The present invention relates to a self-diagnostic circuit breaker having history information, driving data, and diagnosis information. The self-diagnostic circuit breaker comprises: a protection relay blocking a current which flows into a load; an attachable/detachable digital recording device detecting a surge current, which is generated when the circuit breaker is operated; and an external server analyzing the surge current to diagnose a contact state of a switch of the circuit breaker. The purpose of the present invention is to provide a self-diagnostic circuit breaker having driving data, and diagnosis information, and history information, which may guarantee highly reliable driving of the circuit breaker as much as possible. |
