description A circuit breaker comprises a contact system and an operating mechanism, the contact system comprises a static contact, a main shaft and a moving contact, the operating mechanism comprises a handle assembly, a toggle linkage mechanism and a spring, and the toggle linkage mechanism is connected with the main shaft to transmit driving force of the operating mechanism to the contact system; the stopping mechanism is used for stopping the handle assembly from operating towards the opening position when the moving contact and the static contact are welded in a fusion mode, the stopping mechanism is arranged between the main shaft and the handle assembly, and when the moving contact makes contact with the static contact, the main shaft locks the stopping mechanism, so that a stopping part on the stopping mechanism is located on the motion trail of a stopping piece on the handle assembly, and the stopping piece moves towards the opening position. The handle assembly is prevented from moving towards the opening posit
