Type of fuse

The following are fuse types with different classification methods:
According to the protection form, it can be divided into overcurrent protection and overheating protection. The fuse used for overcurrent protection is commonly known as fuse (also known as current limiting fuse). The fuse used for overheating protection is generally called “temperature fuse”. The temperature fuse is divided into low melting point alloy shape, temperature sensitive trigger shape and memory alloy shape. The temperature fuse is used to prevent the temperature of heating appliances or heat prone appliances from being too high, such as hair dryers, electric irons, electric cookers, electric stoves, transformers, motors, etc; It responds to the rise of the temperature of the electric appliance 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 fuse, electrical instrument fuse (electronic fuse), automobile fuse.
According to volume integral, 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 breaking capacity, it can be divided into high and low breaking capacity fuses.
According to the shape, it can be divided into: flat head tubular fuse (which can also be divided into internal welding fuse and external welding fuse), pointed head tubular fuse, guillotine fuse, spiral fuse, insert type fuse, flat type fuse, wrap type fuse and patch type fuse.
According to the fusing speed, it can be divided into: extra slow fuse (generally represented by TT), slow fuse (generally represented by T), medium speed fuse (generally represented by M), fast fuse (generally represented by F), and extra fast fuse (generally represented by FF).
According to the standard, it can be divided into: European fuse (VDE), American fuse (UL) and Japanese fuse (PSE).
