Answer Posted / sunthosh080
All the above answers are correct and little more to add
from my side.
usually these breakers are used for short circuit
protection to a valid value.
The max. KA in MCCB is 50 KA and in ACB it is 100KA. So the
selection also depends on the short circuit level to be
protected.
Now a days all the breakers are microprocessor based
protections with all parameters.
