VCB- This is known as Vacuum Circuit Breaker. In this
breaker vacuum is used as insulator and as an arc-quenching
medium VCB also used as a high voltage control switch. There
is no oil. Therefore will not occurring any fire problems in
this kind of circuit breaker. Vacuum circuit breakers in
particular are useful for controlling and protecting
electrical systems. Vacuum circuit breakers offer many
advantages as compared to other types of circuit breaker.
ABCB- This is known as Air Break circuit Breaker.ABCB is
used against very high current. Air circuit breakers are
commonly used in electrical distribution systems. Air
circuit breakers which include operating mechanisms that are
mainly exposed to the environment. ABCB is also protecting
for over load, short circuit and earth fault. Most of air
circuit breakers are use in indoor type substations.
