    The Blue Sea Marine Rated Battery Fuses are ideal for mounting directly to battery banks to busbars, or wherever you need a 30A to 300A fuse to protect a circuit (see images to your left).

    IMPORTANT: When using an MRBF on a battery bank that can be used to start a sailboat AUX engine, a 250A to 300A fuse is recommended as a bare minimum. Be sure your wires ampacity rating can handle this. For general sizing guidance click on the ABYC ampacity table in the images to your left.
