The BLUE SEA 3-position DC distribution panel is designed for managing and protecting electrical circuits on board. Its primary functions include power distribution, cable protection (circuits), on/off switching of circuits, and indicating their status (live circuit).

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

The panel has a slate gray color. It has a primary chemical treatment compliant with military specification C-5541C, followed by a textured polyurethane topcoat in graphite color.

Yes, this panel is designed to withstand typical above-deck water exposures. This includes salt spray, rain, hose-downs, and momentary immersions.

The overall dimensions of the panel are 133.40 x 95.30 mm (5-1/4 x 3-3/4 inches).

The BLUE SEA 3-position distribution panel is designed to manage three separate circuits.

The fuse holders on this panel accept commonly available 1-1/4" x 1/4" AGC (fast-acting) and MDL (slow-blow) glass fuses.

Yes, the panel is shipped with pre-installed 15-amp AGC (fast-acting) fuses for each circuit.

Each circuit is fitted with an LED indicator integrated into the switch. This LED lights up when the circuit is live, with a nominal lifespan of 100,000 hours at half-life.

Yes, it is important to select a mounting location that is not an area where flammable vapors (from propane, gasoline, or lead-acid batteries) could accumulate. This panel is not protected against ignition and could ignite such vapors.

The panel must be mounted on a surface cut using the provided template. Once the opening is made, the included sealing gasket must be placed between the panel and the mounting surface. Then, the panel is firmly screwed to the surface using the provided mounting screws, after ensuring all surfaces are clean and free of debris.

The main positive power feed cable (red) must be sized for a 3% voltage drop at the panel’s full 45-amp capacity, or at the maximum amperage that will be routed through the panel if lower. It is recommended to size the cable for the panel’s full capacity, which in most cases will require at least an 8 AWG cable for a 12-volt system with a 3-meter (10-foot) cable run between the panel and the batteries. It is essential to protect this cable with a properly sized fuse or circuit breaker.

A 16 AWG wire must be used to connect the negative LED power cable (yellow) to the DC negative bus, such as a Blue Sea Systems MiniBus PN 2304.

Yes, the panel is supplied with 30 basic circuit labels. They can be applied to the recessed area at the front of the panel. An extended 120-label set (PN 8039) can be ordered separately if the required labels are not found.

Yes, before starting the installation, it is imperative to disconnect the main positive cable from all batteries to eliminate any risk of short-circuit. You must also disconnect the AC shore power cord from the boat to avoid any risk of electrocution due to nearby AC wiring in the DC distribution panel.

The total cumulative capacity of this distribution panel is 45 amperes.

Yes, this distribution panel is designed to operate with 12-volt or 24-volt DC electrical systems.

For a 12-volt system, the maximum rating for each switch and fuse holder is 20 amperes.

For a 24-volt system, the maximum rating for each switch and fuse holder is 15 amperes.

Any Blue Sea Systems product that a customer is not satisfied with can be returned for a refund or replacement at any time.
