Blue Sea 7216 AC / DC Single Pole Magnetic World Circuit Breaker - 25 Amp

The Blue Sea 7216 AC/DC Single Pole Magnetic World Circuit Breaker is a marine-grade electrical protection device rated for 25 amps, meeting all American Boat and Yacht Council (ABYC) standards for both AC and DC applications. This breaker is UL 1077 recognized, TUV certified, CE marked for European compliance, and CSA certified for Canada—making it the trusted standard for recreational and commercial vessel electrical systems worldwide.

The 25-amp rating with standard delay characteristics protects against both overloads and short circuits in AC/DC dual-voltage marine environments. The magnetic trip mechanism responds instantly to fault conditions, while the thermal overload element prevents nuisance tripping during normal inrush currents—critical for reliable performance when starting electric motors, windlasses, or other high-draw equipment. At 0.2 lbs and compact 3 x 1 x 4-inch dimensions, it integrates seamlessly into existing panel installations without requiring major rewiring or reconfiguration.

This breaker is designed for weekend fishermen upgrading older systems and serious offshore cruisers running complex electrical networks. Whether protecting dedicated circuits for battery chargers, navigation systems, cabin lighting, or auxiliary pumps, the World Circuit Breaker delivers predictable, code-compliant protection. Its dual-voltage capability makes it ideal for vessels with both 12/24-volt DC systems and 120/240-volt AC genset installations, eliminating the need for separate breaker types.

Blue Sea Systems' World Circuit Breaker has become the industry standard for new marine construction and retrofit work because it combines reliability with universal compliance—no special adapters or conditional approvals required. The 25-amp rating covers most individual circuit demands in small to mid-sized vessels, from battery bank management to thruster operation.
