What is MCCB ( Molded Case Circuit Breaker ) ?
It is a mechanical device ( BS 4752 ) to be used to connect and disconnect the circuit in normal and abnormal.Current rate for regular MCCB up to 3000 ampere.
It is only available in a 3 pole only, usually for a system that has a high ampere ratings in three ( 3 ) phase systems.For those who have ampere ratings than 400 ampere, the safety interlock system is prepared for security purposes because the current system are high.
There are two ( 2 ) types of MCCB commonly used in industry, it was: –
