Great product. These are a good value, easy to install, and a convenient size for the post of nearly all LFP batteries. They're also built like a tank, and therefore suitable for a wide range of use cases. I fuse all of my LFP batteries I find it useful to have two fuses on the block for larger batteries (200 and 300 Ah) because they often run circuits with higher and lower current drain, so I want separate fault protection for the distribution blocks on those circuits. Note: I use only Buss fuses because I don't trust low-cost knock-offs to blow at their rated current based on testing and research I have seen.

I have done several DIY solar projects. For safety, I always put a proper sized fuse at the battery. With this MRBF Terminal Fuse Block, I can simply mount the fuse right to the battery post. It is simple to mount, small and very high quality. I only needed a single fuse block, but they had a super special where the dual fuse block was way less expensive then a single fuse block. So I bought the double. This is a very well designed piece if equipment. The build quality is superb and it is made for harsh salt water environments.

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.

Overall good product, the picture shows fuse are there but actually not.

Using these for an upgrade of my batteries for the travel trailer. They (and the associated Buss fuses you need to buy separately) are on the pricey side, but look robust. They're name brands (I have other Blue Sea components that came OEM with the trailer), so I'm confident they will stand the test of time and perform as needed.

This compact, well-made design worked perfectly in my fifth-wheel RV. I made the switch from lead acid to LiFePO4 battery power with solar charging. I needed a compact device to provide a primary fused circuit breaker right at my 300 Sh battery. This does the job of providing protection at a reasonable cost.

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!

Produit de qualité

Ridiculously expensive. Well made product but you have to question the cost. Quality costs... unless you're being ripped off!

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.

Arrivato in una bustina trasparente anonima. Non posso escludere che si tratti di merce non originale Blue Sea System

great
