Blue Sea Systems

Blue Sea Systems is the gold standard for marine electrical power management and distribution. Founded on the principle of improving the safety and reliability of onboard electrical systems, their products are designed to meet or exceed ABYC, NMMA, and USCG standards.

At Anchor Express, we offer the comprehensive Blue Sea Systems catalog, specializing in everything from simple fuse blocks to complex, integrated Custom 360 Panels.

1. Battery Management & Switching

Blue Sea Systems is world-renowned for their "Add-A-Battery" kits and intelligent charging relays that protect your starting batteries from being drained by house loads.

• m-Series Battery Switches: The industry standard for small to medium boats. Available in Single Circuit, Selector, and the popular Dual Circuit Plus™, which allows you to turn both the Start and House batteries on with a single knob while keeping them isolated.

• Automatic Charging Relays (ACR): These "smart" relays automatically combine battery banks for charging from a single source (like an alternator) and isolate them when discharging or starting the engine.

• ML-Series Remote Switches: Designed for large offshore yachts, these allow you to switch high-amp battery banks from the helm using a small remote switch, reducing long, heavy cable runs.

2. Circuit Protection & Safety

Every wire on a boat requires protection. Blue Sea Systems provides the most reliable breakers and fuses to prevent electrical fires.

• ST-Blade Fuse Blocks: The #1 choice for organizing electronics wiring. They feature a clear insulating cover and integrated label circuits, available with or without a common negative bus.

• A-Series & C-Series Circuit Breakers: Found in almost every high-end marine electrical panel. These "Trip-Free" magnetic-hydraulic breakers can be used for both AC and DC applications and won't trip due to high ambient engine room heat.

• SafetyHub Fuse Blocks: Ignition-protected blocks designed to reside near the battery or in engine compartments, consolidating high-amp and 24-hour circuits into one safe location.

3. Power Distribution & Custom 360 Panels

The 360 Panel System is a modular architecture that allows boaters to create a professional-grade distribution center.

• Stock 360 Panels: We carry pre-configured panels for 12V DC branch circuits, AC mains, and combination AC/DC systems, often featuring integrated USB charging and OLED monitoring.

• Custom 360 Panels: Through Anchor Express, you can order bespoke panels featuring a mix of rockers, digital meters (M2 Series), and even ELCI (Leakage Current) protection to meet modern safety codes.

• BusBars & Connectors: High-conductivity tinned copper busbars (like the MaxiBus 250A) provide a secure and organized way to manage multiple ground and positive connections.
