Fuse repture as a result of gradual overheating - Video

 

 

 

 

 

 

 

 

 

 

 

 

 

Notice that when the current is low, the fuse operates normally.

This demonstrates that a fuse operating at its rated current will operate indefinitaly.

When the current is increased beyond the rated current of the fuse, the fuse will change by causing the wire to expand and heat up to a point that it will blow.

This automatically causes an interruption in the circuit supply of current.

A fuse is designed to be the weakest link in the circuit, thus protecting every other part of the circuit from overheating and blowing, just like the fuse did.
