Fuse is also known as current fuse, and IEC127 standard defines it as "fuse-link". Its main function is overload protection. If the fuse is properly placed in the circuit, the fuse will break and cut off the current when the current is abnormally high and the heat is high enough to protect the safe operation of the circuit.
The fuse invented by Edison more than 100 years ago was used to protect the expensive incandescent lamps of that time. With the development of the times, the fuse protects the electrical equipment from overheating and avoids the serious damage caused by the internal faults of the electronic equipment.
