Blue Sea 4374 WeatherDeck Water Resistant Circuit Breaker Panel - 4 Position - Grey

The Blue Sea 4374 WeatherDeck Water Resistant Circuit Breaker Panel is purpose-built for serious boaters who demand reliable electrical protection in harsh marine environments. Whether you're running a flybridge cruiser, open center console, or any vessel exposed to salt spray and heavy weather, this four-position panel delivers the dependable circuit isolation that keeps your onboard systems running safely when conditions get rough. After years on the water, you know that electrical failures can strand you miles from help—this panel eliminates that risk with proven marine-grade engineering.

Built to IP67 standards with temporary immersion rating for up to 30 minutes, the WeatherDeck panel withstands direct spray, washdown, and brief submersion without compromising circuit protection. The grey composite housing resists UV degradation and corrosion, while the four individual circuit breaker positions allow independent control of critical loads—batteries, nav systems, bilge pumps, and auxiliary circuits. Each breaker trips instantly on overcurrent, protecting wiring and equipment from shorts or overloads that could trigger fires or electrical damage. The compact 6 x 6 x 8-inch footprint fits tight companionway spaces and console corners where traditional enclosures won't mount.

This panel is ideal for retrofit installations on older boats and new builds alike, particularly those with open upper decks where standard electrical cabinets face constant weather exposure. Anglers, cruisers, and commercial operators rely on Blue Sea circuit management to keep engines, lighting, and safety systems online during extended trips. Installation requires basic marine wiring knowledge and 12V or 24V DC systems; consult your boat's electrical schematic for proper breaker rating selection. The WeatherDeck 4374 is the go-to upgrade when stock panels fail or prove inadequate for modern electronics and demand.
