摘要： A circuit breaker arrangement is disclosed. It comprises a cart (1) on which slides a circuit breaker. A lead screw (14) drives the circuit breaker along a linear path by moving a drive block (15), an upper protuberance (211) of which engages the circuit breaker. The arrangement provides for an automatic uncoupling of the circuit breaker at an end position of the drive block (15), where a handle inserted into a hole (24) may turn an end of the lead screw and rock the drive block with a meshing mechanism (43) so that the protuberance (211) escapes the circuit breaker. It is therefore very easy to mount, dismount or replace the circuit breaker. A similar advantage based on unlatching an interlock may be obtained for dismounting the electrical motor (12) that normally drives the lead screw (14). The invention can well take place in the medium voltage industry.

摘要： A truck (12′) for mounting a circuit breaker (13) in a switchgear frame (14′) includes wheels (16), a racking screw (20), a nut (22) threaded with the racking screw. The nut floats linearly with respect to the truck. A spring (23) is provided between a portion of the truck and the nut such that during movement of the truck into the frame, rotation of the racking screw causes linear movement of the nut, with the nut pushing against the spring, with the spring pushing the truck to move the truck linearly. Locking structure is coupled with the such that when the truck is stopped and the racking screw continues to rotate, the nut will move to compress the spring, causing the locking structure to move from an unlocked position, disengaged with the frame, to a locked position, engaged with the frame.
