MRBF Fuse Holder can be mounted directly onto battery terminals.
Compact in size, perfect for tight space installations.
Interchangeable and replaceable fuses, sizes ranging from 30A to 300A.
MRBF Fuse Holder can be mounted on busbars.
Marine Rated battery Fuses
Designed for the most demanding environment to provide high current protection for the tightest space constraints. Suitable for main and auxiliary circuit protection such as alternator outputs, starter motor inputs and accessory circuits. Alleviates having to make up a short wire to connect to a standard fuse block to the battery. Safe for installation aboard gasoline powered boats.
- DO NOT mount fuse directly onto battery post. Fuses should be mounted on the MRBF terminal fuse block. (See examples below)
- Ingress Protection: IP66, protected against powerful water jets
- Ignition Protected: Per SAEJ1117
Application
Full range circuit protection for automotive and marine applications. The breaking capacity meets the requirements of conventional vehicle batteries and 12V, 24V and 42V electrical networks. Compact, high-amp fuse appropriate for DC Main, inverters, windlass, and bow thruster circuit protection. Provides high current protection in tight space constraints. Ignition protected when used with MRBF Terminal Fuse Blocks. Isolated stud design uses standard M8 hardware and permits stacking of terminals.

Used in car battery with inverter circuitry. Seems to do the job as everything is working perfectly.

I bought a bunch of these to install on the batteries on my boat. I have a vry large house battery, using golf cart flooded batteries (Yeah, I know that LI are supposed to be better, but I would have to re-wire and re-configure a LOT of stuff). They are easy to use if you have enough room on the battery studs, or can make a stud extender. I flattened a piece of 1/2 inch copper pipe and drilled holes in it to add several of these fuses that protect the wiring coming off of the batteries.I had one pop last year, when the anchor windlass jammed, and I did not have a spare fuse on board. But very easy to bypass them in an emergency, if absolutely necessary.Recommended.

My fault I blew a fuse, but I knew where to find a replacement. These aren't real common that I know of, but I've ordered from Bay Marine before.

These work great for fusing higher amperage loads that are directly connected to batteries, terminal bars, or high amperage switches on DC battery powered systems such as RVs, boats, or off-grid buildings. Note that you need to buy a matching fuse holder. You can get these at lower (total) cost from other sources if you shop around, so 4 stars.
