Explanation:

  • The fusing factor is a measure of the ratio of the melting current to the rated current of a fuse.

  • The value of the fusing factor determines the time it takes for the fuse to blow or melt when there is an overcurrent.

  • If the fusing factor is greater than 1, it means that the fuse will blow or melt at a current higher than its rated current, and hence it will take more time for the fuse to blow or melt.

  • If the fusing factor is less than 1, it means that the fuse will blow or melt at a current lower than its rated current, and hence it will blow or melt faster.

  • Therefore, the value of the fusing factor is always more than 1 as it is desirable for the fuse to take some time before it blows or melts when there is an overcurrent.

  • If the fusing factor is equal to 1, it means that the fuse will blow or melt exactly at its rated current.

  • If the fusing factor is equal to 0, it means that the fuse will not blow or melt at all, even when there is an overcurrent.
