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

I have carried out wiring for lighting in a shed in Industrial area which contains Metal halide lamps & have balanced in 3ph.Now when we put all the lines on in the daytime the current taken at 3phases at MCB comes to be equal i.e.28,29,28Amps respectively but in the night time i.e between 7p.m.to 11p.m. at the same MCb the current is 52,59,62Amp, though I have fit 63A MCB it is tripping in the above period.What may be the reason.? Note: This industry is located in industrial area where majority of steel ingot manufacturing plants are there. Whether this may be due to harmonic? what should I do to overcome above problem.pl suggest urgently.   4
