During short circuit the current increase more than the maximum limit.

As a result, the fuse metal vaporizes and the circuit is snapped.

A fuse wire is fitted in a porcelain casing because it ensures safety of the appliances and vaporization may cause fire, hence it is placed in the porcelain casing.
