    Can an AC MCB be used in DC circuits?
    How can an AC MCB be used in DC circuits. How is the breaking capacity decided in an MCB?
    Does an MCB work in over and under load applications?

    Need to check the manufacturers specifications of the breaker you plan to use.

    Some are rated AC-DC, some are not.
