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.


Is a switch a circuit breaker?

No. A circuit breaker is a switch, but a switch is not necessarily a circuit breaker. A "circuit breaker" is a device that will open the circuit when more current than it is designed for flows through the circuit. This is an automatic function, and does not require manual manipulation (such as a person physically moving an on/off switch). Resetting is often a manual function. <<>> If taken in the context of a switch opening a circuit or making a break in the circuit then the question, Is a switch a circuit breaker, then the answer would be, yes, as the switch does break the circuit.


What is the difference between air circuit breaker and MC CB?

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


Will a circuit breaker function properly if it is back fed?

Yes. The circuit breaker "does not care" which direction the current comes from. It is capable of protecting the circuit in any case.

What is the function of miniature circuit breaker?

The function of any electrical circuit breaker is to protect the conductor in the circuit that is connected to it. This prevents an amperage overload on the conductor. Different wire sizes have different amperage capacities, hence the reason for different breaker sizes.
