Blue Sea Systems AC Main Only Circuit Breaker Panel, 120/240V, 50A, 3-Pole

Overview

The Blue Sea Systems 7372 is a 120/240V AC main panel with a factory-installed 50A C-Series triple-pole breaker. It is a main-only panel for boats that need a dedicated AC disconnect at the head of the shore-power system, with a compact 5.25 in x 3.75 in face size and about 3.00 in of depth behind the panel.

This panel includes the neutral and safety ground buses, along with pre-installed LEDs and backlit circuit labels. The reverse-polarity indicator gives a quick visual check during hookup and commissioning, which is especially useful when a boat moves between marinas or shore-power sources.

For refits and replacement work, this is the kind of panel that makes sense when branch circuits are handled elsewhere and the job is to add or replace the AC main breaker section without taking up much dash or cabinet space.

Key features

• 120/240V AC main-only panel with a 50A triple-pole C-Series breaker already installed
• Red reverse-polarity LED gives a clear warning if incoming AC is wired incorrectly
• Neutral and safety ground buses are already fitted, which helps keep AC wiring organized
• Backlit labels and installed LEDs make the panel easier to read in darker cabins, lockers, and utility spaces
• Traditional metal panel layout with a compact 5.25 in x 3.75 in front face and about 3.00 in mounting depth

Compatibility and fit

This panel is intended for 120/240V AC shore-power systems that use a 50A main breaker. The triple-pole layout fits applications where split-phase AC service is being brought aboard, so the panel should be matched to the boat's shore inlet, cordset, source selection, and downstream branch protection.

Because it is a main-only panel, it suits installations where the branch breakers are on a separate panel or where the boat needs a compact AC main section added to an existing electrical layout.

Installation and setup

On board, this panel is usually mounted in an accessible interior location near the point where shore power enters the AC distribution system. The installed neutral and safety ground buses reduce extra setup work, and the small face size helps when replacing an older panel in a tight helm, cabin bulkhead, or electrical cabinet.

Rear clearance matters on this model, so it is worth checking available depth before ordering for a retrofit. The reverse-polarity indicator and pre-installed lighting also make post-install checks easier when the boat is first connected to dock power.

Use on board

This panel is a sensible match for cruisers, sailboats, and smaller yachts that need a straightforward AC main breaker section without combining branch circuits into the same panel. It also fits refit projects where the original main panel is tired, damaged, or no longer matches the rest of the AC system layout.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
