Blue Sea 7214 AC/DC Single Pole Magnetic World Circuit Breaker - 20AMP

The Blue Sea 7214 AC/DC Single Pole Magnetic World Circuit Breaker—20AMP is the marine electrical protection standard trusted across the boating industry. This compact breaker meets all American Boat and Yacht Council (ABYC) Standards and carries UL 1077 recognition, TUV certification, CE marking for Europe, and CSA certification for Canada. Whether you're outfitting a weekend fishing boat or managing complex offshore electrical systems, this breaker delivers dependable over-current protection in a reliable, proven design.

Rated for 20-amp operation in both AC and DC applications, the 7214 handles standard marine power distribution demands across diverse vessel types and configurations. The single-pole magnetic design responds quickly to fault conditions—critical when salt air corrosion and vibration can degrade less robust electrical components. Standard delay characteristics prevent nuisance trips from inrush currents while maintaining sensitivity to genuine overcurrent events. The white finish blends seamlessly into standard marine electrical panels, and the compact 8 x 3 x 8-inch footprint fits easily into confined spaces typical of engine rooms and electrical lockers.

This breaker serves any boat owner prioritizing electrical safety—from commercial fishing operations to cruising sailboats to recreational center consoles. Installation as a main breaker, branch circuit protection, or backup system protection is straightforward for professionals and experienced DIY installers familiar with marine DC and AC systems. The dual AC/DC rating eliminates the need for separate breaker types when protecting mixed electrical architecture common in modern vessels. Because ABYC compliance is often required by insurance underwriters and marine surveyors, specifying the 7214 ensures your electrical distribution meets industry standards and regulatory expectations.
