As far as I know 220-240V RCD's and MCB's will work fine on 110V. I think circuit breakers are voltage ignorant as far as their functioning goes but maybe wait for a second opinion. They have a maximum voltage rating but that would be determined by their insulation properties for safety purposes. I'll check in my reference books tomorrow and confirm if nobody else does before me.
