These are available in sizes from 80 to 150 amps, making them appropriate for the most current-hungry accessories aboard modern vessels.
