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.

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
