The role of the fuse

A fuse is also called a current fuse, which is mainly composed of a melt part, an electrode part, and a bracket part. The function of the fuse is mainly to protect the electrical equipment from overcurrent and overheating, and to avoid serious injuries caused by internal failures of electronic equipment.

Fuse
A fuse is also called a current fuse, and the IEC127 standard defines it as a "fuse link". It generally consists of three parts, one is the melt part, which is the core of the fuse; the second is the electrode part, usually two, which is an important part of the connection between the melt and the circuit; the third is the bracket part, which is the support An important part of the whole fuse.


Role
The function of the fuse is mainly to protect against overload. When the circuit fails or is abnormal, the current will continue to rise, which may damage important components in the circuit, burn the circuit or even cause a fire. The fuse will fuse itself and cut off the circuit when the current abnormally rises to a certain height and heat, thereby protecting the safety of the circuit.
