imjl Micro Cartridge Fuses 25-Pack, Multi-Color 15–40A MCASE Slow-Blow Assortment

These are imjl TAITONG 25 micro cartridge slow-blow fuses (MCASE type) in five amp ratings — a compact kit to replace and protect automotive circuits from overloads and shorts.

This compact assortment supplies five of each commonly used slow-blow micro cartridge fuse: 15A, 20A, 25A, 30A and 40A. Designed to suit newer vehicles that use shorter, mini box-shaped cartridge fuses (about 0.59 inches tall), this set gives you on-hand replacements for cars, SUVs and trucks. Color-coded housings make it easy to identify ratings quickly, and the slow-blow characteristic helps tolerate brief current surges found in many automotive accessories.

What types of vehicles and circuits do these fuses fit?

The MCASE micro cartridge format is found in many modern passenger vehicles and light trucks; this set covers typical auxiliary and accessory circuits. Use them for systems where slow-blow protection is specified or where a slightly delayed trip avoids nuisance opens from brief motor or inrush currents.

• Fits many Ford, Mondeo, Fox and modern vehicle fuse boxes that accept MCASE micro cartridges.
• Suitable for accessory circuits: lighting, audio, heated seats, wipers, power windows and similar loads.
• Sized for compact fuse compartments—0.59 inches tall micro box form factor.
• Slow-blow design tolerates short inrushes from motors and relays.

How do I choose the right amp rating from the kit?

Select the fuse with the same amp value as the original installed in the circuit. If the original is missing or unreadable, consult the vehicle’s manual or wiring diagram rather than guessing — using a fuse with a higher rating risks damage, while a lower rating will blow prematurely.

• Match vehicle panel markings or owner’s manual specified amperage exactly.
• Use the kit’s color-coded housings to quickly pick 15A, 20A, 25A, 30A or 40A fuses.
• If uncertain, verify circuit current draw or consult a professional before upsizing a fuse.
• Keep spares of the most-used ratings to reduce roadside downtime.

How are these fuses packaged and what does the kit include?
