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.

Which type of circuit breakers used in railway applications in India?
Vacuum circuit breaker is used in railway applications and as it is used in the applications where current chopping phenomenon is more
Why Vacuum circuit breaker is using HT and why Air circuit breaker is using in LT?
Dielectric Strength of Vacuum is more than that of Air. In HT voltage is more than LT. So VCB is used in HT & ACB in LT. Rakesh Gaikwad
Can you use the vacuum circuit breaker instant of air circuit breaker?
Actually ACB isused for Low Tension side and VCB is used for High Tension Side..Chappa matter
What is the function of an LBB relay?
A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.
Which type of circuit breakers used in EHT applications?
SF6 circuit 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.
Which type of circuit breakers used in railway applications in India?
Vacuum circuit breaker is used in railway applications and as it is used in the applications where current chopping phenomenon is more
What is difference between VCB and ACB?
VCB (vacuum circuit breaker) is used in HV (high voltage) applications. ACB (air circuit breaker) is used in LV (low votage) applications.
Why Vacuum circuit breaker is using HT and why Air circuit breaker is using in LT?
Dielectric Strength of Vacuum is more than that of Air. In HT voltage is more than LT. So VCB is used in HT & ACB in LT. Rakesh Gaikwad
A fuse or circuit breaker used in a circuit is usually inserted in?
A fuse or circuit breaker used in a circuit is usually inserted in series with the load.
Is a circuit breaker a resistor?
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
What device is used as a form of safety device in an electrical circuit?
A fuse or circuit breaker will fit this description.
What device is used for turning a circuit on or off?
Circuit breaker or switch
What is a breaker and what is it used for?
An electrical breaker is a safety device used to open a circuit that has an electrical fault on it.
Why neutral is not required for vacuum circuit breaker?
Air-blast circuit breakers are used to disconnect high-voltage transmission or distribution circuits in the event of a fault. One circuit breaker is required for each of the three line conductors; there is not normally a neutral conductor in high-voltage three-phase transmission/distribution lines.
Can you use the vacuum circuit breaker instant of air circuit breaker?
Actually ACB isused for Low Tension side and VCB is used for High Tension Side..Chappa matter
Working principle of air circuit breaker?
circuit breaker is a switch that turned off when there is a short circuitAnswerAn air circuit breaker is a high-voltage circuit breaker whose tripping and closing mechanisms are (usually) operated pneumatically, and whose arc is extinguished by a blast of air -hence the alternative name 'air-blast circuit breaker'.
