Blue Sea Systems WeatherDeck Waterproof Circuit Breaker Panel, 12/24V DC, IP67, 15A Per Circuit, Green LED Backlit Labels, Gray Panel

Overview

The Blue Sea Systems WeatherDeck Circuit Breaker Panel is a gray waterproof DC circuit breaker panel for 12V and 24V boat electrical systems. It combines switching, circuit protection, and backlit labeling in one panel, making it a practical fit for exposed helm stations, flybridges, open cockpits, and other areas where spray, rain, and washdowns are part of normal use.

The panel is IP67 rated for temporary immersion up to 30 minutes and uses a reinforced polycarbonate body. Each circuit is protected by a circuit breaker rated up to 15A at 12V DC or 9A at 24V DC, with a 45A cumulative panel rating. Green LED label backlighting helps keep circuit labels readable at night, and the labels illuminate when the panel is powered regardless of individual switch position.

Key features

• Waterproof IP67 rating supports installation in exposed marine locations where rain, spray, and cockpit washdowns are expected.
• Works with 12V DC and 24V DC systems, with backlighting that also supports 12V or 24V DC supply.
• Circuit breaker protection is built into each position, reducing the need for separate branch circuit breakers behind the panel.
• Green LED label backlighting draws 10mA per illuminated circuit and helps identify circuits in low light.
• Compatible with Blue Sea Systems Digital Dimmers for installations where label lighting brightness is controlled from the helm or panel area.
• Mounts in four different orientations, which helps when space is tight or the panel must align with an existing helm layout.
• Reinforced polycarbonate construction gives the panel a body suited to saltwater use, vibration, and UV-exposed mounting areas.

Variants

This WeatherDeck circuit breaker panel is offered in three position counts so the panel can match the number of DC circuits being controlled from the same location.

The main difference between the variants is the number of circuit positions and the panel height. The voltage rating, circuit breaker protection, 45A cumulative panel rating, green LED label backlighting, 4.25 in width, and 3.50 in depth remain consistent across the listed versions.

• 4374 has 4 positions. This is the shortest version at 4.30 in high, useful for a small group of switched DC loads where panel space is limited.
• 4376 has 6 positions. This version is 6.00 in high and suits a medium helm or cockpit switching group without moving to the taller panel.
• 4378 has 8 positions. This version is 7.70 in high and gives more circuit control in one WeatherDeck panel while keeping the same width and depth as the smaller versions.

Installation and fit

Use the selected position count to confirm both circuit capacity and panel space before cutting or replacing an existing panel. All three variants share the same 4.25 in width and 3.50 in depth, while the height changes with the number of positions. The 4-position panel is 4.30 in high, the 6-position panel is 6.00 in high, and the 8-position panel is 7.70 in high.

The four-orientation mounting option is helpful on consoles and flybridge panels where wiring access, label direction, or nearby electronics may limit the normal mounting position. The panel is a good match for boats that need DC circuit control in areas that are not fully enclosed.

Electrical and system integration

Each circuit supports up to 15A at 12V DC or 9A at 24V DC, and the total panel load should stay within the 45A cumulative rating. Match each connected load, wire size, and overcurrent protection plan to the vessel electrical layout before installation.

The built-in green LED label backlighting makes the panel easier to read on evening runs, night fishing, or dockside checks after dark. Compatibility with Blue Sea Systems Digital Dimmers also helps when the panel is installed near navigation displays or other helm electronics where lighting level matters.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
