There are different arc lengths for different types and size breakers. The length of the arc is governed by the physical distance of the contact openings and the efficiency of the arc chutes to extinguish the arc.
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'.
vcb is have vaccume and sf6 cb is filled with sf6 gas which will have good arc quencing property
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.
The neutral is in contact with the ground at some point of the circuit.
You can't change the one breaker, but you can't use two separate arc fault breakers unless you separate the neutrals. However double pole arc fault breakers are made for this purpose and the common neutral would be O.K.
The proper ampere rating of a circuit breaker for an electric arc welder depends on the arc welder. Each is different. Look at the nameplate on the arc welder and choose the circuit breaker and wiring accordingly.
I'm not aware of any device called an 'oil breaker transformer'.However, an oil circuit breaker or, more correctly, an 'oil-filled circuit breaker' is one of several types of circuit breaker used in high-voltage systems. The oil has two functions: (1) it is a far better insulator than air, enabling the circuit breaker to be far more compact (reducing its 'footprint'), and (2) the oil is used to extinguish the arc when the circuit breaker trips under fault conditions -a jet of oil removes ionised contaminants from the arc path, lengthens and 'snaps' the arc, and cools the arc.
A vacuum circuit breaker is a high-voltage circuit breaker whose contacts separate within a vacuum dielectric. The vacuum contributes to extinguishing the resulting arc because ionisation cannot take place while the arc is stretched between the separating contacts.
You may be referring to an air circuit breaker or, more accurately, and air-blast circuit breaker. This is a type of high-voltage circuit breaker in which the electrical arc, drawn when it opens, is stretched and snapped by a blast of air directed between the separating contacts -so the air is used as a method of extinguishing the arc. Often, these breaker's mechanisms are also driven by compressed air.

ARC VOLTAGE is the voltage that appears across the contacts of circuit breaker during the arcing period, during which the current flow is maintained in the form of an arc. The arc voltage value is low except for the point at which the current reaches zero when the arc voltage rises rapidly to a peak value.

Check the nameplate on the actual breaker. Some breakers are rated for AC or DC. If it doesn't specifically list DC on the nameplate, then no, you should not rely on the breaker to adequately protect the circuit.
You can't change the one breaker, but you can't use two separate arc fault breakers unless you separate the neutrals. However double pole arc fault breakers are made for this purpose and the common neutral would be O.K.
"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.
