Detailed description

Designed for demanding marine environments, the BLUE SEA 3-position waterproof circuit breaker panel (part number 8374-BSS) provides a compact and secure electrical distribution solution. Ideal for installations on flybridges, in cockpits, or any other area exposed to the elements, this panel resists salt spray, rain, and hose-downs with IP66 protection.

Design and Technical Specifications

This panel integrates three Contura ON-OFF rocker switches, each equipped with a status LED for clear circuit state visualization. Each switch is paired with a push-to-reset circuit breaker with a waterproof cap, ensuring reliable protection. The maximum capacity per switch is 20A for 12V DC systems and 15A for 24V DC systems, with a total capacity of 45A for the entire panel. This configuration is suitable for auxiliary circuits or simpler electrical systems, distinguishing it from larger main distribution panels, such as BLUE SEA’s 6- or 12-position models, which manage a greater number of loads.

Materials and Durability

The panel is constructed from 2.54 mm (0.100 inch) thick 5052-H32 aluminum alloy, chemically treated to military specification C-5541. The finish consists of a two-part textured black polyurethane coating, UV-stabilized and corrosion-resistant. Its compact dimensions of 95.25 mm (3.75") height x 114.3 mm (4.50") width x 82.55 mm (3.25") depth, combined with a lightweight of approximately 0.34 kg (0.75 lb), facilitate installation in tight spaces. Additionally, it is certified compliant with CE, IP66, ISO 8846, and UL 1500 standards, and is ignition-protected per SAE J1171, making it safe for gasoline-powered boats.

« Technical analysis of BLUE SEA 3-position waterproof panel for auxiliary circuits »

The BLUE SEA 3-position waterproof circuit breaker panel is a suitable solution for installations where space is limited or for adding dedicated circuits to existing boats. Its compact design and IP66 water resistance make it particularly well-suited for open-console boats, rigid inflatables, or sailboats requiring auxiliary electrical distribution on deck. It allows management of specific loads such as navigation lighting, a secondary bilge pump, or weather-exposed electronic equipment.

The main advantage of this panel is its ignition-protected design, a critical safety feature for gasoline-powered boats, enabling worry-free installation in engine compartments or areas prone to flammable vapors. Installation is simplified by its pre-wired design and included sealing gasket, ensuring clean and reliable integration on the mounting surface. It is important to note that, while robust, this panel is designed for low-circuit systems and does not replace a main distribution panel for complex installations requiring numerous outputs or advanced monitoring functions. It excels in managing isolated circuits, providing reliable protection and accessibility.

Frequently Asked Questions

Need help? Contact us

What is the main function of this Blue Sea circuit breaker panel?

The Blue Sea 3-position waterproof circuit breaker panel serves several essential functions in a marine electrical system:

Power distribution.Circuit protection (wires).ON/OFF switching of circuits.Circuit status indication (activated) via built-in LEDs.

Is the panel water-resistant?

Yes, this panel is designed to be water-resistant and can withstand conditions typically encountered on deck. This includes salt spray, rain, hose-downs, and brief immersions. It provides IP66 protection.

How many circuit breakers does this breaker panel have?

The panel is equipped with three Contura ON-OFF rocker switches.

Are there indicators for the circuits?

Yes, each switch includes a power indicator LED. These LEDs are rated for a lifespan of 100,000 hours (at half-life), providing clear visibility of the circuit status.

What is the maximum amperage per switch?

Maximum capacity per switch is 20 amperes for 12-volt DC systems and 15 amperes for 24-volt DC systems.

What is the total cumulative capacity of the panel?

The total combined capacity for the entire panel is 45 amperes.

What material is the panel made of?

The panel is made from a 5052-H32 aluminum alloy with a thickness of 2.54 mm (0.100 inch).

What is the finish of the panel?

The panel finish is ensured by a chemical treatment compliant with military specification C-5541. It is then coated with a two-part textured black polyurethane finish, UV-stabilized and corrosion-resistant.

What are the physical dimensions of this panel?

The overall dimensions of the panel are 114.30 mm (4-1/2 inches) in height by 95.25 mm (3-3/4 inches) in width. The panel depth is 69.90 mm (2-3/4 inches).

Is the panel supplied with circuit labels?

Yes, 60 base circuit labels are supplied with the panel. They can be applied to the recessed area at the front of the panel to clearly identify each circuit.

Where can I install this circuit breaker panel?

This panel is designed to be installed in water-exposed locations such as flybridges, cockpits, or other deck areas. It must not be installed in explosive environments like gasoline engine rooms or battery compartments, as the switches are not protected against ignition.

What precautions should I take before installing the panel?

Before starting the installation, it is crucial to take the following precautions:

Disconnect the main positive cable from all batteries to eliminate any risk of short circuit. Unplug the AC shore power cord to avoid electrocution risk from AC wiring near the DC distribution panel.

How to ensure the panel's watertightness during installation?

A sealing gasket is included with the panel to ensure it is watertight against the mounting surface. The gasket must be placed between the panel and the mounting surface, and the panel must be firmly secured using the supplied mounting screws. Ensure all surfaces are clean and free of debris.

Which type of wire should I use for the main positive power feed to the panel?

The positive power cable (red) must be sized for a 3% voltage drop at the panel’s rated 45 amperes, or at the maximum amperage carried in your specific installation, whichever is lower. For full panel capacity, an 8 AWG wire is typically recommended for a 10-foot run in a 12-volt system. It is essential that an appropriately sized fuse or circuit breaker protects this positive power cable.

How to connect wires in auxiliary circuits (branch circuits)?

For auxiliary circuits:

Connect the positive wire (red) of each circuit to the charge terminal of the corresponding switch. Connect the negative wire (yellow) of each circuit to a DC negative bus, such as a Blue Sea Systems PN 2301 BusBar PN or MiniBus PN 2304.

How to check the installation after mounting the panel?

After reconnecting the main positive cable to the battery and turning on the main switch to power the panel:

Turn on all auxiliary circuits and test the voltage at the panel. Compare this voltage to the voltage at the battery terminals to ensure the voltage drop is less than 3%. With all auxiliary circuits still on, test the voltage at a device on each circuit to determine if the voltage drop is 3% or 10% depending on the circuit requirements.
