Blue Sea 7200 AC / DC Single Pole Magnetic World Circuit Breaker - 5 Amp

The Blue Sea 7200 AC/DC Single Pole Magnetic World Circuit Breaker – 5 Amp is a precision electrical protection device engineered to meet American Boat and Yacht Council (ABYC) standards for marine applications. This magnetic circuit breaker delivers fast, reliable fault protection in both AC and DC power systems, making it essential for any vessel requiring code-compliant electrical safety. Recognized by UL 1077, TUV certified, CE marked for European waters, and CSA certified for Canadian operations, the model 7200 establishes the industry standard for compact marine circuit protection.

The 5-amp rating targets low-amperage circuits common in auxiliary systems—navigation lighting, VHF radio circuits, instrumentation feeds, and cabin equipment. Magnetic trip technology responds instantly to current spikes and short circuits, protecting wiring and components from fire risk without the nuisance tripping associated with thermal-only breakers in variable marine environments. The single-pole design integrates into standard panelboards with a compact 3 x 1 x 5-inch footprint. Standard delay characteristics prevent nuisance trips during normal inrush events while maintaining rapid response to genuine faults. The breaker operates reliably across the temperature and humidity extremes encountered in offshore and coastal boating.

Weekend fishermen upgrading aging electrical systems and serious offshore anglers running modern electronics both depend on Blue Sea circuit breakers to isolate problem circuits without leaving the helm. Cruising sailors operating in international waters benefit from multi-certification compliance—one breaker meets U.S., European, and Canadian regulatory requirements. Liveaboard and commercial operators choose the 7200 for its proven track record in salt-air corrosion resistance and consistent performance across decades of service. Installation requires no specialized tools; the breaker mounts directly into compatible Blue Sea and third-party panelboards using standard DIN-rail or panel-cutout hardware.

Blue Sea Systems' World Circuit Breaker line represents the workhorse of marine electrical protection—engineered for harsh saltwater environments where reliability and code compliance are non-negotiable. The 5-amp model covers the majority of low-current branch circuits in modern marine DC systems and mixed AC/DC installations. Stocking this breaker ensures immediate replacements for failed units or planned system upgrades without weeks of backorder delays.
