Abstract
Embodiments of a plug-in unit for an electrical enclosure are disclosed. The plug-in unit includes at least one stab configured to engage a bus, a stab shaft coupled with a base of the at least one stab, and a stab translation mechanism configured to translate the stab shaft such that the at least one stab translates from a retracted position to an extended position.
Claims20
A motor control system, comprising:
- an arc flash resistant enclosure;
- a plug-in unit disposed within the arc flash resistant enclosure;
- a stab assembly of the plug-in unit, the stab assembly comprising at least one stab;
- a stab translation mechanism of the plug-in unit, the stab translation mechanism configured to rotate the at least one stab about an axis of the at least one stab from a retracted position to an extended position;
- and
- an actuator configured to activate the stab translation mechanism from outside of the arc flash resistant enclosure, wherein the stab assembly comprises a shaft formed from a plurality of shaft segments configured to move horizontally relative to one another along an axis of the shaft.

- a plug-in unit disposed within the arc flash resistant enclosure;
- a stab assembly of the plug-in unit, the stab assembly comprising at least one stab;
- a stab translation mechanism of the plug-in unit, the stab translation mechanism configured to rotate the at least one stab about an axis of the at least one stab from a retracted position to an extended position;
- and
- an actuator configured to activate the stab translation mechanism from outside of the arc flash resistant enclosure, wherein the at least one stab comprises:
- a first plurality of stab leads, wherein each stab lead of the first plurality of stab leads is angled outward relative to a central axis of the at least one stab;
- and
- a second plurality of stab leads, wherein each stab lead of the second plurality of stab leads is angled outward relative to the central axis of the at least one stab, and wherein each stab lead of the second plurality of stab leads is angled downward relative to the central axis of the at least one stab when the at least one stab is in the extended position.
