imjl Micro MCASE cartridge fuses 25‑pc multi‑color (15–40A) — slow‑blow, compact 0.59in for cars & trucks

These are a 25-piece assortment of TAITONG micro slow-blow MCASE (FMM) cartridge fuses in five color-coded amp ratings (15, 20, 25, 30, 40 A) designed to protect modern vehicle circuits and replace blown mini box-style fuses.

As newer cars and light trucks adopt more compact high-current fuse designs, having a ready set of micro cartridge fuses saves time and prevents roadside frustrations. This TAITONG kit includes five fuses at each amp rating, using industry-standard colors for quick identification and a compact 0.59-inch height to fit micro MCASE fuse holders commonly found in recent Ford, Mondeo and many other models. The slow-blow (time-delay) characteristic helps tolerate harmless inrush currents while still protecting wiring and electronics from sustained overloads or short circuits.

How will this fuse kit fit my vehicle's fuse box?

These fuses follow the MCASE/FMM mini box cartridge dimensions used by many current vehicles. Because they are 0.59 inches tall and designed for female micro slow-blow holders, they slide into compatible sockets where older larger fuses won’t fit. Always compare shape and measurements with your vehicle’s existing fuse before replacing.

• Includes five each: 15 A (color), 20 A (color), 25 A, 30 A and 40 A for common circuits.
• 0.59-inch height to match modern micro MCASE fuse compartments.
• Female micro slow-blow type for time-delay protection in inrush-prone circuits.
• Color-coded for fast visual amp identification during roadside swaps.

What kinds of circuits should use slow-blow MCASE fuses?

Slow-blow (time-delay) fuses are appropriate where brief startup or surge currents occur but sustained faults must still be interrupted. Typical applications include electric fans, motors, accessory amplifiers, power windows, and certain lighting circuits. Use the correct amp rating for the circuit to avoid nuisance blows or inadequate protection.

• Good for motor-driven accessories and systems with initial current surges.
• Not ideal for circuits requiring very fast interruption of short spikes.
• Select the amp rating matching the vehicle’s original fuse chart or service manual.
• Avoid substituting higher amperage than specified; that risks wiring damage.

How does this kit help with roadside or workshop repairs?

Carrying an assortment avoids last-minute trips to autoparts stores and lets you quickly restore a blown fuse so the vehicle can be safely moved or driven to a service location. The set’s compact, organized pack keeps five common amp ratings on hand and eliminates guesswork through color coding. It’s a practical addition to a glovebox, toolbox or emergency kit.

• 25-piece pack supplies multiple replacements for frequent circuits.
• Color-coded for fast selection when under time pressure.
• Compact packaging fits in vehicle storage compartments or tool kits.
• Designed for aftermarket use with many modern vehicle models.

Are these fuses compliant with vehicle electrical needs?

The TAITONG micro cartridge fuses are specified to meet the demand for smaller high-current protection found on new model vehicles.
