Detailed description

Designed for the most demanding marine environments, the BLUE SEA 6-position water-resistant circuit breaker panel (reference 8373-BSS) provides a reliable and secure electrical distribution solution. With IP66 certification, this panel is specifically suited for installation on flybridges, open cockpits, and other areas exposed to spray, rain, and water washing, ensuring protection against powerful water jets. Its design allows it to withstand temporary immersion, which is critical for the safety of onboard electrical systems.

Design and Technical Specifications

The BLUE SEA 8373-BSS panel is rated for operation at 12V or 24V DC, with a maximum cumulative capacity of 45 amperes. Each circuit is equipped with a 15A push-button circuit breaker, with switches rated at a maximum of 20A for 12V systems and 15A for 24V systems, featuring sealed caps for enhanced protection. The ON-OFF Contura-type switches include illuminated LED indicators, making it easier to identify active circuits even in low-light conditions. The panel is made from 2.54 mm thick 5052-H32 aluminum alloy, UV-stabilized, fire-retardant, and corrosion-resistant, with a textured black polyurethane finish.

Installation and Compliance

This panel is designed for vertical mounting and includes a sealing gasket to ensure a watertight connection with the mounting surface, preventing water infiltration behind the dashboard. Wiring is simplified with 6.35 mm quick-connect terminals for the circuit breakers and a two-wire connection for the panel’s main power supply. The panel’s overall dimensions are approximately 190.50 mm (H) x 114.30 mm (W) x 82.55 mm (D). It is supplied with a set of 60 labels for circuit customization. The BLUE SEA 8373-BSS panel is CE, ISO 8846, and UL 1500 certified, ensuring compliance with international maritime standards. Unlike unprotected panels that are not ignition-proof, this model is safe for installation on gasoline-powered boats.

« Marine circuit protection: expert review of the BLUE SEA waterproof IP66 panel »

The BLUE SEA 6-circuit waterproof circuit breaker panel (8373-BSS) is an essential electrical solution for vessels requiring reliable power distribution in exposed areas. Its IP66 protection rating is a major advantage, setting it apart from standard panels designed for indoor installations. This feature makes it particularly suitable for flybridges, open helm stations, and cockpits, where constant exposure to spray and weather is a factor. The flame-retardant design is also a significant safety factor for boats equipped with gasoline engines, reducing the risk of vapor ignition.

In terms of installation, this panel is relatively straightforward thanks to its quick-connect terminals and the supplied sealing gasket, which is critical for maintaining IP66 protection integrity. It is essential to properly size the power and branch cables, taking into account the panel’s maximum cumulative load of 45A, to avoid overloading and comply with ABYC standards. This model is ideal for secondary distribution of medium-power circuits, such as lighting, bilge pumps, or auxiliary navigation electronics. It should not be used for high-intensity loads requiring primary battery circuit breakers.

Frequently Asked Questions

Need help? Contact us

What are the dimensions of this Blue Sea 6-circuit breaker panel?

The Blue Sea 6-circuit breaker panel (PN 8373) has overall dimensions of 114.30 x 190.50 mm (4-1/2 x 7-1/2 inches).

Is this circuit breaker panel waterproof?

Yes, this panel is designed to be water-resistant. It can withstand water exposure typically encountered on deck, such as salt spray, rain, hose-downs, and brief immersions. The detailed description mentions IP66 certification.

How many circuits can this panel handle?

This circuit breaker panel is a 6-position model, meaning it can handle six distinct electrical circuits.

What is the manufacturing material of this circuit breaker panel?

The panel is made from 5052-H32 aluminum alloy, 2.54 mm (0.100") thick. It is UV-stabilized, fire-resistant, and corrosion-resistant, with a textured black polyurethane finish.

What is the operating voltage of this panel?

This panel is designed to operate with 12 V or 24 V DC electrical systems.

What is the maximum cumulative current capacity of this panel?

The maximum cumulative current capacity of this circuit breaker panel is 45 amperes.

What types of circuit breakers are included and what are their ratings?

Each circuit is equipped with standard 15-amp push-button circuit breakers. The maximum capacity for switches and circuit breakers is 20 amps for 12-volt systems and 15 amps for 24-volt systems.

Are the switches on this panel illuminated?

Yes, the ON-OFF Contura-style switches include built-in LED lights. These LEDs have a nominal lifespan of 100,000 hours at half-life.

What is the color and finish of this circuit breaker panel?

The panel has a textured black polyurethane finish.

What is the panel’s cutout depth?

The panel’s cutout depth is 69.90 mm (2-3/4 inches).

Can this circuit breaker panel be mounted horizontally?

No, this panel is designed for vertical mounting only.

What safety precautions should I take before installing the panel?

Before starting the installation, it is imperative to disconnect the main positive cable from all batteries and unplug the AC power cord from the boat’s shore power to eliminate any risk of short-circuit or electric shock.

Is a sealing gasket included with the panel for installation?

Yes, a sealing gasket is included to ensure a watertight connection between the panel and the mounting surface. It must be installed and the panel screwed firmly in place.

How to choose the correct wire gauge for the panel's positive power feed?

The positive power wire (red) must be sized for a 3% voltage drop at the panel's rated capacity of 45 amps, or at the maximum amperage that will be carried by the panel, whichever is lower. It is recommended to size the wire for the panel's full capacity, which in most cases will require at least an 8 AWG wire for a 10-foot run between the panel and batteries in a 12-volt system.

How to connect wires in branch circuits?

The positive wire (red) of each branch circuit must be connected to the load terminal of the corresponding switch. The negative wire (yellow) of each branch circuit must be connected to a DC negative bus, such as a Blue Sea Systems PN 2301 BusBar or MiniBus PN 2304.

Are labels for the circuits provided with the panel?

Yes, 60 base labels are provided for branch circuits, to be applied on the recessed area at the front of the panel.

How to ensure the panel remains watertight after installation?

To ensure watertightness, the supplied gasket must be correctly positioned between the panel and the mounting surface. All surfaces must be clean and free of debris. The panel must then be firmly screwed down using the supplied mounting screws.
