  • Switchgear manual control plug racking interlock structure
    Patent number: 9490612
    Abstract: Interlock structure for a circuit breaker is constructed and arranged such that 1) when a control plug is disconnected from a socket, a portion of a linkage structure engages a racking linkage, causing a portion of the racking linkage to engage a racking screw, preventing the racking screw from rotating and thus preventing racking of the circuit breaker, and 2) when the control plug is connected with the socket, the linkage structure is actuated thereby moving the portion of the linkage structure to disengage from the racking linkage such that the portion of the racking linkage disengages from the racking screw, permitting the racking screw to rotate thereby permitting the circuit breaker to be racked to a connected position, where the primary contacts are connected to the main bus.

  • Coupling device for circuit breaker
    Patent number: 9484167
    Abstract: Disclosed is a coupling device for a circuit breaker. A third coupler formed as a curved surface is provided between a first coupler coupled to an outer handle assembly, and a second coupler coupled to an inner handle. Under such configuration, even if the inner handle and the outer handle assembly are not concentric with each other, the third coupler may transmit a rotational force applied to the first coupler to the second coupler in a direction perpendicular to a shaft direction of the second coupler, in a state where the third coupler is inclined from an upper surface of the circuit breaker body. As a result, a user's force to rotate the outer handle can be transmitted to the inner handle. This can prevent a malfunction of the circuit breaker, and thus can enhance reliability of the circuit breaker.

  • Trip bar stop
    Patent number: 9466441
    Abstract: An operating mechanism including a number of biasing elements and a number of linkage members is provided. The linkage members are operatively coupled to each other and each are movable between a second configuration, an initial tripped configuration, a rebound configuration, and a final tripped configuration. The biasing elements are operatively coupled to the number of linkage members and bias the number of linkage members to the final, first configuration. A stop member is coupled to one of the linkage members. The stop member moves with the associated linkage member. The stop member is positioned to contact a stop surface when the linkage members are in the rebound configuration. Contact between the stop member and the stop surface substantially arrests the motion of the linkage members.

  • Low current switch
    Patent number: 9431193
    Abstract: A low current switch has a flexible movable contact that can be deflected by an actuator. In some implementations the switch may permit a low current switch to be manufactured using elements of a high current switch without requiring large amounts of precious metal. The flexible movable contact may be arranged as one or more cantilevers that are deflected using a rocking actuator. The actuator interacts with the movable contact in such a way as to provide tactile feedback to an operator comparable to a high current switch having a rigid movable contact. Also described are a set of low and high current switches, components of a low current switch, and a method of manufacturing a low current switch.
