The Victron Fuse Holder for MEGA Fuse is the standard single-fuse mount for protecting your main battery cable — a robust molded enclosure with M8 bolts on each side that accepts any MEGA fuse from 60A to 500A. Used for main bank fusing or single high-current circuit protection on inverters, MPPTs, and DC distribution.
Why fuse your main battery cable
An unfused main battery cable is one of the most dangerous failure modes in a DC system. If the positive cable chafes through to ground (against a frame, hose, or sharp edge), it can deliver thousands of amps until either the wire burns through or the battery explodes. A properly sized MEGA fuse interrupts the fault current safely, preventing fire and explosion.
ABYC (marine) and NEC (residential) codes require main bank fusing within 7 inches of the battery positive terminal.
