The power grid alternates at a frequency of 60 Hz or 60 cycles per second; hence the name “alternating current”. The voltage alternates between +V and -V, changing 60 times per second. This means that at a certain point the voltage is 0v, 60 times per second. The AC MCB will “disconnect” the connection at this 0v point, extinguish the arc, and protect the wiring from too much current.
There are many types of AC MCB on the market. However, the correct MCB should be selected according to the place used.
