What is the Difference Between MCCB & ACB & VCB
Answer Posted / shahnawaz
MCCB,VCB,ACB all are of different type with same
functioning.
all of them are used to isolate the power or to trip the
power at the time of fault in line and thus save the
circuit from further damage and isolate unheathy part from
healthy one.
if the circuit if of low rating we can go ahead with MCCB
but for high rating circuit we go for costlier CB that is
ACB/VCB because they are more reliable and have long life.
