I think u want to know the difference of application
between ACB and MCB!
ACB- Air circuit breaker. it is used at incomming after
transformer secondary, b'coz at secondary side current is
more unless load is not distributed. ACB protects the
system without occuring any fault while switching on and
off of supply. B'coz it consists some mechanism to quench
the arc while occuring in system. it can used at 2500 amps.
where as in MCB(Miniature circuit breaker) there is inner
mechnism to quench the arc while operating at high
currents.that why ACB is suitable for high currents in
system.
