Blue Sea Systems 5025 ST Blade Fuse Block 6 Way Circuits with Negative Bus and Cover, 100 Amps

Great 12v fuse block

Works for my application

I really like this fuse block. It looks and feels nice and solid. I installed it on my motorcycle (under the seat) so I easily can add accessories to it. Once connected the fuse block via a relay to a switched 12V wire, I only have to connect the pos. and neg. wires of the accessories to the fuse block. Very easy, and no messing with inline fuses. I also like that it has a pos. and neg. side, so I don't have to connect all the negative wires to my battery or grounded bolts. It just makes it very clear, also with replacing fuses. Another thing I like is the cover. I can put lugage on the fuse block without having to worry about damaging it I strongly recommend this product to motorcyclists who like to install accessories. It's way better than the cheap Chinese fuse blocks. Also way cheaper than the very expensive ones like the FZ1, which in my opinion you don't need, unless you want specific accessories turned on by ignition and other ones turned on always.

The Blue Sea Systems 5025 ST Blade Fuse Block is a top-notch solution for anyone looking to improve the organization and safety of their electrical systems, particularly in marine environments. With its durable construction and thoughtful design, this fuse block is perfect for powering multiple circuits without the hassle of tangled wires or confusing connections. One of the standout features of this fuse block is its capacity to hold up to 12 fuses, making it ideal for a variety of applications, from boats to RVs and automotive use. Each fuse slot is clearly labeled, allowing for quick identification and easy replacement, which is a huge time-saver when troubleshooting electrical issues. The block is designed with robust materials that can withstand harsh conditions, ensuring longevity and reliability even in the toughest environments. The transparent cover adds an extra layer of protection, keeping dust and moisture out while allowing you to easily check fuse status at a glance. Installation is straightforward, thanks to the included mounting hardware and clear instructions. The compact design helps save space, and the mounting options provide flexibility for different setups.

Update 7/7/2020: Ordered a replacement via amazon that arrived the next day. I had originally contacted the distributer on the recommendation of amazon and have yet to get a reply. So I just returned the original unit and purchased a new unit. Same outcome, just faster. The new unit is working great so far with my 24 volt battery bank. Hopefully it was just an isolated quality control failure. I have connected the main #10 post terminals on this fuse block to busbars on my battery box using 4AWG wire with #10 ring terminals. The 4AWG wire fits well and the cover clears the wire without needing any modification. The posts for the individual circuits are #8 so I have connected each of them using 10AWG wire and #8 ring terminals. There is plenty of room allowing the cover to clear everything nicely. The additional wires on the posts that can be seen in the original photo I posted of the failed unit are leads from a 24Volt battery charger/power supply that is fused separately. The photos contain the information I found on the Blue Sea website that shows the dimensions of the 6 circuit and 12 circuit fuse blocks. Original Review; This seems well made for what it is and made for a clean install. I am concerned about the quality of the electrical components since one of the six circuits was dead on arrival. The same wire and same fuse work in all of the other 5 circuits but do not work in the number 2 spot. I will send this one back and order another hoping my experience is an exception and not the normal, either way it is not very confidence inspiring for an electrical safety device to come new with a failure. I will update the review after receiving the replacement and returning the faulty unit.

I purchased this for my amateur radio setup and am very happy with it. It is relatively small, easy to get set up, and can accommodate many different devices. It is a lot cheaper than some of the specialized devices, but seems to be very good quality.

Picked this up as I was rigging out my Matecumbe 169. I dont need a lot of capacity, as the only connections that will run thru this are nav/anchor lights, GPS/DepthFinder, and a manual switch for my bilge pump. Two screws mounted it, I ran to the main power cutoff switch, with a fused link in the power cable, and ran the negative lead to the battery. I like that the ground was a part of the unit, removing the need to run a separate block for the black wires. Comes with little stickers for noting what is wired to each connection, but if your handwriting is as bad as mine, you may want your wife to print the info on them. LOL Seems like a fairly well constructed piece of equipment, so i really expect no issues with it. Overall, no complaints, other than the fact that Im too old and stiff to work inside the confines of an enclosed skiff locker.

I bought this to add another fuse panel to my Nitro boat. It was easy to install, the quality seems very good, and it has a very fair price as well. I've been running this on my boat for a year with absolutely no problems! Highly recommend!

I really rate Blue Sea products, and their fuse blocks are no exception. They’re solidly built, clearly labelled, and everything fits together exactly as it should — no fiddling or second-guessing. Compared to some of the unbranded or look-alike versions out there, these are in a different league. Yes, they’re a little pricier, but you’re paying for reliability and peace of mind — which is exactly what you want in an electrical setup. Definitely a worthwhile investment if you want something that just works and lasts.

Good build quality. Using it in my car.

Je suis satisfait de cette boite de fusible. A noter que le boitier permet d'y insérer deux fusibles de rechange, ce qui est pratique quand un fusible brule! J'apprécie ce petit détail PS: Contrairement à d'autres boites de fusible où n'il y a seulement que le positif (+), cette boite de fusible a aussi un négatif commun, ce qui habituellement facilite le filage et de façon sécuritaire.
