  According to the protection form, it can be divided into overcurrent protection and overheating protection. The fuse used for overcurrent protection is commonly referred to as a fuse (also known as a current limiting fuse). The fuse used for overheat protection is generally called "Thermal cutoff". Thermal cutoff can also be divided into low melting point alloy, temperature sensing trigger and memory alloy (Thermal cutoff is used to protect heating appliances or easily heating appliances from high temperature, such as hair dryer, electric iron, rice cooker, electric stove, transformer, motor, etc.; it responds to the rise in temperature of electrical appliances and does not care about the working current of the circuit. Its working principle is different from "current limiting fuse").

  According to the scope of use, it can be divided into: power fuse, machine tool fuse, electrical instrument fuse (electronic fuse), and automotive fuse.

  According to body integration, it can be divided into: large, medium, small, and micro. According to the rated voltage, it can be divided into: high-voltage fuse, low-voltage fuse, and safety voltage fuse.

  According to the breaking capacity, it can be divided into high and low breaking capacity fuses.

  According to shape, it can be divided into: flat head tubular fuse (also divided into internal and external welding fuses), pointed tubular fuse, blade fuse, spiral fuse, plug-in fuse, flat fuse, wrapped fuse, and patch fuse.

  According to the melting speed, it can be divided into: extra slow fuse (usually represented by TT), slow fuse (usually represented by T), medium speed fuse (usually represented by M), fast fuse (usually represented by F), and extra fast fuse (usually represented by FF).

  According to standards, it can be divided into: European standard fuses, American standard fuses, and Japanese standard fuses.

  According to the type, it can be divided into: current fuse (patch fuse, mini fuse, plug-in fuse, tubular fuse), Thermal cutoff (RH [block type], RP [resistance type], RY [metal shell]), self recovery fuse (plug-in, lamination, patch).

  According to size, it can be divided into: SMD type 06030805120612181220162920; Non SMD type Φ two point four × 7, Φ three × 7, Φ three point six × 10, Φ four point five × 15, Φ five × 20, Φ five point one six × 20, Φ six × 25, Φ six × 30, Φ six × 32, Φ eight point five × 8, Φ eight point five × eight × 4, Φ ten × 38, Φ fourteen × 51.
