The role of the fuse：When a circuit malfunctions or is abnormal, the
current is constantly rising, and the increased current may damage
some important components or valuable components in the circuit,

current when the current abnormally rises to a certain height and a
certain time, thereby protecting the safe operation of the circuit.
