Question

why fuse of considerable rating is chosen instead of higher rating?​

Answer 1

fuse is taken a protecting device when exess current passes to the device .

if we are taking higher rating fuse the fuse will not break when exess current passes throug it

therefore our device will get damaged

so to protect our devices we want to take a fuse rate of considerable amount

i hope you understand this .

pls mark me as brain list

Answer 2

Low breaking capacity, so cannot be used in circuits with higher fault current levels. The fuse element is subjected to deterioration by oxidation through the continuous heating up of the element. This reduces the current rating of the fuse. Thus the fuse operates at a current lower than the rated value.

i hope it will help you
