ABSTRACT:
A lever pivotally mounted on a forward brace of a removable control unit abuts a pin on the cabinet for limiting direct insertion of the unit to a depth insufficient to effect electrical engagement of plug-in connectors of the unit with bus bars in a motor control cabinet, such engagement requiring subsequent pivotal movement of the lever which automatically latches the unit in the cabinet. A compound movement of the lever is required to release the latch and separate the plug-in connectors from the bus bar. A detent structure maintains the lever in a first position for inserting the control unit into the cabinet and padlocking provisions are provided to insure the lever remain in that position when desired, thereby blocking full insertion of the control unit into the cabinet. Interlocking means between the operator assembly for the control unit and the lever prevent pivotal movement of the lever and consequently engagement or separation of the plug-in connectors and bus bars when the control apparatus is in its ON condition.
