What are the types of fuses

View: 4907/26/2021  

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 the fuse (also known as current limiting fuse).


The fuse used for overheating protection is generally referred to as "temperature fuse".


Temperature fuse can be divided into low melting point alloy shape, temperature sensing trigger shape, memory alloy shape, etc. (temperature fuse is used to protect heating appliances or easily heating appliances from excessive temperature, such as hair dryer, electric iron, electric rice cooker, electric furnace, transformer, motor, etc; It responds to the increase of temperature rise of electric appliances and ignores 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 automobile fuse.


According to the 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 breaking capacity fuse and low breaking capacity fuse.


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 tubular fuse, guillotine fuse, spiral fuse, plug-in fuse, flat fuse, wrapped fuse and patch 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, American fuse and Japanese fuse
