57 micro fuses covering 5–30 AMP ratings in both Micro2 and Micro3 formats, pre-sorted in a 12-hole labeled plastic drawer with a converter included. Micro fuses are the standard fuse format in late-model import and domestic vehicles with compact fuse boxes — having the right amperage and blade type on hand means blown fuse diagnostics end at the fuse block, not at the parts counter.

What's Included

Micro2 fuses — 5A, 7.5A, 10A, 15A, 20A, 25A, 30A (compact two-blade format)
Micro3 fuses — select amperage ratings (three-blade format for higher density fuse blocks)
Fuse converter included — adapts micro fuse sizes for use in standard blade fuse sockets
12-hole labeled plastic drawer — pre-sorted by amperage and type
QR-coded layout included

Best For

Automotive service shops with late-model import and domestic vehicles — Micro2 and Micro3 fuses are standard in Toyota, Honda, Nissan, and many late-model domestic vehicles; a stocked assortment handles the full amperage range without individual sourcing
Fleet maintenance operations — mixed fleets with late-model vehicles often require Micro2 fuses for accessories, lighting, and control modules; keeping the amperage range stocked avoids vehicle downtime
Mobile service technicians — a compact 12-hole bin of micro fuses in a range of amperages belongs in every mobile service kit for fast blown fuse diagnosis and replacement on-site

Micro2 vs. Micro3 vs. Mini vs. Standard Blade Fuses

Modern vehicles use multiple fuse blade formats depending on the fuse block design. Here's how they compare:

Micro2 (Low-Profile Mini) — the most compact common blade fuse format; used in late-model import and domestic vehicles with space-saving fuse blocks. Two blades, smaller footprint than Mini or ATO.
Micro3 — three-blade format used in very high-density fuse boxes where even more circuits need to fit in a smaller space. Less common than Micro2 but found in late-model European and some Asian imports.
Mini (ATM) — slightly larger than Micro2, two blades; one step up in size and very common in domestic vehicles from the 1990s onward.
Standard (ATO/ATC) — the traditional two-blade blade fuse, still used in older and heavy-duty applications.

Always replace a blown fuse with the same amperage and same blade type. The converter included in this kit allows a Micro2 fuse to be used temporarily in a standard blade socket — useful for field diagnosis, not a permanent installation. Questions? Contact us.
