BEP Marine: Excellence in Marine Electrical Distribution

BEP Marine, founded in New Zealand and now part of the Navico Group (alongside Simrad, B&G, Lowrance, and CZone), is the global reference for power distribution and switching aboard vessels. Specializing in motorized battery switches, smart battery hubs, high-current distribution bars, and high-performance marine circuit breakers, BEP has equipped cruising sailboats, luxury yachts, and commercial vessels for over forty years. The brand is recognized for the robustness of its silver-plated contacts, compatibility with the CZone digital switching ecosystem, and the manufacturing quality of its products, all certified to ABYC, IEC, and CE standards. Skysat, leveraging its expertise in offshore racing and pleasure boating equipment, assists customers in selecting and integrating BEP solutions — from a simple 275 A battery switch to a 600 A multi-battery intelligent network controlled via NMEA 2000.

• 714-140A-DVSR / 716-V/H/SQ-140A-DVSR / 719-140A-DVSR: Distribution clusters integrating VSR + battery switch + bank selection, available in single-, dual-, and triple-engine versions with dedicated banks.

Heavy-Duty Circuit Breakers (HD)

BEP’s 185 Series circuit breakers cover the protection needs of main onboard circuits, from starter to windlass. Their reliable thermal tripping and manual reset eliminate the need for fuse replacements at sea. See the full range in the Electrical Distribution collection.

💡 Skysat’s Advice

For optimal BEP installation, Skysat recommends always sizing the battery switch based on the total cranking current (not just continuous current) and prioritizing motorized versions (720-MDO or 701-MDVS series) for boats with restricted engine-compartment access. For multi-battery configurations, the Smart Battery Hub is the modern choice: it replaces multiple discrete components (battery switches, VSRs, monitoring) with a single integrated, NMEA 2000-communicating unit, greatly simplifying wiring and maintenance. Finally, consider combining the BEP range with the CZone ecosystem for digital switching on secondary panels: the benefits in reliability, weight savings, and modularity are substantial.
