Contura 12 V DC waterproof circuit breaker panel - White 8 positions

The BLUE SEA Contura 8-circuit breaker panel (part number 8271-BSS) has overall dimensions of 238.00 mm wide by 108.00 mm high (9-3/8 x 4-1/4 inches). Its depth is 69.90 mm (2-3/4 inches).

Yes, this display is designed to be waterproof. Its front face has IP66 certification, providing protection against powerful water jets, salt spray, rain, hose-downs, and brief immersions. It is suitable for deck-mounted applications.

The panel includes eight default 15 amp push-button circuit breakers. Each circuit breaker is protected by a waterproof cap, and each Contura ON-OFF switch is equipped with a power indicator LED.

The panel is constructed from 2.54 mm (0.100 inch) thick 5052-H32 aluminum. It undergoes chemical treatment per MIL-SPEC C-5541, followed by a two-part textured polyurethane finish in Arctic White. This build provides durability and corrosion resistance in marine environments.

Each LED power indicator, integrated in the switch, consumes 18 milliamps. These LEDs have an estimated lifespan of 100,000 hours at half-life.

The five main functions of this marine electrical panel are:

Power distribution.Protection of circuits (wires).ON/OFF switching of circuits.Indication of status (circuit under power).

The panel is supplied with a mounting gasket, mounting screws, and a selection of 60 basic circuit labels for customizing the identification of each switch.

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

For 12 Volt DC systems, the maximum capacity per switch and circuit breaker is 20 amperes. For 24 Volt DC systems, the maximum capacity is 15 amperes per switch and circuit breaker. The total cumulative capacity of the panel is 45 amperes.

No, this panel must not be installed in explosive environments such as gasoline engine rooms or battery compartments. The panel's switches are not spark-proof.

To ensure the front panel's water resistance, it must be properly sealed against the dashboard surface. The included gasket must be placed between the panel and the mounting surface, and the panel must be firmly screwed in. Ensure all surfaces are clean and free of debris.

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 unplug the AC power cord from the dock to prevent any risk of electrocution due to nearby AC wiring in the DC distribution panel.

The cutout template for panel 8271/8371 specifies a cutout of approximately 218.95 mm (8.620") in width and 108.46 mm (4.270") in height for the main section. The mounting centers are 216.90 mm x 86.90 mm (8-17/32 x 3-13/32 inches). It is recommended to use the provided template for precise cutting.

The positive power cable (red) must be sized based on the total amperage of the circuits routed through the panel. The panel's total cumulative capacity is 45 amperes. It is recommended to size the positive power cable for the panel's full capacity, which in most cases will require at least an 8 AWG wire for a 3% voltage drop over a 10-foot length in a 12-volt system. Refer to the wire sizing chart for other scenarios.

Each negative wire (yellow) of secondary circuits must be connected to a DC common ground bus (DC Negative Bus), such as a Blue Sea Systems PN 2301 busbar or MiniBus PN 2304.

A positive wire (red) from each secondary circuit must be connected to the charge terminal of the corresponding switch on the panel.

A set of 60 base labels is provided with the panel. Select the appropriate label for each circuit and apply it to the recessed area provided on the front face of the panel.

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

Yes, this Blue Sea Systems waterproof electrical distribution panel is designed to comply with the standards and recommended practices of the American Boat and Yacht Council (ABYC) for small boats (section E-9), as well as with the United States Code of Federal Regulations 33, Part 183, Subpart I, regarding electrical systems on boats.
