[Scope of application] When there is a fault or abnormality in the circuit, the current will continue to increase, and the increased current may damage some important components or valuable equipment in the circuit, or even cause a fire. Fuses are used to protect electronic devices from damage due to high current and also to avoid serious damage caused by internal faults in electronic devices. Therefore, each fuse has a rated value, and when the current exceeds the rated value, the fuse will blow. If the fuse is properly placed in the circuit, when the current abnormally rises to a certain height and temperature, the fuse will cut off the current on its own, protecting the safe operation of the circuit and reducing damage to the equipment.
