  • Vacuum circuit interrupter grounding assembly
    Patent number: 7829814
    Abstract: A vacuum circuit interrupter having a pole unit structure and an operating mechanism structured to move the vacuum circuit interrupter contacts between a first, closed position, wherein a movable contact is coupled to, and in electrical communication with, a fixed contact, and a second, open position wherein the movable contact is spaced from, and not in electrical communication with, the fixed contact, as well as being structured to rotate a housing assembly rotatable portion between a first position, wherein a rotatable terminal is coupled to, and in electrical communication with, a line terminal, and a second position, wherein the rotatable terminal is coupled to, and in electrical communication with, a grounded terminal.
    Type: Grant
