Victron Energy MIDI Fuse (30A–200A, 32V & 58V DC)

Compact DC circuit protection for branch and mid-current circuits

Victron's MIDI fuses deliver reliable bolt-down overcurrent protection in a smaller footprint than the MEGA-Fuse — the right choice for branch circuits like solar charge controllers, DC-DC chargers, windlasses, and distribution feeds in marine, RV, and off-grid systems. Standard versions mount on M5 studs — the same size as the Victron MIDI fuse holder — while the 58V-M6 versions have larger holes for M6 studs. They're available from 30A to 200A in 32V and 58V DC ratings, as single pieces or 5-packs.

Key features

• Compact, space-saving bolt-down design — M5 mounting on standard versions, M6 on the 58V-M6 five-packs
• 30A–200A ratings for mid-current branch and feeder circuits
• 32V versions for 12V/24V systems; 58V versions for 48V systems
• Available as singles or money-saving 5-packs for spares

Choosing the right MIDI fuse

• Pick an amperage that matches or slightly exceeds the circuit's maximum continuous current — a common rule is 1.25 to 1.5 times the device's full-load current.
• Make sure the fuse's voltage rating is equal to or higher than your system voltage: 32V for 12V and 24V banks, 58V for 48V banks.
• Match the mounting size: standard MIDI fuses fit M5 studs (including the Victron MIDI fuse holder); pick a 58V-M6 version if your busbar or holder uses M6 studs.
• Confirm your wire is rated for at least the fuse amperage you select.

MIDI fuses seat in the Victron Fuse Holder for MIDI Fuse. For higher-current main circuits (battery-to-inverter feeds), step up to the Victron MEGA-Fuse.
