fuse

A current protection device. When the current in the circuit exceeds the rated current of the fuse, it will melt due to overheating, thereby cutting off the circuit and preventing serious consequences such as fire and damage to electrical equipment due to overload or short circuit. Fuses are made of metals or alloys with lower melting points, and different specifications correspond to different rated currents. Fuses with specifications such as 10A and 15A are commonly used. When selecting a fuse, you need to select it based on the normal operating current of the circuit to ensure that its rated current is slightly greater than the normal current of the circuit to ensure safe and stable operation of the circuit.
