The fusing factor of HRC fuse isa)1.8b)1.5c)1.1d)1.4Correct answer is ...
The fusing factor of HRC fuse is 1.1.
Explanation:
- HRC stands for High Rupturing Capacity. It is a type of fuse used to protect electrical equipment from overcurrents.
- The fusing factor of a fuse is the ratio of the minimum melting current to the rated current of the fuse.
- The minimum melting current is the minimum current at which the fuse element melts and opens the circuit.
- The rated current of the fuse is the maximum current that the fuse can carry continuously without overheating.
- The fusing factor of HRC fuse is generally 1.1, which means that the minimum melting current is 1.1 times the rated current of the fuse.
- For example, if the rated current of an HRC fuse is 10A, then the minimum melting current would be 11A (10A x 1.1).
- The higher the fusing factor, the more sensitive the fuse is to overcurrents and the faster it will blow. However, a higher fusing factor may also increase the risk of nuisance tripping (i.e. the fuse blowing unnecessarily).
- HRC fuses are commonly used in industrial applications and have a high breaking capacity, which means they can safely interrupt high fault currents without causing damage to the equipment or surroundings.
