The intelligent circuit breaker usually consists of a circuit breaker main body and an electric operating mechanism, and the electric operating mechanism is used to control the switching action of the circuit breaker.

[0003] Problems existing in the existing intelligent circuit breakers:

[0004] At present, the connection method between the circuit breaker main body and the electric operating mechanism of most intelligent circuit breakers on the market is relatively traditional, that is, electrical connection needs to be carried out by disassembling the shell and wiring between the two. This connection method has the following disadvantages:

[0005] Inconvenient wiring: Since it is necessary to disassemble the shell for wiring, it is relatively cumbersome and time-consuming during installation or maintenance.

[0006] Low safety: During the wiring process, it may be necessary to contact the exposed wires, increasing the risk of electric shock.

[0007] Not easy to replace: When it is necessary to replace the circuit breaker main body or the electric operating mechanism, due to the complex wiring process, the replacement difficulty increases.

[0008] In view of the above problems, it is necessary to propose a new connection scheme to simplify the connection process between the circuit breaker main body and the electric operating mechanism, improve the installation and maintenance efficiency, and ensure the safety and reliability of the connection.
