Why do fuses need to be protected during a short circuit?
1. Considerable time is lost in rewiring or replacing a fuse after operation. 2. On heavy short-circuits, discrimination between fuses in series cannot be obtained unless there is sufficient difference in the sizes of the fuses concerned. 3. The current-time characteristic of a fuse cannot always be co-related with that of the protected apparatus.

What happens to a fuse during a fault?
• Under normal load conditions, the fuse element is at a temperature below its melting point. Therefore, it carries the normal current without overheating. • When a fault occurs, the current increases and the fuse element melts before the fault current reaches its first peak. • The heat produced in the process vaporizes the melted silver element.
