    Abstract: A switching device including a frame, a first fixed contact member having a first contact area, and a first movable contact member having a first contact arm provided with a contact area. The first movable contact member is adapted to pivot relative to the frame around a first pivoting axis between a first position and a second position. The switching device includes a spreader member that is adapted to provide a first intermediate position for the first movable contact member in which a projection of the contact area of the first contact arm overlaps at least partially with a projection of the first contact area on a switch plane perpendicular to the first pivoting axis while the contact area of the first contact arm is spaced apart from the first contact area.

    Abstract: An electrical switching unit with separable contacts comprises a switching device comprising: a control lever coupled mechanically to a mobile electrical contact and an anti-bounce lever, mounted on the control lever and configured to be displaced to a deployed position to cooperate with an abutment to prevent the control lever from leaving its position.
    The switching device comprises a fixed bearing mounted around the control lever. The anti-bounce lever comprises a contact portion which is in contact against an edge of the bearing when the anti-bounce lever is in its rest position and which is displaced along the edge when the control lever rotates about the bearing. The bearing comprises, on the edge, a guiding portion in the form of a cam configured to push the anti-bounce lever to its deployed position.

    Abstract: An electrical switching device with separable contacts includes a switching apparatus including a fixed electrical contact and a mobile electrical contact that can be moved between a closing position and an opening position; a control lever mechanically coupled to the mobile electrical contact, the control lever being rotatable, about a first axis of rotation, between a first position and a second position; an anti-rebound lever arranged so as to move from a rest position to an opened-out position when the control lever reaches the second position. The anti-rebound lever engages a stop when it is in the opened-out position thereof and when the control lever is in the second position so as to prevent the control lever from leaving the second position.

    Abstract: A circuit interrupter includes a stationary contact and a moveable contact arm assembly having a moveable contact positioned thereon, the moveable contact configured to be moveable into and out of physical contact with the stationary contact. The circuit interrupter also includes an overcurrent tripping device coupled to the moveable contact arm assembly via a linkage assembly and configured to move the moveable contact out of physical contact with the stationary contact upon detection of an overcurrent situation. The moveable contact arm assembly is connected to the linkage assembly via at least two pivots positioned on the contact arm assembly, so as to cause a relative sliding action between the moveable and stationary contacts as the moveable and stationary contacts are moved into or out of contact with each other such that a wiping action is created in order to clean the moveable and stationary contacts.

    Abstract: A computer-implemented method for designing a pin joint having a bearing member and a pin member received within the bearing member is provided. The method includes receiving, via a Graphical User Interface (GUI), at least one input related to one or more pin joint configuration parameters. The method includes receiving, via the GUI, at least one input related to one or more pin member design parameters. The method includes receiving, via the GUI, at least one input related to one or more bearing member design parameters. The method includes calculating a set of design parameters of the pin joint based on the inputs related to the pin joint configuration parameters, the pin member design parameters, and the bearing member design parameters. The method includes generating an output design of the pin joint based on the comparison between the calculated set of design parameters with a set of predefined design parameters.
