Blue Sea Systems: Excellence in Marine Electrical Systems
Blue Sea Systems, an American manufacturer established in 1986 and based in Bellingham, Washington, is a global leader in marine electrical equipment. Specializing in electrical distribution systems, circuit breaker protection, battery disconnect switches, and control panels, Blue Sea Systems equips everything from luxury yachts to professional workboats and offshore racing sailboats. The brand is renowned for its exceptional manufacturing quality, rigorous compliance with ABYC (American Boat and Yacht Council) and ISO standards, and detailed technical documentation that facilitates installation and maintenance. Skysat understands the critical importance of reliable and safe electrical distribution on board, and we offer our expertise to design and integrate robust, scalable, and perfectly sized Blue Sea Systems electrical systems.
Circuit Breakers and Electrical Protection
Blue Sea Systems circuit breakers are the heart of onboard electrical protection, providing fast and reliable interruption in the event of an overload or short circuit. Unlike traditional fuses, circuit breakers are resettable, simplifying maintenance and reducing downtime. The Blue Sea Systems range covers all the current requirements onboard, from small electronic equipment to high-power circuits such as bow thrusters and windlasses.
- 7000 Series (Thermal Circuit Breakers): Compact and robust thermal circuit breakers, available from 5A to 100A. Thermal and magnetic protection, UL 1077 certified and ABYC compliant. DIN rail or direct mounting, silver contacts for low resistance.
- A-Series Toggle Circuit Breakers: Thermal circuit breakers with integrated toggle switch, ideal for control panels. Available from 5A to 50A, compact design, IP56 protection against water splashes.
- C-Series Toggle Circuit Breakers (Magneto-Hydraulic Circuit Breakers): High-performance circuit breakers with magneto-hydraulic tripping, minimizing false tripping due to inrush currents. Available from 5A to 100A, ideal for equipment with high starting current peaks (compressors, electric motors).
- Series 187 Push-Button (Push-Button Circuit Breakers): Thermal circuit breakers in a push-button format, for front panel mounting. Optimal ergonomics, easy reset, available from 5A to 50A.
Circuit breakers and battery switches
Blue Sea Systems battery disconnect switches allow for the electrical isolation of batteries for maintenance, winter storage, or in emergencies. Essential for onboard safety, they also provide a robust connection point for heavy-gauge battery cables. The Blue Sea Systems range offers solutions for all configurations, from simple ON/OFF disconnect switches to complex multi-bank switches with parallel combination.
- m-Series (Mini Battery Switches): Compact circuit breakers for continuous currents up to 300A (600A starting current). Screw connections, IP67 waterproof housing, ideal for compact installations or auxiliary batteries.
- e-Series (Battery Switches): Robust circuit breakers for continuous currents up to 500A (2500A starting current). Silver-plated contacts, compression terminals, choice of ON/OFF or 1-BOTH-2-OFF selector models for multi-bank management.
- HD Series (Heavy Duty Battery Switches): High-power circuit breakers for professional applications, up to 600A continuous. Reinforced construction, solid silver contacts, certified for extreme marine applications.
- ACR (Automatic Charging Relays): Automatic charging relay for intelligent management of multiple battery banks. Enables simultaneous charging of engine and auxiliary batteries without risk of mutual discharge. Integration with modern chargers and alternators.
- ML-Series (Remote Battery Switches): Remotely controlled, solenoid-operated battery disconnect switches. Allows installation of the switch directly on the batteries (engine compartment) with remote control from the dashboard. Optimal safety and simplified wiring.
Distribution Busbars and Electrical Panels
Blue Sea Systems bus bars and electrical panels allow you to organize and streamline electrical distribution on board. By grouping common connections (ground, positive, fuse circuits), they simplify installation, improve reliability, and facilitate troubleshooting. Blue Sea Systems offers modular and scalable solutions for all vessel sizes.
- Common Bus Bars: Distribution bars for grouping common connections (ground or positive). Available in various sizes (6, 12, 20, 30 connections), nickel-plated copper construction, fully electrically insulated, simplified installation.
- SafetyHub (Fuse Distribution Hubs): Distribution busbars integrating individual fuse holders for each circuit. Available in 100A or 150A input versions, with 4 or 6 output circuits. ATO/ATC fuse protection, transparent protective covers, and blown fuse indicator LEDs.
- 360 Panels (Control Panels): Prefabricated electrical panels combining circuit breakers, a digital voltmeter, and circuit monitoring. Available in 4, 6, 8, or 12 circuit versions. Flush mounting, anodized aluminum finish, IP66 rating.
- Custom Panels: Blue Sea Systems also offers custom electrical panels, assembled to the exact specifications of the project. Ideal for commercial vessels or complex refits.
Fuse Holders and Fuse Blocks
Blue Sea Systems fuse holders provide individual protection for each electrical circuit on board. Available in numerous sizes (ANL, MIDI, MEGA, ATO/ATC), they allow for precisely sized protection for each piece of equipment. The watertight construction and high-quality materials ensure long-term reliability in corrosive marine environments.
- ANL Series Fuse Blocks: Fuse holders for ANL (high power) fuses, covering currents from 35A to 750A. Ideal for main circuits, inverters, thrusters, and windlasses. Compression connections, fully insulated housing.
- MEGA/MIDI Series Fuse Blocks: Fuse holders for MEGA and MIDI formats (medium to high current ratings). Compact design, suitable for sub-distribution panels and medium power circuits.
- ATO/ATC Series Fuse Blocks: Fuse holders for standard ATO/ATC automotive fuses. Available in 6 or 12 circuit versions, with common or independent terminals. Transparent protective covers, simplified installation.
- IP67 Series Waterproof Fuse Holders: IP67 waterproof fuse holders for exposed environments (engine compartments, outdoor bridges). Waterproof connections, screw-on cover with O-ring seal.
Electrical Accessories and Instrumentation
Blue Sea Systems also offers a full range of electrical monitoring accessories and instruments, enabling real-time monitoring of the onboard electrical system status and anticipating problems before they become critical.
- Digital Voltmeters and Ammeters: Precise monitoring instruments for voltage and current monitoring. High-brightness LED display, flush mounting, compatible with 12V, 24V, and 32V systems.
- Battery Monitoring Panels: Battery monitoring panels integrating voltmeter, ammeter and multi-bank monitoring. Function for calculating remaining battery life and deep discharge alert.
- Measurement Shunts: Precision shunts for DC current measurement, available from 50A to 500A. 0.5% accuracy, compatible with Blue Sea Systems instruments or third-party monitoring systems.
- Terminal Blocks and Connections: Connection blocks, electrical terminal blocks, wiring terminals for clean and professional installations. Marine-grade materials, fully insulated, DIN rail mounting.
💡 Skysat's advice
To ensure a safe and durable electrical installation, Skysat recommends always using circuit breakers rather than fuses for all accessible circuits. Always size circuit breakers according to the cable cross-section (never solely based on the equipment) to protect the wiring from overheating. For multi-bank installations, prioritize the use of Automatic Charging Relays (ACRs) coupled with individual circuit breakers for each bank, ensuring intelligent load management while maintaining complete isolation for maintenance. Finally, always integrate voltage and current monitoring to anticipate electrical problems before they compromise safety or comfort on board.
