Abstract

A circuit breaker movement (10) structure is provided for use with a circuit breaker (12) to move the circuit breaker be connected with or be disconnected from a circuit breaker connecting apparatus (14). The movement structure comprises a draw bracket assembly (68) and (70) constructed and arranged to be mounted to the circuit breaker connecting apparatus. A guide assembly (16) is constructed and arranged to be mounted to the circuit breaker (12). The draw bracket assembly includes drive structure constructed and arranged to be actuated to engage the guide assembly and cause the circuit breaker to move with respect to the circuit breaker connecting apparatus. The draw bracket assembly includes a movable structure (108) coupled thereto so as to be moved in a linear manner between first, second, and third positions while maintaining the movable structure in one of the positions. The movable structure (108) is constructed and arranged such that: In the first position, the movable structure (108) permits the circuit breaker (12) to be initially connected with or be disconnected from the circuit breaker connecting apparatus (14), and prevents actuation of the drive structure (94). In the second position, the movable structure (108) prevents the circuit breaker (12) to be connected with or be disconnected from the circuit breaker connecting apparatus (14), and prevents actuation of the drive structure (94). In the third position, the moveable structure (108) permits the circuit breaker (12) to be connected with or be disconnected from the circuit breaker connecting apparatus (14) but prevents the circuit breaker from being completely disengaged with respect to the draw bracket assembly (68) and (70), and the movable structure (108) permits actuation of the drive structure (94).
