    The largest value of current that the breaker can carry = Imax=35.4A

    Explanation:

    Rms value of current = Irms = 25 A

    The rms current and the maximum current are related as

    Imax = √2 Irms

    Imax=√2 (25)

    Imax=35.4 A

    Thus the maximum current carried by the breaker = 35.4 A
