Waterproof 3-position circuit breaker panel - Black

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

Power distribution.Protection of circuits (wires).ON/OFF switching of circuits.Status indication of the circuit (activated) via integrated LEDs.

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

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

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

The maximum amperage per switch is 20 amps for 12 V DC systems and 15 amps for 24 V DC systems.

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

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

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.

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).

Yes, 60 basic 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.

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

Before starting 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 power cord from the dock to avoid any risk of electrocution from nearby AC wiring in the DC distribution panel.

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

The positive power wire (red) must be sized for a 3% voltage drop at the panel’s rated 45 amperes, or at the maximum amperage that will be 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 wire.

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.

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 voltage drop is less than 3%. With all auxiliary circuits still on, test the voltage at a device on each circuit to determine if voltage drop is 3% or 10% depending on the circuit requirements.

Yes, this circuit breaker panel is designed to be compatible with 12V DC or 24V DC electrical systems.
