Blue Sea 285-Series 120 Amp Circuit Breaker Surface Mount

The Blue Sea 285-Series 120 Amp Circuit Breaker Surface Mount is the marine electrical protection standard trusted by experienced boaters and fishing professionals who demand reliability in harsh saltwater and freshwater environments. This ignition-protected breaker is engineered specifically for gasoline-powered vessels, where electrical safety isn't negotiable—one catastrophic fault can mean the difference between a safe return to port and a serious onboard emergency. Whether you're running a center console, trawler, or dedicated fishing platform, this surface-mount unit provides the automatic overload protection your boat's main electrical system demands.

Built on the proven 285-Series platform, this 120-amp breaker features a visible reset lever that instantly shows open condition—critical when diagnosing electrical faults at sea where you cannot afford guesswork. The surface-mount design allows installation directly onto bulkheads or panels without requiring expensive custom enclosure modifications, saving both time and money during retrofit or new-build projects. Ignition protection certification ensures safe installation aboard gasoline-powered craft, meeting ABYC standards for marine electrical systems. The unit operates as a direct drop-in replacement for older 185-Series breakers, making upgrades straightforward for vessels already equipped with legacy systems.

This breaker is ideal for anglers, cruisers, and professional mariners protecting main battery banks, primary engine circuits, or large-load systems like bow thrusters and hydraulic winches. Weighing only 0.5 pounds, it integrates seamlessly into tight engine compartments and electrical enclosures where space is limited. Any boater serious about vessel safety and compliance with modern marine electrical codes should standardize on Blue Sea Systems circuit protection—proven performance across thousands of installations in commercial and recreational fleets worldwide.
