Question
what is the difference between MCB and MCCB?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
MCB is miniature circuit breaker which is a small
electrical circuit breaker used in small electrical systems
for protection against conditions such as overload or short-
circuit.

MCCB is moulded case circuit breaker which can be operated
upto currents of 1000 A.

# 2
mcb-miniature circuit breaker its bi metal trip type cannot able to co-ordinate the relays,small size,using for small loads.

Mccb-Moulded case circuit breaker can able to co-ordinate relays,here trip coil is separately provided for tripping action,large size and using for heavy duty
