Regarding HRC fuses which of the following statement is not correct?a)...
In HRC (High Rupturing Capacity) fuse, the fuse wire or element can carry short circuit heavy current for a known time period. During this time if the fault gets removed, then it does not blow off. Otherwise, it blows off or melts.
- They do not deteriorate with time
- They have inverse time-current characteristics
- Operation of the fuse is very reliable
- It is required to be replaced after each operation

Regarding HRC fuses which of the following statement is not correct?a)...
HRC (High Rupturing Capacity) fuses are used in electrical systems to protect against short circuits and overloads. They are designed to interrupt the flow of current in the event of a fault, thereby preventing damage to the system and reducing the risk of fire.
Let's analyze each statement to determine which one is not correct:
a) They do not deteriorate with time:
This statement is correct. HRC fuses are made of high-quality materials that are resistant to deterioration over time. They are designed to have a long lifespan and maintain their performance throughout their operational life.
b) They have inverse time current characteristics:
This statement is correct. HRC fuses have a characteristic known as inverse time current characteristics, which means that the time it takes for the fuse to blow decreases as the current increases. This characteristic allows the fuse to protect the system against both short circuits and overloads.
c) Operation of the fuse is very reliable:
This statement is correct. HRC fuses are known for their reliable operation. They are designed to provide consistent and predictable performance, ensuring that they trip when necessary to protect the system. This reliability is crucial in maintaining the safety and integrity of the electrical system.
d) It is not required to be replaced after each operation:
This statement is not correct. HRC fuses are designed to be a one-time use device. Once they have operated and blown, they need to be replaced to restore protection to the system. This is because the fuse element inside the fuse is designed to melt and break when subjected to excessive current. Once this happens, the fuse is no longer functional and must be replaced.
In conclusion, the correct answer is option 'D' - It is not required to be replaced after each operation. HRC fuses need to be replaced after each operation to ensure the continued protection of the electrical system.
