The earth fault, caused by an insulation loss between a live conductor and an exposed conductive part, represents a plant engineering problem that may cause damage to the electrical installations and above all may jeopardize people; as a matter of fact, people could get in touch with an exposed-conductive-part not normally live but which, due to the fault, might have a dangerous potential to ground. Therefore, the solution against this fault is a circuit breaker.
