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.

Works Good!
Color: Grey
I was concerned it was going to be too small, especially since the tall portion design doesn't allow you to hang on the ourside....But I have a very nice glass container of dish detergent in it, a bottle of hand soap, and the tall container for taller brushes, straw cleaners, etc. It fits everything pretty well. Wouldn't be able to add a sponge to it, but I have a holder with suction cups on the inside of my sink for the sponge and keeps it out of sight, so it works for me. But if you have a stuff at your sink, it probably wouldn't. Though if you like the design (which is very nice), you could always use two, one on each side of the faucet. I also returned one because even though the extra container could hang on the outside, it was short enough and everything kept falling out of it. This taller one works much better...but again, it too is somewhat limited on size and storage. I much prefer everything organized and in its place, and this provides that.

Great little sink organizer!
Color: Black
This is a lovely addition to my kitchen sink to handle all of my dishwashing tools. And I really like the DE base to catch all the drips and water drainage. The separator in the middle is moveable so you can determine how big or small you want the partitions. It was packaged very nicely and came with stick on feet to protect your countertops or sink edge. Highly recommend if you were looking for something this functional.

Nice Product
Color: 2 Tier-Black, Color: 2 Tier-Black
Super Handy and So Stylish — A Must-Have for Any Kitchen! I’m really impressed with the Sinnsally Kitchen Sponge Holder! It’s simple, practical, and makes keeping my sink area neat so much easier. The 2-tier design is brilliant — the top shelf holds my sponges perfectly, while the bottom area keeps scrubbers and brushes organized and easily accessible. The stainless steel looks sleek and modern, and it has held up beautifully with daily use. Water drains well so everything dries quickly, and cleanup is a breeze. No more soggy sponges sitting around! Installation was quick and easy — it fits nicely right by the sink without taking up too much space. This little holder has made a big difference in keeping my kitchen tidy. Highly recommend for anyone who wants a clean, organized sink area with a touch of style!
