The Victron Energy MEGA-Fuse 400A / 32V DC (Pack of 5) delivers high-amperage circuit protection for large 12V inverters, battery banks, and DC distribution systems. Best for off-grid, marine, and RV owners protecting big inverter circuits, the 5-pack is priced at $10.00, down from $15.30 — buy online and save 35%.
A 400A fuse at 12V DC suits large inverters in the roughly 3000–4000W continuous range, accounting for peak surge. Always size the fuse to your cable ampacity and inverter max draw: fuse amps ≥ 1.25 × continuous max current, and never exceed your wire's rating.
On a 24V inverter, current halves, so a 400A fuse supports proportionally larger loads (up to ~8000W class); many 24V installations instead use 200–300A fuses. Check your inverter's manual for the recommended fuse size.
Standard MEGA-fuse format (approximately 10.3 × 38.9 mm stud spacing per MEGA-fuse convention), fitting the Victron MEGA-Fuse Holder and other standard MEGA fuse holders. Rated 400 amps at 32V DC max system voltage.
At $10.00 versus $15.30 for a genuine Victron 5-pack, you save 35%. Add coupon OUTPOST12 for an extra 12% off. Note: this item alone falls below the $45 free-shipping threshold — bundle with a fuse holder or cables to ship free.
Genuine Victron MEGA-fuses guarantee correct ratings and reliable blow characteristics; bargain no-name fuses can fail to protect or blow prematurely. For safety-critical battery circuits, genuine is worth it — especially at $2 per fuse.

At 12V DC, a 400A fuse typically protects inverters in the 3000–4000W continuous range including surge headroom — always match the fuse to your cable ampacity and inverter manual.
At 24V, current is halved, so many 24V installs use 200–300A fuses; a 400A fuse suits very large 24V loads. Follow your inverter's fuse recommendation.
Yes — the standard MEGA-fuse format fits the Victron Energy MEGA-Fuse Holder and other standard MEGA fuse holders.

Genuine MEGA-fuses guarantee accurate amp ratings and reliable blow characteristics, which generic fuses may not — critical for protecting expensive batteries and inverters.
Genuine Victron MEGA-fuses at a fraction of what local marine shops charge. They fit my fuse holder perfectly and I keep spares in the electrical bay. Protection you don't think about until you need it — buy the pack, not a single.
Genuine part, fast shipping, good price. Can't ask for more.
The fuses themselves are exactly what they should be — proper MEGA-fuses with clear amperage marking. Just arrived in a simple bag rather than retail packaging. Function is what matters and these deliver.
Running a 3000W inverter on my battery bank means a 400A fuse is the first line of defense. I verified continuity and the specs match the genuine article. Five-pack means I'm covered for years. Peace of mind for ten bucks.
Installed in the holder, correct rating, no issues after three months of use. Would buy again when I need spares.
I don't cheap out on overcurrent protection, and Victron fuses are the ones my system was designed around. Have blown one legitimately during a short and it did its job perfectly — the rest of the system was unharmed. Replaced with another from this pack.
