Blue Sea 7204 AC / DC Single Pole Magnetic World Circuit Breaker - 10 Amp

The Blue Sea 7204 AC/DC Single Pole Magnetic World Circuit Breaker – 10 Amp is a marine-grade electrical protection device engineered to meet American Boat and Yacht Council (ABYC) standards and recognized by UL 1077. This magnetic circuit breaker is the industry standard for both AC and DC electrical systems aboard vessels, protecting critical onboard equipment from overload and short-circuit faults. The 10-amp rating makes it suitable for moderate-load circuits on fishing boats, cruising sailboats, and coastal patrol vessels where reliable, repeatable protection is non-negotiable.

The magnetic tripping mechanism responds instantly to overcurrent conditions, cutting power before damage occurs to wiring or connected systems. Blue Sea's design is TUV certified, CE marked for European compliance, and CSA certified for Canadian waters—qualifications that signal its durability in saltwater and freshwater environments alike. The compact form factor (3 x 1 x 5 inches) fits standard panel installations without excessive depth, a practical consideration when panel space is limited aboard smaller vessels.

This breaker is ideal for boaters who run navigational systems, bilge pumps, fish finders, VHF radios, or cabin lighting circuits that demand dependable overcurrent protection. Offshore anglers, liveaboard cruisers, and commercial fishing operations rely on Blue Sea Systems products because a failed circuit breaker at sea can compromise safety and operational capability. Unlike resettable thermal breakers that lag under transient spikes, the magnetic design responds with precision, making it the preferred choice for mission-critical marine electrical infrastructure.
