ST-Blade Fuse Blocks
Consolidates branch circuits and in-line fuses
The ST Blade Fuse Block was designed with fastener terminals to comply with ABYC Recommended Practices, and are built with tin-plated copper components for improved conductivity and lower operating temperatures. An optional cover protects the conductive surfaces from accidental shorting, labels each circuit, and stores spare fuses.
The ST Blade Fuse Block is ideal for use as a sub-panel in the DC distribution system. This solves the problem of using large and expensive circuit breaker panels as circuit protection for electronics and other branch circuits. With most circuit breaker panels a circuit breaker and an inline fuse are used for to protect electronic devices. By instead utilizing Blue Sea Systems ST Blade Fuse Block as a sub-panel, fuses more appropriate for electronics can be used, removing the need for inline fuses while only utilizing one position on the panel. This reduces the size of the panel needed and lowers the overall system cost.
- Independent and/or Common Source fuse block
- Fastener terminals for securing wires accept terminal rings
- One-piece stainless flange nuts ensure safe and secure connections
- Clear insulating cover with label recess satisfies ABYC/USCG insulation requirements
- Accepts ATO and ATC fast acting blade fuses (sold separately)
- Some models ignition protected or ingress protected

There was a problem filtering reviews right now. Please try again later.
Although this is marketed as a marine-application fuseblock, and has something of a cover, I would not rely on its being at all watertight -- but that's just fine for my application and maybe yours. In fact I just deleted the cover entirely for my situation.
I am thoroughly enamored of this piece of equipment and am recommending it to others in my MG car club. I will own up to the reason I find myself here... Original wiring of the car had coil and fuel pump unfused. When installing a new fuel line I screwed up and that metal fuel line had residual tension in it that caused it to jump into contact with the hot terminal of the fuel pump. Thus I smoked the wire and had to replace it. But I resolved to put a damn' FUSE into each of the many circuits, and I breathe far more easily now. It's a neat and tidy solution, far more organized than the multiplicity of in-line fuses that was my initial approach.
UPDATE: Its been more than a year since my installation. I am pleased with the fuse block. No corrosion. It was worth the money regardless of the sticker issue. I used a little sharpie marker to mark the stickers and it is starting to fade out and bleed now. I Took a picture of it when it was new and keep a printed copy with my tools on board and on my phone. Because its doing so well for me I bumped it up a star.
It was well worth the money and I still say if the stickers that were shipped with it were the same as the ones pictured then I would give it 5 stars.
I absolutely love the products from Bluesea. I have few other Blusea product in my racecar
