circuit breakers are switches that open quickly usually opening with a fault condition
air circuit breakers need a long path to quench the arc
oil filled circuit breakers quench arcs much more effectively and in a smaller space
vacuum breakers have no media for an arc to propagate and are far smaller
fuses generally are filled with silica sand to quench the arc
and higher currents make the arc path much longer
typical AIC
fuses 200,000A
air breakers 15,000A
oil breakers 50,000A
vacuum breakers 100,000A
fuses work once and work correctly and dont fail or weld closed
they are inexpensive and safe
breakers can work tens of times
breakers need rework and recalibration whenever they are reset
breakers have mechanical moving parts tempered springs and require periodic maintenance and testing
Breakers can weld shut with a short

∙ 11y agoAn 'air-blast' circuit breaker is just one of several designs of high-voltage circuit breaker. It uses a blast of air to stretch and snap the arc created when the main contacts part. Air-blast breakers are normally outdoor breakers and, in the UK at least, are used in circuits of 33 kV and above.

What is air circuit?
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.
What is the difference of a Circuit Breaker from an Air Circuit breaker?
They are completely different. A moulded-case circuit breaker is a low- or medium-voltage device, whereas an air circuit breaker is a very large circuit breaker designed for use in high-voltage transmission/distribution substations.
What do you mean by acb and vcb?
acb means AIR CIRCUIT BREAKER ,& vcb means VACUUM CIRCUIT BREAKER
How do you convert 50Hz to 60Hz Air Circuit Breaker?
You don't.
How can a circuit breaker be made to work after it has opened?
put your dick in it
How do you work air circuit breaker?
There are various to check if your air circuit breaker working. You can use various tools that are available to test your air circuit breaker. A clamping ammeter is ideal for this purpose.

What is the acceptable value of contact resistance in 415V air circuit breaker?
415v air circuit breaker acceptable value of 0.01 ohms and lessthan
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.
Do air conditioners need there own circuit breaker?
Yes. Due to their higher current requirements it is recommended that air conditioners be connected to their own dedicated circuit and thus have their own 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.
Will a circuit breaker be the cause of an air conditioner not turning on?
It is possible if the circuit breaker has tripped or is faulty. The best way to check is by unplugging the air conditioner, and plugging in a table lamp. If the lamp lights up, then you know that the circuit breaker is working, if not then it is faulty.
How many coils in air circuit breaker?
There are three coils in Air circuit breaker.. 1.Solonoid coil 2.Moving coil 3. fixed coil
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'.
How do you convert 50Hz to 60Hz Air Circuit Breaker?
You don't.
