Abstract
An apparatus includes a circuit interrupting device installed in a cabinet. The circuit interrupting device has an actuator configured for rotation about a switching axis to switch the device between ON and OFF conditions. The apparatus further includes a front access hub supported for rotation about an axis orthogonal to the switching axis. A handle is coupled to the front access hub to rotate the front access hub about the orthogonal axis. A mechanism interconnects the front access hub with the actuator to rotate the actuator in response to rotation of the front access hub.
Claims15
An apparatus comprising:
- a cabinet;
- a circuit interrupting device installed in the cabinet, the circuit interrupting device having an actuator configured for rotation about a switching axis to switch the circuit interrupting device between ON and OFF conditions;
- a front access hub supported for rotation about an axis orthogonal to the switching axis;
- a handle coupled to the front access hub to rotate the front access hub about the orthogonal axis;
- a first link coupled to the front access hub to project radially from the orthogonal axis, and to move pivotally about the orthogonal axis upon rotation of the front access hub;
- a second link coupled to the actuator to project radially from the actuator, and to rotate the actuator about the switching axis upon movement of the second link pivotally about the switching axis;
- and
- a third link coupled between the first and second links to transmit pivotal movement between the first and second links;
- wherein the third link is coupled between the first and second links to move in opposite directions between the first and second links upon movement of the first and second links pivotally about the orthogonal axis and the switching axis;
- and
- the third link has a first elongated slot with opposite ends, the second link projects through the first elongated slot, and the opposite ends of the first elongated slot are movable against the second link to move the second link pivotally about the switching axis.
