  • Insertion/withdrawal mechanism for a circuit interrupter
    Patent number: 6563062
    Abstract: A circuit interrupter insertion/withdrawal mechanism including an interrupter moving device including a drive shaft operable by an external operating handle from outside of the interrupter compartment, a lever connected between the drive shaft and the interrupter for driving the interrupter between the disconnected and connected positions, and a motion translating device connected between the drive shaft and the interrupter for translating a rotary motion of the drive shaft into a linear motion of the interrupter between the disconnected and connected positions. The lever is rotatable between a disconnecting position corresponding to the disconnected position of the interrupter and a connecting position corresponding to the connected position of the interrupter, the disconnected and connected positions being at substantially diametrically opposed positions about a center of rotation of the lever.
