Unless I've missed it, the important question of is it an over current or leakage trip hasn't been answered?
Take not of the little flag window on the RCD. It will change (to red I think) for an leakage trip vs no colour change for over current trip.
You need to understand why it tripped before getting into changing breakers, etc.
