What are the high rupturing capacity fuse and advantages and disadvantages?
Advantages of HRC Fuse: It clears high as well as low fault currents. Do not deteriorate with age. Having high-speed operation. Provides reliable discrimination.
What is high rupturing capacity HRC type fuse?
Definition: HRC fuse (high rupturing capacity fuse) is one kind of fuse, where the fuse wire carries a short circuit current in a set period. HRC fuse is consistent & it has the feature like if it has a high fault current then break time is low. Similarly, if the fault current is not high, then break time is long.
What is HRC fuse full form?
HRC(High Rupture Capacity) Fuse is the fuse used for protecting of electrical devices from short-circuit faults. HRC fuse have capacity to carry higher short-circuit currents.
What is rupturing capacity of fuse?
Rupturing capacity of a fuse means the maximum power a circuit breaker can interrupt under a fault.
Which of the following is advantage of HRC fuse?
Advantages of HRC fuses : They are capable of clearing high as well as low fault currents. They do not deteriorate with age. They provide reliable operation. They are cheaper than other circuit interrupting devices of equal breaking capacity.
What is a high rupturing capacity fuse?
HRC Fuse (High Rupturing Capacity Fuse) and its Types This type of fuse contains a fuse wire in it, which carries the short circuit current safely for a given time period. During this period, if fault is removed, then it does not blow off otherwise it will melt and remove the circuit from electrical supply hence, the circuit remains safe.
What is the maximum ampere rating of HRC fuse?
Preferred rating of HRC fuses are 2, 4, 6, 10, 16, 25, 30, 50, 63, 80, 100, 125, 160, 200, 250, 320, 400, 500, 630, 800, 1000, and 1250 amperes. High rupturing capacity HRC fuses High Capacity HRC Cartridge Fuses This type of fuse was developed by General Electric Company.
What are the advantages and disadvantages of HRC fuses?
Used for protection of Transformers, Motors and automobile, etc. After reviewing the advantages and disadvantages of H.R.C fuses for low voltage installation, which can be easily replaced. They provide high-speed operation in short circuit and over current protection.
What is the purpose of a hhrc fuse?
HRC Fuses are also used for protection on low voltage distribution systems against overload and short circuit conditions. NH fuse provides overload and short circuit protection for low and medium voltage.
