What is the types of circuit breaker

Types of Circuit breaker

     1. Low voltage circuit breaker

     2. Medium voltage circuit breaker

     3. High voltage circuit breaker

1. Low voltage circuit breaker

    Low-voltage (less than 1,000 V)

    Types .

1.    MCB

2.    MCCCB

3.    ACB

  2 . Medium voltage circuit breaker

        Medium-voltage circuit breakers rated between 1 and 72 kV.

Types

    Medium-voltage circuit breakers can be classified by the medium used to extinguish the arc .

1.    Vacuum circuit breakers—With rated current up to 6,300 A, and higher for generator circuit breakers

2.    Air circuit breakers—Rated current up to 6,300 A and higher for generator circuit breakers. Trip characteristics are often fully adjustable including configurable trip thresholds and delays. Usually electronically controlled, though some models are microprocessor controlled via an integral electronic trip unit .

3.    SF6 circuit breakers extinguish the arc in a chamber filled with sulphur hexafluoride gas.

3 .High  voltage circuit breaker.

   The definition of high voltage varies but in power transmission work is usually thought to be 72.5 kV or higher, according to a recent definition by the International Electrotechnical Commission (IEC)

Types

1.    Air blast circuit breaker

2.    Vacuum circuit breaker

3.    SF6 Circuit breaker

4.    CO2 Circuit breaker
