DESCRIPTION
Blue Sea Systems ST Blade Fuse Block: Professional Circuit Protection for Marine and Automotive Systems
Centralised Power Distribution for 12V and 24V Setups
The Blue Sea Systems ST Blade Fuse Block offers a robust solution for consolidating branch circuits in boats, caravans, 4WDs, and camper trailers. By replacing messy nests of inline fuses with a single, compact distribution hub, you significantly improve the safety, reliability, and serviceability of your DC electrical system. Designed to withstand the rigours of marine environments, this unit is equally at home in high-vibration automotive applications.
This 6-circuit model features a positive distribution bus with a #10-32 (Approx. M5) stud, allowing you to feed power to six separate accessories from a single source. It is rated for a maximum operating voltage of 32V DC, making it perfectly suitable for both 12V and 24V systems commonly found in recreational vehicles and marine vessels.
Integrated Negative Bus for Simplified Wiring
One of the standout features of this model is the integrated negative bus. In many electrical installations, gathering the negative return wires can be a challenge, often resulting in messy terminal stacks on the battery. This fuse block includes a dedicated negative bus block with #8-32 (Approx. M4) screws, providing a clean, common return path for each circuit directly at the fuse block. This simplifies troubleshooting and ensures a professional, organised finish to your wiring project.
Marine-Grade Durability and ABYC Compliance
Engineered for longevity, the fuse block utilises tin-plated copper buses and fuse clips. This material choice offers superior conductivity while resisting corrosion, a critical factor for equipment exposed to salt mist or humidity. The included insulating cover satisfies ABYC and USCG requirements for insulation, preventing accidental short circuits and enhancing onboard safety.
The cover features an easy-to-open push-button latch, providing quick access to fuses when you need it most. It also includes storage space for two spare fuses, ensuring you are never left without a replacement in an emergency. The label recesses are designed to accept Blue Sea Systems Small Format Labels, allowing for clear identification of each circuit (e.g., "Lights," "Pump," "Fridge").
Technical Specifications and Capacity
This unit is designed to handle significant power loads, supporting a maximum of 100A per block and up to 30A per individual circuit. It accepts widely available ATO® and ATC® fast-acting blade fuses, making replacements easy to source anywhere in Australia.
*Note: Maximum current ratings are listed; typical de-rating factors apply based on ambient temperature and installation conditions.
Key Features
- 6-Circuit Consolidation: Clean up your wiring by grouping accessories into one protected hub.
- Integrated Negative Bus: simplifying wiring by providing a central location for negative return lines.
- High Current Capacity: Supports up to 100A total current and 30A per circuit.
- Corrosion Resistant: Tin-plated copper components ensure long-term reliability in harsh environments.
- Safety Cover Included: Meets ABYC/USCG insulation standards and includes spare fuse storage.
- Versatile Voltage: Rated for 32V DC max, making it ideal for 12V and 24V electrical systems.
- Universal Fasteners: Accepts ring or snap fork type terminals for secure connections.
Easy Installation
Mounting is straightforward using #8 (M4) screws. The main positive and negative input studs are #10-32 (Approx. M5), providing a solid connection point for heavy-duty feed cables. The screw terminals for branch circuits are #8-32 (Approx. M4) with captive star lock washers to ensure connections remain tight even under vibration.
