What are the types of automotive fuses?

Types of automotive fuses: 1. Blade-type fuses can be divided into: micro blade fuses, mini automotive fuses, standard automotive fuses, and maxi automotive fuses. The rated current ranges from 1-40 amperes (A) to maxi 30-120 amperes (A), with a rated voltage of 32 volts (V). 2. Bolt-down fuses can be divided into: mini bolt-down fuses and maxi bolt-down fuses. The rated current ranges from 30-150 amperes (A) to maxi 40-800 amperes (A), with a rated voltage of 32/125 volts. 3. Automotive glass tube fuses can be divided into: 6.35*30mm glass tube fuses, 6.35x31.75mm glass tube fuses, and 10*38mm glass tube fuses. The rated current ranges from 0.5-20 amperes (A) to 10x38mm 20-80 amperes (A), with a rated voltage of 32 volts (V).
There are quite a few types of automotive fuses. From my experience in daily car repairs, they mainly include blade fuses, mini fuses, and glass tube fuses. Blade fuses are the most common—they look like colored plastic pieces, with different sizes corresponding to different amperage ratings, and are used in circuits like headlights and audio systems. Mini fuses are more compact and suitable for modern vehicles' complex systems, such as electronic control units. Glass tube fuses are older—they're transparent tubes with a wire inside, making it easy to see if they're blown, though they're less commonly used now. These fuses are mainly located in the fuse box. Don’t underestimate them—choosing the wrong amperage rating can lead to circuit damage or vehicle short circuits. I recommend checking the color codes when replacing them and cross-referencing the owner’s manual to avoid counterfeit products. For safety, regularly inspect the fuse box and promptly replace blown fuses to prevent major issues.
