The Victron Energy Fuse Holder for MEGA-Fuse provides a compact and secure mounting point for compatible MEGA-format fuses in high-current DC electrical systems. Its single-fuse design is well suited to RV, marine, camper van, overland, off-grid, battery-storage, and professional mobile-power installations where dedicated circuit protection is required.
A properly installed fuse holder provides the MEGA fuse with a secure electrical connection while keeping the fuse accessible for inspection or replacement. The holder uses M8 terminal studs with approximately 50.8 mm center-to-center spacing. An integrated protective cover helps shield the fuse and conductive connections from accidental contact.
