    摘要： A crossbar structure of an electromagnetic contactor is provided, specifically, a crossbar structure of an electromagnetic contactor in which consistent performance is attained by preventing a moving mount from being flipped. The electromagnetic contactor includes a crossbar configured to move up and down and a moving contact point disposed on an installation groove, which is formed on the crossbar in a vertical direction, and brought in contact with or separated from a fixed contact point. The installation groove includes an insertion part into which the moving contact point is inserted and assembled and an operating part closely formed enough to prevent the moving contact point from being flipped when the moving contact point moves up and down.

    摘要： A reset knob 20 is mounted to a tip end of a shaft 16. A torsion spring 21 and a returning motion-preventing lock 22 are bent and accommodated in the reset knob 20. The returning motion-preventing lock 22 can rotate around a reset-knob fulcrum 20a of the reset knob 20 by a load of the torsion spring 21. Therefore, the returning motion-preventing lock 22 jumps out from inside of the reset knob 20 which is firmly connected together with the shaft 16 by a force of the torsion spring 21, thereby preventing the shaft 16 and the reset knob 20 from returning to an initial position. Further, since the returning motion-preventing lock 22 can easily be accommodated in the reset knob 20 manually, a reset operation for returning the shaft 16 to its original initial position can be carried out easily.

    摘要： A switch unit, preferably implementing a circuit breaker, includes a contact slide unit formed by a contact slide, a fixed contact piece and a moveable contact piece), and a short-circuit release that acts to displace the moveable contact piece by means of a tappet in the event of a short-circuit. A moveable braking device is configured and arranged such that, following circuit opening displacement of the moveable contact piece in response to a short-circuit, the moveable brake device dampens the return, rebound movement of the moveable contact piece to reclose the circuit.

    摘要： A reversal prevention mechanism for an electrical switching apparatus, such as a circuit breaker, includes an actuator assembly pivotably coupled to the circuit breaker housing, a first stop element for controlling movement of the actuator assembly, a stop assembly pivotably coupled to the housing, and a second stop element for controlling movement of the stop assembly. The stored energy mechanism is movable among a charged position, a discharged position, and a contact touch position corresponding to a point at which the circuit breaker separable contacts make initial electrical contact. When the stored energy mechanism is disposed in the contact touch position, the stop assembly cooperates with the actuator assembly to prevent the stored energy mechanism from moving backwards.

    摘要： A drive for an electric high voltage circuit-breaker has a revolving crank that is driven by an energy storage mechanism, such as a spring, between an upper dead center and a bottom dead center and a backstop that prevents the crank from moving backwards against the driving direction after it moves beyond the bottom dead center. The backstop is provided with a friction clutch with a first ring that is firmly coupled to the crank and the driving shaft and that can rotate in relation to a second return stop ring when a releasing force is exceeded.
