MRBF or Marine Rated Battery Fuses mount directly onto the battery terminal, making your wiring cleaner and installation faster. Unlike traditional inline fuses that require extra cables and crimps, MRBF fuses keep things simple—one wire, one fuse, directly on the terminal. In this video, I’ll show you why they’re a great choice, when they’re not the best option, and how to size them properly so you don’t risk overheating your wires or wasting money. Traditional inline fuses require more wiring, more connection points, and add unnecessary resistance. With an MRBF fuse, you eliminate all that. Plus, they allow more connections—up to five lugs on a single fuse holder, or even eight with a double MRBF holder. This makes it easy to fuse your inverter and charge controller separately without needing extra busbars or junctions. But MRBF fuses do have their limits. If your battery bank is too large, they may not be able to safely interrupt a short circuit. Generally, they’re suitable for up to 1000Ah in 12V systems, 500Ah in 24V, and 200Ah in 48V. If your setup exceeds this, you’ll need a Class-T or NH00 fuse instead. Cost is another factor. MRBF fuses are great for one or two batteries, but if you have three or more batteries in parallel, a fuse busbar with Mega fuses is a much cheaper option. I’ll break down the price differences so you can make the best choice for your system. Finally, I’ll show you how to correctly size your fuse and wire. Using the simple formula Watts ÷ Volts = Amps, I’ll walk you through choosing the right fuse size, applying a safety factor, and selecting the correct cable gauge so your fuse blows before your wire overheats.
