Claims13
A method for providing a circuit disconnect apparatus, the method comprising:
- providing a movable blade plate mounted to a first conductor of the circuit, wherein the movable blade plate includes a pin mounted to a portion of the movable blade plate;
- providing a pivot bar mounted in a stationary position to a second conductor of the circuit;
- providing a C-shaped plate mounted to the fixed pivot bar, wherein the C-shaped plate rotates about an axis with respect to the pivot bar, the C-shaped plate having an elongated portion connected to a hook portion with an opening between the elongated portion and the hook portion;
- when the apparatus is in a closed position, the movable blade plate moves adjacent the C-shaped plate, wherein the pin moves within the opening of the C-shaped plate, and the pin is in contact with the C-shaped plate;
- when a disconnect operation is initiated for the apparatus, the movable blade plate is retracted away from the C-shaped plate, wherein the pin moves along the elongated portion until the pin disengages contact with the C-shaped plate and is no longer within the opening of the C-shaped plate;
- and
- when an unexpected disconnect event occurs, and the apparatus is initially in a closed position, the movable pin is retained within the opening of the C-shaped plate and the pin remains in contact with either the elongated portion or the hook portion of the C-shaped plate.

A circuit disconnect apparatus comprising:
- a movable blade plate mounted to a first conductor of a circuit, wherein the movable blade plate includes an external surface, the moveable blade plate including one or more stoppers;
- a connecting device mounted to a second conductor of the circuit, the connecting device including a hook;
- a mechanism operable to provide contact between the movable blade plate and the connecting device when the apparatus is in a closed position;
- wherein when a disconnect operation is initiated for the apparatus, the movable blade plate is retracted away from the connecting device, wherein the mechanism permits the movable blade plate to retract away from the connecting device until there is no contact between the movable blade plate and the connecting device;
- and
- wherein when an unexpected disconnect event occurs, and the apparatus is in a closed position, the mechanism inhibits the movable blade plate from retracting away from the connecting device and maintains contact between the movable blade plate and the connecting device.

A method for using a circuit disconnect apparatus, the method comprising:
- manipulating a movable blade plate mounted to a first conductor of a circuit, wherein the movable blade plate includes a pin mounted to a portion of the movable blade plate, towards a pivot bar mounted in a stationary position to a second conductor of the circuit, wherein a C-shaped plate is mounted to the pivot bar;
- as the movable blade moves towards the pivot bar, rotating the C-shaped plate about an axis with respect to the pivot bar, the C-shaped plate including an elongated portion connected to a hook portion with an opening between the elongated portion and the hook portion;
- when the apparatus is in a closed position, maintaining contact between the movable blade plate and the C-shape plate, wherein the pin moves within the opening of the C-shaped plate, and the pin is in contact with the C-shaped plate;
- when an intended disconnect operation is initiated for the apparatus, retracting the movable blade plate away from the C-shaped plate, wherein the pin moves along the elongated portion until the pin disengages contact with the C-shaped plate and is no longer within the opening of the C-shaped plate;
- and
- when an unexpected disconnect event occurs and the apparatus is in the closed position, retaining the pin within the opening of the C-shaped plate and the pin remains in contact with either the elongated portion or the hook portion of the C-shaped plate.
