Abstract:
1. A drive structure for connection between an actuating assembly of a circuit breaker and a linkage structure for opening and closing a movable electrical contact disposed in a volume of insulating material in a pole assembly, the drive structure comprising: a drive lever constructed and arranged to connect with the actuating assembly, a drive shaft having 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, a linkage lever coupled to the second end of the drive shaft, at least one connection rod, as part of the linkage structure, coupled with the linkage lever so that the connection rod is generally transverse with respect to the drive shaft, and a seal structure 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.
