DESCRIPTION
Blue Sea Systems 4376 Waterproof 6-Position Circuit Breaker Switch Panel
Heavy-Duty IP67 Marine Electrical Protection for 12V and 24V DC Systems
Managing electrical circuits in exposed marine and off-road environments requires hardware engineered to withstand constant moisture, salt spray, and vibration. The Blue Sea Systems 4376 WeatherDeck Waterproof Circuit Breaker Panel is purpose-built for open-cockpit boats, flybridges, and rugged 4WD setups. While the unit is commonly sought after for 12V DC systems, it is fully rated and compatible with 24V DC electrical architectures, providing versatile power distribution across a wide range of recreational and commercial applications.
Standard interior switch panels quickly succumb to corrosion and short circuits when exposed to the elements. This 6-position circuit breaker panel eliminates those failure points by combining UV-stabilised, waterproof switch boots with a rugged reinforced polycarbonate faceplate. Rated to IP67 for temporary immersion up to 30 minutes, it provides dependable circuit protection and switching control even when mounted in direct weather zones.
Integrated Circuit Protection and Independent Backlighting
Rather than relying on separate fuse blocks tucked away behind the helm or dashboard, this panel integrates push-to-reset thermal circuit breakers directly alongside each toggle switch. Each individual circuit supports up to 15A at 12V DC (or 9A at 24V DC), with a cumulative panel rating of 45A, allowing you to safely manage high-draw accessories like bilge pumps, navigation lights, VHF radios, and deck floodlights.
Night-time operation requires clear visibility that does not compromise the operator's night vision. This panel features integrated green LED backlighting across all six label positions. Because the backlighting circuit is independent of the switch positions, all labels remain clearly illuminated whenever the panel receives power. Furthermore, the lighting system is compatible with Blue Sea Systems Digital Dimmers, enabling precise brightness control to suit changing ambient light conditions.
- IP67 Waterproof Rating: Engineered to withstand temporary water immersion for up to 30 minutes, ideal for exposed marine helms and open cockpits.
- Dual Voltage Compatibility: Suitable for both 12V DC and 24V DC applications, expanding its utility across marine, caravan, and heavy vehicle platforms.
- Integrated Push-to-Reset Breakers: Six individual thermal circuit breakers with protective watertight boots eliminate the need for replacement fuses on the water.
- Multi-Orientation Mounting: Designed to be installed in four different orientations (vertical or horizontal) to accommodate tight dashboard layouts.
- Reinforced Polycarbonate Housing: Impact-resistant, UV-stabilised grey faceplate prevents corrosion and structural degradation in harsh Australian sun and salt environments.
- Low-Light Readability: Independent green LED backlit labels consume just 10mA per illuminated circuit and support external dimming control.
Versatile Installation for Marine and Off-Grid Applications
Space at the helm or in a custom canopy is often restricted. To simplify installation, the Blue Sea 4376 panel is designed to be mounted in four distinct orientations, giving system builders the flexibility to align the switches vertically or horizontally. Its tough construction makes it an exceptional upgrade for:
- Centre console boats, RIBs, and flybridge cruisers
- Kayak and tinny electrical distribution boxes
- 4WD canopy power setups exposed to dust and water crossings
- Camper trailers and external caravan control panels
- Industrial and agricultural machinery with open cabs
