An MCB (Miniature Circuit Breaker) is typically designed for AC (Alternating Current) circuits. MCBs are used to protect electrical circuits from overload or short circuits, and most of them are rated for AC.
However, there are MCBs specifically designed for DC (Direct Current) circuits as well, but they are less common. DC circuits require different characteristics in the breaker due to the nature of current flow (constant direction), which can make it harder to interrupt the current compared to AC.
So, in general, unless you're working with DC systems, the MCB you're using is likely for AC.
