H.R.C. fuses provide best protection against________________?
Correct answer: D. short-circuits
- A. overload
- B. reverse current
- C. open-circuits
- D. short-circuits
Explanation
An H.R.C. fuse has a high rupturing capacity, so its enclosed fuse element and filling can safely interrupt very large fault currents. It is therefore especially effective against short-circuit currents.
