The advantages of a circuit breaker are:
they are smaller in size than fuses
better versions may have electronic trips so they can adjust trip curve to suite circuit design
easier for end user to reset (no touching live parts)
no waiting to reset (as with fuses - spare must be found)
no cost associated with resetting unlike cost of replacement fuses
easier when ground fault protection is needed
The disadvantages of a circuit breaker are:
they are more expensive than fused switches
when a circuit breaker trips, you lose all power (with fuses you only lose that phase)
harder to coordinate fault selectivity
harder and more costly to obtain high short circuit interrupting capacities

What gas is used in vacuum circuit breaker to quench the arc?
Sulpur Hexa-Fluoride(SF6) is the gas used to quench the arc in a Vacuum circuit breaker.SF6 is a inert gas and is in-organic,colorless,odorless,non-flammable gas used as an outstanding electrical insolater.AnswerAs its name suggests, the arc is extinguished within a vacuum. No gas is involved.

It makes a gas
What is the difference between transformer and transwitch unit?
Transwitch unit is a flameproof(FLP) wheel mounted transformer used in underground coal mines with inbuilt breaker on primary side and a protection chamber with circuit breaker on secondary side for overload and earth leakage provision. It can be moved easily from time to time as working face on mine advances. "flame proof apparatus" means an apparatus that can withstand without injury any explosion of the inflammable gas that may occur within it and can prevent the transmission of flame such as will ignite the inflammable gas which may be present in the surrounding atmosphere.
What are the disadvantage of technology?
What are the disadvantages of technology?there are non No, there is...technology can make people lazier; like children playing on the computer instead of studying, technology can make pollution; the smoke or gas of factories and cars, technology can harm the environment.The advantages and the disadvantages of technology are simple. A very good advantage of technology is that we can find out things about the solar system , or maybe we can find cures for cancer, or the swine flu. But also there are many disadvantages. Like it may cost a lot of money to get the technology to find out these things, or the answers or discoveries that the technology gives us, may not be always correct. Terrerist can use these technologies in destroying cities/towns.Everything in this world has advantages and disadvantages. What makes the difference is how to apply them properly, correctly.
Why you use surge arrestor in vcb are not sf6 cb?
Surge arrestors are used in vacuum circuit breakers (VCBs) primarily to protect the circuit from voltage surges caused by lightning strikes or switching operations. Unlike SF6 circuit breakers, which use insulating gas to limit the dielectric strength and manage transient voltages, VCBs rely on air as the insulating medium, making them more susceptible to overvoltage conditions. By incorporating surge arrestors, VCBs can effectively clamp transient voltages, ensuring the protection of both the breaker and connected equipment. This enhances the overall reliability and longevity of the VCB system.
What are the differences between a vacuum breaker and a SF6 gas circuit breaker breaker and a sf6 gas circuit breaker?
A vacuum breaker uses a vacuum to extinguish the arc when interrupting a circuit, while a SF6 gas circuit breaker uses sulfur hexafluoride gas. SF6 gas circuit breakers can handle higher voltages and currents compared to vacuum breakers. SF6 gas circuit breakers are also more environmentally harmful due to the greenhouse gas SF6, while vacuum breakers are considered more eco-friendly.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.

Is Sodium Hexa Fluoride Gas used in electrical circuit breakers?
yes SF6 gas is used in modern ckt. breaker.
What is the difference between Air circuit breaker and Vacuum circuiut breaker?
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.

What size amp circuit breaker should be used for a gas dryer?
Typical residential electric dryers are on 30 amp circuits, which means 10 gage copper wire. The circuit breaker should match the dryer cord rating, generally 30 amps.
