A fuse is an electrical safety device that operates to provide overcurrent protection to an electrical circuit. Although it’s an economically available, standalone protection device, yet few disadvantages are associated with it. Given below is a list of a few of them.
- A fuse requires replacement after every operation by the course of which considerable time is lost in rewiring or replacing
- Under heavy short circuits, discrimination between fuses in series cannot be obtained unless there is sufficient difference in the sizes of the fuses concerned.
- The current-time characteristic of a fuse cannot always be correlated with that of the protected apparatus
