Blue Sea Systems ST Blade Fuse Block: Centralised Power Distribution for Marine and RV Systems

Streamline Your 12V and 24V Electrical Systems

The Blue Sea Systems ST Blade Fuse Block (12 Circuits) is the industry standard for consolidating branch circuits in demanding mobile environments. Designed to eliminate the "rats' nest" of in-line fuses and messy wiring often found in boats, caravans, and 4WD canopies, this distribution block offers a professional, safe, and reliable solution for managing your DC electrical connections.

Engineered for 12V and 24V systems (rated up to 32V DC), this unit allows you to power up to 12 separate accessories—such as fridges, lighting, water pumps, and navigation electronics—from a single reliable source. With a maximum total amperage of 100A per block and 30A per circuit, it is robust enough to handle the power requirements of modern off-grid setups while ensuring specific circuits are protected against overcurrent faults.

Integrated Negative Bus for Simplified Wiring

One of the standout features of this model is the integrated negative bus. In many electrical installations, finding a clean and accessible location for return lines (grounding) can be a challenge, often leading to stacked terminals on battery posts. This fuse block includes a built-in negative bus with #10-32 (Approx. M5) stud terminals, allowing you to run both positive and negative wires to the same block.

This design not only saves significant installation time but also reduces the number of connections required, minimising voltage drop and potential failure points. It creates a compact, self-contained power hub that makes troubleshooting easier in the future.

Marine-Grade Durability and ABYC Compliance

Built to withstand harsh saltwater and outdoor environments, the unit features tin-plated copper buses and fuse clips. This plating provides superior corrosion resistance compared to bare copper, ensuring consistent conductivity over the life of the vessel or vehicle. The base is constructed from reinforced polycarbonate, offering excellent heat resistance and strength.

The included insulating cover is designed to satisfy ABYC and USCG requirements for electrical insulation, protecting the fuses from accidental short circuits. The cover features an easy-to-open push-button latch, storage space for two spare fuses, and label recesses that accept Blue Sea Systems' Small Format Labels (sold separately), ensuring your system is clearly identified and compliant.

Key Features

  • 12 Independent Circuits: consolidate varying loads into one central hub
  • Integrated Negative Bus: simplifies wiring by providing a central ground point
  • High Current Rating: Supports 100A total continuous current and 30A per circuit
  • Corrosion Resistant: Tin-plated copper components for marine longevity
  • Safety Cover Included: Meets insulation requirements and stores spare fuses
  • Wide Voltage Range: Suitable for 12V and 24V DC systems (Max 32V DC)

Installation and Technical Context

This fuse block is designed for versatility. It accepts standard ATO® and ATC® fast-acting blade fuses, which are widely available and easy to replace. The main positive distribution bus utilises a #10-32 (Approx. M5) stud, while the branch circuits use #8-32 (Approx. M4) screws with captive star lock washers to ensure secure connections even under vibration.

*Note: While rated for 100A maximum, typical de-rating factors apply based on ambient temperature and wire sizing. Ensure your supply cable is fused appropriately at the battery source.

Whether you are refitting a yacht or building a custom 12V system for a camper trailer, the Blue Sea Systems 5026 fuse block delivers the reliability and organization required for professional-grade electrical installations.

Recovery for Physical & Spiritual Losses!
Format: Paperback, Format: Paperback
9/22/24:God's timing is perfect, as is the timing of the release of this book, as I'm walking through an extended loss period and am ready to move on to the next chapter of my life (nicknamed "Job"). I first learned about this book via an author interview on CBN's "700 Club;" which totally piqued my interest, so I ordered it. Honestly, it was difficult for me to get through the forward & intro; however, I feel like the spirit of "distraction" was fighting me, warring against me taking back what I've lost via God. I powered through (while receiving an amazing amount of info from author), and by the time I got through the first several pages of chapter 1, the author's writing style relaxed, information flow slowed (going from drinking out of a fire hydrant to sipping out of a hose), it's become an easier read, full of great detailed information, scriptures for validation, deeply meaningful prayers & contracts offered as instruments for your recovery- use as weapons & armor against the enemy (if you choose), as well as examples of real life applications & their baffling/astounding results (as a visual learner this helped me visualize how these methods can be applied & worked). Jane Hamon writes this book in a way that you can IMMEDIATELY apply what you've read to your life- no need to wait to the end & tie it up all together with a neat bow. I will be able to apply this to many areas of my life & lives of others. Jane also included several pages of "Notes," enabling you to dig deeper into the various subjects & info the author reviewed for this amazing book. I've already sent this to people I know are suffering & open to hearing this word & immediately apply these prayers, contracts, exercises, etc to their lives. Remember, this IS a WAR FOR YOUR SOUL! Don't let distractions/evil pull you away from working through this towards your victory! I pray you are successful in heavenly replevin recovery, standing in the light of God, with the Holy Spirit riding within your heart, and Christ as your lamp that lights your path. God bless you. THANK YOU JANE HAMON! 9/24/24: To correct MISINFORMATION IN OTHER REVIEWS: In first 2 chapters alone, these Bible versions are specifically quoted: TPT, NIV, NLT, NASB, KJV, ESV, MSG... possibly more, but I just skimmed to bring forward this CORRECT info.
