Victron 5-Pack of 400A 80V Ceramic MEGA Fuses

The 400 A Victron MEGA fuse is the top of this range and is usually used on the main battery feed for a large inverter or inverter/charger. At 12 V, 400 A is about 4,800 W of capacity, at 24 V it is 9,600 W, and at 48 V it is 19,200 W. A 3,000 W inverter running on 12 V can pull well over 250 A from the battery, which is where a 400 A fuse fits.

These fuses are rated to 80 V DC, so they work on 12, 24 and 48 V banks. They bolt into Victron's Lynx Distributor and the five-position MEGA fuse holder bus bar, and the bolted terminals are what you want at currents this high. The pack of five covers the main fuse and leaves you with four spares.

A 400 A circuit needs very heavy cable, so confirm the cable is rated for that current over its full run before using this size. Clean the contact faces and torque the holder nuts to spec to prevent hot spots. The Lynx modules and bus bars these fuses mount in are in our bus bars and power distribution section.
