What is AC MCB?
Alternating current, also known as 60hz or 60 cycles per second, is what drives the power grid. The voltage alternates between +V and -V, changing 60 times per second. A voltage of 0 volts occurs 60 times per second at a certain point. The AC miniature circuit breaker will disconnect at this 0v point, extinguish the arc, and protect the circuit from excessive current.
There are many types of AC miniature circuit breakers on the market. However, the correct MCB should be selected according to the place of use.
