[0002] The intelligent switch circuit breaker is a modern power control and protection device. It not only has the basic functions of traditional circuit breakers, such as overload and short circuit protection, but also integrates intelligent monitoring and remote control capabilities. In daily use, the intelligent switch circuit breaker needs to perform detection operations within a unit time to determine whether the leakage protection module can work normally and ensure the stability of the structure. This operation usually operates the trip button on the switch touch button to connect the power supply to the coil structure of the release, thereby connecting the release, so that the push rod on the release moves to push the contact rod with the moving contact piece to swing, so that the moving contact piece is separated from the static contact piece to realize the opening operation.
