Quick answer
A breaker trips on overload or a short circuit; an RCD (earth leakage switch) trips when current leaks to earth, often from a faulty appliance, wet socket or damaged cable. Unplug everything, reset, then plug items back one at a time. If it trips with everything unplugged, the fault is in the wiring and needs an electrician.
