VACUUM CIRCUIT BREAKER:
A vacuum circuit breaker is a kind of circuit breaker where the arc quenching takes place in vacuum medium. These are used in 11kV and more.
AIR CIRCUIT BREAKER:
A vacuum circuit breaker is a kind of circuit breaker where the arc quenching takes place in air medium. These are used in 440V.
MOULDED CAST CIRCUIT BREAKER: An MCCB provides protection by combining a temperature sensitive device with a current sensitive electromagnetic device. These provide protection against Thermal Overload, Short Circuits and Earth Faults.
RESIDUAL CURRENT CIRCUIT BREAKER:
These are aimed to protect people from the risk of electrocution and fire that are generally caused due to the faulty wiring. An RCCB is also very useful when a sudden earth fault occurs in the circuit.
RESIDUAL CURRENT CIRCUIT BREAKER WITH OVERLOAD PROTECTION:
This is a combination of RCCB and MCB. It provides protection against overload, short circuit, earth fault and electrocution.
MINIATURE CIRCUIT BREAKER: An MCB provides protection against overload current and short circuit only
EARTH LEAKAGE CIRCUIT BREAKER:
This provides protection against earth faults only.
