<P>PROBLEM TO BE SOLVED: To provide a racking mechanism of a drawout circuit breaker for fixing the drawout circuit breaker in an enclosure. <P>SOLUTION: At least one racking cam 62 is movably arranged in an enclosure, and is in operable communication with an input link 54. The racking cam 62 has at least one cam groove which receives part of a circuit breaker. By moving a cross shaft 42 around a central line of the cross shaft, at least one racking cam 62 is moved from an open position toward a closed position in a state, where part of the circuit breaker is located in at least one cam groove, and thereby the circuit breaker can be fixed inside the enclosure. At this time, at least one racking cam 62 is set to the closed position. <P>COPYRIGHT: (C)2010,JPO&INPIT |
