How circuit breakers are classified?

There are different ways of classifying circuit breakers.However,the general way is by the medium used for extinction of arc.While circuit breaker opens, an arc is formed between fixed and open contacts.The circuit breaker is considered to be of good quality if it extinguishes the arc fast.The following are the types of circuit breakers.

Oil Circuit Breakers - Uses insulating oil as arc extinguisher

Air Blast Circuit Breaker- Uses high pressure air blast as arc extinguisher

SF6  Circuit Breaker - Uses SF6( sulphur hexa  fluoride gas ) as arc extinguisher

VCB(Vacuum Circuit Breaker)  - Uses vacuum for arc extinction
