100A MIDI Fuse – 2 Pack for Marine DC Circuit Protection
Keep your high-current DC circuits protected with these 100-amp MIDI fuses. Sold as a 2-pack, they're a practical way to stock a spare while keeping your primary circuit protected. MIDI fuses are a compact, reliable alternative to ANL fuses for mid-range current applications, and are commonly used in marine electrical systems where space is at a premium.

Parts Desk Insights
MIDI fuses are a great middle ground between blade fuses and full ANL fuses — compact enough for tight installs but rated for serious current. The 100A rating suits most mid-draw accessories and branch circuits. If your system runs lower loads, the 80A MIDI Fuse 2-Pack (BSS-5255) is the next step down. For main battery cable protection at higher amperage, pair with the 300A ANL Fuse Block with Cover – BSS-5005 on your primary feed. Always match fuse amperage to your wire gauge, not just the load rating.
