PROBLEM TO BE SOLVED: To increase workability even without branch conductors for a bus and with the reduction in a space of a bus chamber and lessen the number of bushings and eliminate the necessity of an insulator to support the bus. SOLUTION: An S-phase bus bushing 20a in a bus chamber 7 has a conductor 22 which is molded in an electric insulating material-made molded body 21 and which is branched from the bus chamber 7 side into two breaker chamber sides 8a, 8b. The conductor 22 is jutted outside the molded body 21 at the bus chamber 7 side to form a bus terminal 22a to which a bus 14s can be connected. Meanwhile, the conductor 22 is jutted outside the molded body 21 at the breaker chambers 8a, 8b side to form disconnecting contacts 22a, 22b. Flanges 21f are formed in the molded body 21 for installing the molded body 21 on a partition wall 9. In order to branch the conductor 22 into the bus terminal 22s and the disconnecting contacts 22a, 22b, an intermediate conductor 22m is used. The bus terminal 22s and the disconnecting contacts 22a, 22b are connected to the intermediate conductor 22m by brazing. |
