According to the form of protection, it can be divided into: over current protection and over temperature protection. A fuse for overcurrent protection is a commonly used fuse (also called a current limiting fuse). Fuses for overheat protection are commonly referred to as "temperature fuses." The temperature fuse is further divided into a low-melting alloy shape and a temperature-sensing trigger shape and a memory alloy shape, etc. (the temperature fuse is protected against the heat of the heating appliance or the heat-generating appliance, for example: hair dryer, electric iron, rice cooker Pot, electric furnace, transformer, electric motor, etc.; it responds to the rise of the temperature rise of the electrical appliance, 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 fuses, machine tool fuses, electrical instrument fuses (electronic fuses), car fuses.
According to the volume, it can be divided into: large, medium, small and miniature.
According to the rated voltage, it can be divided into: high voltage fuse, low voltage fuse and safe voltage fuse.
According to the breaking capacity, it can be divided into: high and low breaking capacity fuses.
