Blue Sea 7230 AC/DC Single Pole Magnetic World Circuit Breaker - 50AMP

The Blue Sea 7230 AC/DC Single Pole Magnetic World Circuit Breaker – 50AMP is the marine-grade electrical protection system serious boaters and anglers rely on for dependable main panel isolation. After years on the water, experienced boat owners understand that your vessel's electrical integrity directly impacts safety, equipment longevity, and peace of mind on extended trips. This 50-amp breaker serves as your primary defense against overcurrent conditions, short circuits, and unexpected electrical faults that can cripple navigation systems, pumps, and auxiliary power when you need it most.

Built to meet all American Boat and Yacht Council (ABYC) standards, this breaker carries UL 1077 recognition, TUV certification, and CE marking—certifications that matter when your electrical panel is exposed to salt spray, vibration, and demanding marine environments. The single-pole magnetic design responds instantly to fault conditions while handling both AC and DC loads, making it suitable for hybrid power systems and vessels running alternators, battery chargers, and inverters simultaneously. At just 0.2 lbs and compact 3 x 2 x 5-inch dimensions, installation fits neatly into space-constrained panel layouts without sacrificing the robust construction demanded by maritime duty.

Anglers and cruising boaters upgrading their electrical systems or performing panel maintenance will find the 50-amp capacity ideal for main breakers on fishing vessels, cabin cruisers, and offshore boats drawing moderate continuous loads. The worldwide certification profile ensures compliance whether your boat operates in coastal U.S. waters, Europe, or beyond. Installation requires basic familiarity with DC panel wiring; consult your vessel's electrical schematic to confirm proper main feed connection and ensure grounding integrity before commissioning.
