Blue Sea 7250 C-Series Toggle Single Pole - 100A

The Blue Sea 7250 C-Series Toggle Single Pole 100A marine circuit breaker is the backbone of reliable electrical protection for serious boaters and anglers who depend on their vessels. Whether you're running a bow thruster on a center console, powering a windlass on a cruiser, or protecting an inverter system on a cabin cruiser, this single-pole toggle breaker delivers the switching and overcurrent protection your marine electrical system demands. Built by Blue Sea Systems—the trusted name in marine electrical safety for decades—this breaker combines switching convenience with circuit protection in one compact, time-tested design.

The C-Series toggle mechanism features a manual on/off switch paired with automatic overcurrent protection rated for 100 amperes, making it ideal for high-draw marine applications where equipment failure isn't an option. The white finish is standard across Blue Sea's C-Series lineup, ensuring professional appearance and easy identification in engine rooms and electrical panels. At just 0.6 pounds and measuring a compact 3 x 3 x 5 inches, this breaker integrates seamlessly into tight panel spaces without sacrificing durability or switching speed. The single-pole configuration handles one circuit independently, allowing you to protect critical systems individually while maintaining fast, reliable response to electrical faults.

Captains and boat owners planning electrical upgrades or panel replacements will appreciate the Blue Sea 7250's versatility across 12V and 24V marine systems. Installation into standard marine electrical panels is straightforward for those familiar with basic boat wiring; however, professional installation is always recommended for high-amperage circuits. This breaker pairs well with battery banks, inverter systems, and powered accessories common on fishing boats, cruisers, and commercial vessels. If you're upgrading from older fuses or inferior breakers, the 7250 delivers the consistent, automatic protection that lets you fish or cruise with confidence.
