Knowledge of car fuses?
The commonly used fuses in automobiles include high current fuses and medium low voltage fuses, also
known as blade fuses or insert fuses. Blade fuses and insert fuses are particularly commonly used. Blade
fuses (including automatic fuse box mini fuses), plug-in fuses, screw in fuses, and tube type fuse box flat
fuses. Among them, we can come into contact with medium-sized ATO, ATC or small fast melting chip
fuses and MAXI blade fuses. Zinc sheet fuses can carry small currents and short pulse currents, such as
headlight circuits and rear windshield defrosting, air conditioning, wiper and other branch protections.
The international standard colors for automotive fuse blade fuses include 2A gray, 3A purple, 4A pink, 5A
orange, 7.5A coffee, 10A red, 15A blue, 20A yellow, 25A transparent colorless, 30A green, and 40A deep
orange. According to different colors, different amperage values can be clearly distinguished.
The conductor inside the car fuse is made of zinc alloy, which has a low melting point. The size of the melt
needs to be calibrated very accurately in order to generate enough heat to melt the conductor and
disconnect the circuit when the rated current is reached. Fuses have two important operating parameters,
one is the operating voltage, and the other is the rated current. Car owners should choose according to
the voltage and current in the circuit when purchasing or replacing fuses. If there are any technical issues
