Arrangement for providing various circuit protection device

Abstract

An arrangement for efficiently assembling and providing a plurality of circuit protection device configurations by use of major components that are common to the configurations and that are adapted for interconnection and functioning with each other; some of the major components providing different or multiple functions in the various configurations. The various configurations satisfy the application requirements and customer needs with regard to voltage rating, efficient space usage, station layouts, and the provision of disconnect mechanisms. The configurations include various orientations of interrupting units and the provision of various types of disconnect mechanisms. The major components include an operator, an interrupting unit, an insulating support column, and a base drive. The operator provides a first drive output and a second drive output. The insulating support column is capable of being rotated to provide a rotary drive output for disconnect mechanisms. The insulating support column also internally carries an operating member. The operating member is driven to operate the interrupting unit. The base drive is connected to receive the first drive output of the operator and in turn to provide a driving output to the operating member. The second drive output is connected through appropriate linkage to rotate the insulating support column.
