Blue Sea 7201 AC/DC Single Pole Magnetic World Circuit Breaker - 5 AMP

The Blue Sea 7201 AC/DC Single Pole Magnetic World Circuit Breaker – 5 AMP is the marine industry standard for electrical system protection on vessels of all sizes. This compact, dual-voltage circuit breaker handles both alternating current (AC) and direct current (DC) power distribution, making it essential for any boat that runs both shore power and battery-based systems. UL 1077 recognized and certified to American Boat and Yacht Council (ABYC) standards, this breaker provides the overload and short-circuit protection that serious boaters depend on when safety matters most.

The 5-amperage rating addresses moderate-draw circuits—auxiliary pumps, cabin fans, navigation systems, and communication equipment—where instantaneous protection without nuisance trips is critical. The magnetic trip mechanism responds instantly to fault conditions, cutting power before heat damage or fire risk develops. Standard delay characteristics prevent false trips from momentary surge spikes that are common in marine electrical systems. With TUV certification for Europe and CSA certification for Canada, this breaker meets international marine electrical codes, making it suitable for vessels operating in foreign waters or subject to international inspection standards.

Fishing boats, cruising sailboats, commercial vessels, and retrofit marine electrical projects all rely on Blue Sea circuit breakers for long-term reliability in the saltwater environment. The compact form factor fits standard marine panel spaces, and the single-pole design integrates easily into existing distribution systems. Weekend anglers upgrading aging panels and professional captains managing complex electrical systems both specify this breaker because it performs predictably year after year, even in harsh marine conditions where corrosion and vibration stress electrical components.
