Blue Sea 7149 200 Amp Circuit Breaker - Surface Mount

The Blue Sea 7149 200 Amp Circuit Breaker – Surface Mount is the backbone of reliable electrical protection on any vessel, whether you're running a center console, cruiser, or commercial fishing boat. This dual-purpose device combines switching and circuit protection into a single, compact unit, eliminating the need for separate components and reducing panel clutter. Built for the demanding marine environment, it delivers the dependable fault protection serious boaters demand when hours on the water depend on consistent electrical performance.

The 200 amp rating handles substantial electrical loads—from thruster systems and battery banks to multiple engine compartment loads—without nuisance tripping. Its trip-free design prevents the lever from being held in the ON position during a fault condition, a critical safety feature that ensures automatic shutdown when current exceeds safe limits. The waterproof construction stands up to salt spray, washdowns, and the corrosive marine environment, while the recessed mounting holes protect terminals and simplify secure installation on cabin bulkheads or electrical panels. Clear, intuitive single-lever operation means any crew member can quickly identify system status and manually disconnect circuits when needed.

This breaker suits boat owners upgrading aging electrical systems, installing new DC distribution panels, or adding high-draw accessories like electric winches and bow thrusters. Its compact footprint (5 x 2 x 9 inches) fits tight spaces common in helm stations and engine rooms, making it ideal for retrofit work where panel real estate is limited. Professional captains and marine electricians routinely specify Blue Sea breakers for their reputation and reliability—performance you can count on when you're miles offshore and the nearest service station is a radio call away.
