Why copper can not replace the fuse

Answer:

The fault current of the circuit where the fuse is placed must be less than the rated breaking capacity specified by the standard. Otherwise, when the fuse blows, there will be continuous arcing, igniting, and igniting the fuse.

Each fuse has a rated size, and the fuse will blow when the current exceeds the rated specification. When the current between the conventional non-fusing current and the rated breaking capacity specified by the relevant standard acts on the fuse, the fuse should

Then the fuse will rise in the current to a certain height and a certain time, their own fuse cut off the current, which play a protective circuit to the safe operation of the role

When the circuit fails or abnormal, accompanied by rising current, and the rising current may damage some important devices in the circuit or expensive devices, it is possible to burn the circuit or even cause a fire.If the circuit correctly placed the fuse ,

Copper wire has a small resistivity and is not easy to blow.
