The interruption capacity of a fuse is the ability of a fuse to stop the current flow on a short circuit condition. On high rupture capacity (HRC) fuses the fuse cartridge has silica sand surrounding the fuse link. When the link blows under a high current so much heat is generated that the silica sand actually turns to glass to extinguish the arc. A dual element fuse is used on motor starting circuits. Their construction inside with two current flow paths allow the high current of a motor start for a short interval of time without blowing.

What is full form of HRC fuse?
High Rupture Capacity fuse.
Why you are indicating capacity of transformer in KVA?
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
What is a gG fuse?
a gG fuse is general purpose low-voltage (i.e. less than 1000Vac) fuse with full-range breaking capacity (it will safely interrupt all currents from the minimum fusing current up to its maximum breaking current).
What does the letter l mean in t 6.3al250v?
6.3AL250V are markings on a fuse. 6.3 (A)mperes (L)ow Breaking capacity 250 (V)olts
What is current choking in transformers?
The "current choking" means that the maximum capacity of a transformer is not being utilized. To prevent it from ever reaching its maximum capacity a lower value of over current protection or fuse is installed. The purpose is to use larger capacity transformer available but using smaller distribution and cables just sufficient for the application to lower the installation cost.
What is an interrupting rating on a fuse?
It should have a code identifying what kind of fuse it is, which can be looked up.
Will it work if you replace a 1.25 amp 125 volt fuse with a 1 amp 250 volt fuse?
Yes you can do that as long as it will fit in the fuseholder. It is acceptable to replace a lower Voltage Rated fuse with a higher but NEVER replace a higher with a lower. There are several things to consider when replacing a fuse: 1) The minimum voltage rating of the fuse is equal to or higher than the voltage of the circuit you are placing it in 2) The Amperage rating of the fuse does not exceed the capacity of the circuit you are trying to protect. Always replace a fuse with one that has the same amperage rating. 3) The interrupting rating of the fuse is sufficent for the capacity of the circuit supplying the fuse. If replacing a fuse always use one with an interrupting capacity equal to or greater than the fuse you are replacing.
How the capacity of fuse is determined?
The capacity of fuse is determined by the load current.
What sort of fuse would you select for an installation that required high current interrupting ability and an allowance for instantaneous over currents?
The best type fuse for an installation that required high current interrupting ability and an allowance for instantaneous over currents, would be the largest fuse sufficient for normal use and a relay to another fuse for the over currents. It is always best to consult an electrician.
What does the boat capacity plate indicate?
the safe load carrying capacity
Why does my Porsche keep blowing a fuse?
Blown fuses generally indicate a short in the wiring. Sometimes the component that the wire is going to is shorting out. If the specs call for a certain rating of fuse, say 15 amps and you put in a smaller capacity fuse, like 5 amps it will keep blowing because you have the wrong fuse installed.
What is full form of HRC fuse?
High Rupture Capacity fuse.
Why does a fuse blow?
A fuse blows when the current draw of the circuit is greater than the capacity of the fuse.
How do you find fuse capacity in house lightning?
To find the circuit's capacity you have to look at the breaker or fuse that protects that circuit. On the handle of the breaker you will see a number. that number is the tripping capacity of that particular breaker. On a glass screw in fuse you will see a coloured disk with a number on it that is the capacity that the fuse can handle before opening the circuit. On cartridge fuses the voltage and amperage rating will be printed on the body of the fuse.
Where does a capacity plate indicate?
Safe load limit
BE-5 what does a capacity plate indicate?
safe load
Can a 250V 2.5A fuse replace a 125V 2.5A fuse?
Yes, a 250V fuse can replace a 125V fuse if they have the same ampacity rating. The voltage rating is simply the maximum voltage that the fuse is capable of safely interrupting. You can go higher, but you can not go lower. Obviously, the form factor of the fuse must be the same, but that is often the case.
