Waterproof Cap Protection
Our battery terminal fuse comes with a Waterproof Cap, which prevents accidental short circuit, it is waterproof and dustproof, and reduces the influence of environment on the performance of the fuse holder.

It fits perfectly with standard battery terminals.Waterproof Cap: The included waterproof cap adds an extra layer of protection, making it suitable for use in various environments, including marine applications.Versatile Use: This fuse block is suitable for a wide range of applications, including new energy vehicles, RVs, boats, and construction vehicles.Cons:Size Considerations: The fuse block is relatively large, so it may not be suitable for applications with limited space.Price: While the quality justifies the price, it is on the higher end compared to some other options on the market.Overall: The Joinfworld MRBF Terminal Fuse Block 300A is a reliable and durable choice for anyone needing a high-current fuse block.

Works well ( I haven’t tripped it so I can’t guarantee quality of fuse itself).Just make sure to place washers between fuse and wire otherwise you moght melt the plastic casing.

Using one of these to protect a new bus bar that I installed in my truck. The build quality is nice and strong and it has so far functioned exactly as intended. I prefer this form factor of fuse holder versus other options out there because it simplifies the install without a need to mount other types of fuse holders. I did apply dielectric grease during install to help protect the metal components from corrosion. Time will tell how durable it is, but I am very pleased with it so far.

Even though I can't see that anything inside the fuse itself is melted, it is apparently dead, as no power will flow from the terminal when the cables are installed via the fuse holder, but everything works just fine as soon as I bypass it. UPS 80 miles away, so not worth returning this. What a waste.

Battery bank protection. One on each battery before connecting to a buzz bar. Great protection in case of thermal run-away or excessive load on individual batteries.

I used this for when I did a big 3 wiring upgrade on my 1964 impala SS. I ran a 1/0 copper spartan welding wire (great wire, available on amazon) from my 200 amp 1 wire alternator. I wanted to keep the top post open for all my other wiring (air bag suspension system compressors vlair 485's , big stereo 3000+ watts of amps, and a battery isolator running to another optima yellow top in the trunk for dual charging, SAE 3.3ft 10gauge fused connector hidden in bumped to plug a trickle charger in without opening the hood, etc.) So this runs dedicated to the side post of an optima red top 75/25 battery. I put a 200amp fuse on it and keep an extra in my car tool bag, although I haven't had any issues.
