Electronic type intelligent miniature circuit breaker

The utility model discloses a circuit breaker, in particular an electronic type intelligent miniature circuit breaker. The electronic type intelligent miniature circuit breaker is characterized in that the circuit breaker comprises a make-and-break mechanism, a data detection mechanism, a data processing mechanism and an electric execution mechanism which are connected with a main circuit, wherein the data processing mechanism adopts a singlechip; the electric execution mechanism adopts a motor and an executing mechanism which are connected; the signal input end of the singlechip is connected with the data detection mechanism; the signal output end of the singlechip is connected with a driving circuit of the motor; and the executing mechanism is mechanically connected with the make-and-break mechanism. The electronic type intelligent miniature circuit breaker is an electronic type automatically-controlled intelligent circuit breaker converted from the traditional mechanical circuit breaker; when the faults of short circuit, overcurrent, current leakage, undervoltage, phase failure and the like are generated in the circuit, the electric executing mechanism is controlled through the data detection signal to enable the circuit breaker to cut off a main circuit, and the on-off of the circuit breaker can be manually controlled through a remote control switch; and the circuit breaker has the advantages of convenience for operation and high safety.
