Great option for a clean battery terminal fuse system. I have used this item on a few projects and love how clean it turns out. I'm a custom builder and love the blue sea products.

This worked great on my 48v battery bank of 8 12v 280 AH ecoworthy batteries. Save so much wire and headaches with the bussbars. Note: do not get the cheaper bojack fuses as they have not been reliable in my experience. I did not like spending $18 for the better fuse but had to anyway…

Sehr gutes Produkt, ermöglicht eine schlanke Elektroinstallation mit dem Nachteil, daß die Sicherungen ihren Preis haben. Für mich aber trotzdem angenehmer, als eine extra MEGAfuse-Box plus Kabel einzubauen.

Product itself is good.The used very good one I purchased was not worth the discounted price.Busbar had been filed away, fuse mounting studs cut and filed down, some slight bending of the terminal mount side. It won’t properly hold a fuse as the posts are too short for the nut to securely fasten it. Poor condition would have been a better description.The other one I purchased is great!

Works great only challenge is to keep it square while tightening nuts

Seems very well built. This is a good solution if you're looking for terminal fuses.

Eine super Idee, leider nicht entsprechend den Sicherungsspezifikationen für CF 8.Die bekommen nur mit Distanzscheiben Kontakt.Meine Empfehlung: Distanzscheiben 12x18x0,3 mitliefern

The picture and info are misleading. The fuses are not included.

This fuse system--marine rated battery fuse (MRBF)--was originally designed for boats and marine environments, but it's tremendously useful in any context that involves a high-current battery bank, such as automotive or solar power systems. The product makes so much sense that I don't understand why it's not the standard. Most high-current battery fuses require a cable from the battery terminal to the fuse block, and then from the fuse block to the rest of the circuit. Very unwieldy. Plus the cable that leads from the battery to the fuse block is itself unfused and can lead to a short!This fuse block attaches directly to the battery terminal itself--eliminating the unfused cable and providing support for the fuse block so that it's not just floating in air. It can protect two different circuits, each with its own amperage requirements. And it does so in a nice tight little package that just puts all other fuse blocks to shame. The 5/16" studs are nice and long so they can accommodate the terminal lugs from fat high-amp cables. The block itself can be fitted with standard 5/16" or 3/8" bolts.MRBF fuses are more difficult to get than other types, but they're reasonably priced and on par with competing high-current fuse systems such as ANL and Class T. Note however that MRBF only goes up to 300A--perhaps the only real downside.Blue Sea should take the next logical step and offer three and even four-circuit terminal fuse blocks. To avoid the extra height (or length), they could just make right angle turns. In any case, let's hope this innovative system remains available well into the future.

It has always been a problem to get that first fuse connected close to the battery. This little device makes that a piece of cake. It is a solid device with the heft to take the load of having heavy cables attached. The studs are a little long, but that means they are long enough to bolt on a couple of cables with room to spare. I also like that you can get single and double fuse versions.I'm retrofitting my utility trailer and my truck camper with these fuse holders. Getting rid of the fuse holder, and thus the terminal lugs, on the wall next to battery cleans things up and simplifies the wiring because it's now a straight shot to the disconnect switch.The only down side is that most auto stores don't stock the fuses, so keep a spare or two on hand.
