Drive structure is provided for connection between an actuating assembly of a circuit breaker and linkage structure for opening and closing a movable electrical contact disposed in a volume of insulating material in a pole assembly. The drive structure includes a drive lever constructed and arranged to connect with the at least one actuating assembly. A drive shaft has first and second ends, with the first end being removably coupled to the drive lever so that rotation of the drive shaft rotates the drive lever. Seal structure is disposed between the drive lever and the actuating assembly such that the drive shaft can be removed from the drive lever without disrupting the volume of insulating material.
