advantages.
1: they are capable to carry high as well as low fault current.
2: they don't deteriorate with the age.
3: they have high speed of operation.
4: they don't need any maintenance.

What is the difference between semiconductor fuse and high rupturing capacity fuse?
Devices such as transistors, IGBT, thyristors in order to protect them the rupture time is in msec. HRC fuses rupture time is more and the current for rupturing is also high making it suitable for motors/resistive loads.
What are the advantages of a HBC fuse over a cartridge fuse?
HBC (High Breaking Capacity, European term) and HRC (High Rupturing Capacity, North American term) fuses have the ability to break high fault currents. This is done by having silica sand in the fuse that the fuse elements travel through. On high fault current that sand will melt and turn to glass. This breaks the current flow immediatelyA cartridge fuse maximum current breaking capacity is very much lower than HRC, HBC because there is nothing in the fuse body except the fuse elements.
What is the main disadvantage to using fuses?
fuse is a conductor having a particular current capacity. it burns when current through fuse is more than its capacity. its disadvantages are 1. it is for one time use. 2.In many types of fuses you have to swith off main power to replace the fuse.
What the mean by hbc fuses?
High Breaking Capacity
What are the advantages and disadvantages of fuses?
On the advantage side, fuses are simple, easy, no maintenance required and low cost if compared to circuit breakers. They will clear a fault quicker than a breaker, trip curve not affected by ambient air temperature. On the disavantage side, fuses may cause single phasing and motor failure and they need replacement after every fault clearing.
Is a T2AH fuse the same as a T2L?
No. A T2AH fuse is a high-breaking capacity type whereas a T2L is low-breaking capacity. Often, High-breaking capacity fuses have ceramic (hence stronger) tubes and low-breaking capacity fuses have glass tubes. High-breaking capacity fuses are able to protect against higher short-circuit currents than low-breaking capacity ones (which could explode under the same conditions).
What is a Heterophagosome and a Autophagosome?
heterophagosome is formed when a lysosome fuses with another vescicle within the cell and causes its digestion. autophagosomy is when the lysosome digests the whole cell by rupturing to release its enzymes.
What is meant by rapture capacity as in HRC fuses?
HRC stands for 'high rupture capacity'. An alternative abbreviation is 'HBC, meaning 'high breaking capacity. The rupture (or breaking) capacity is a term describing the maximum short-circuit current that the fuse can safely interrupt at its rated voltage. Most fuses will safely interrupt any level of fault current between a current that just causes the fuse to operate (melt), up to their maximum breaking capacity- such fuses are called 'full-range'. HRC fuses usually have strong, ceramic bodies to withstand the huge pressure generated when the fuse has to interrupt a large short-circuit current. In contrast, low breaking capacity fuses have weaker bodies made from materials such as glass.
Various types of fuses mcb how they work?
From Transmission and Distribution Electrical Engineering, Third EditionFuses act as a weak link in a circuit. They reliably rupture and isolate the faulty circuit under overload and short circuit fault conditions so that equipment and personnel are protected. Following fault clearance they must be manually replaced before that circuit may be put back into operation. Striker pins are available on some designs such that remote alarms may be initiated on fuse operation. Miniature circuit breakers (MCBs) or moulded case circuit breakers (MCCBs) are also overcurrent protection devices often with thermal and magnetic elements for overload and short circuit fault protection. Earth leakage protection, shunt trip coils and undervoltage releases may also be incorporated in the designs. As a switch they allow isolation of the supply from the load. Normally the MCB requires manual resetting after a trip situation but solenoid or motor driven closing is also possible for remote control. This chapter describes the various types of fuse and MCB together with their different uses and methods of specification. Examples and calculations for correct selection of different applications are also given. == Table 11.1 gives a summary of different fuse types, their uses, advantages and disadvantages. Table 11.2 summarizes some current relevant standards covering fuses. There are various categories ranging from subminiature electronic and solid state device protection fuses, power types (expulsion and high rupturing capacity (HRC)) to 72 kV. {| |+ Table 11.1: Summary of fuse types !

Advantages and disadvantages of fuses?
Advantage: a fuse is guaranteed to pop only when too many amps are pulled, unlike a circuit breaker that may be "accidentally" turned off by some practical joker. Disadvantage: You must have spares on hand (or go buy them when needed) unlike a circuit breaker which can be reset over and over.
What are the disadvantages of using fuses?
Once it blows, you will have to replace it before the circuit will work again. If you don't have a spare on hand then you'll have to get one as soon as possible.
What is the differ between a ceramic fuse and glass fuse?
Typically, glass fuses have a low breaking capacity, while ceramic ones have a high breaking capacity. This is to help protect the surrounding circuits from molten material. And maybe the technician.
