Considering that the maximum diameter of the lower conductor 15 is at the same level as the flange of the current transformer 11, the instrument transformer 7 must be arranged in consideration of this flange diameter, and the main bus line 1° This results in an increase in the axial length of 2. Therefore, arranging the instrument transformer 7 between the upper electric circuit 14 and the lower electric circuit 150 shortens the axial length of the ¥ bus bar.

Because the transformer is arranged, each device can be configured in a single-bus system with a short main bus axial length. Furthermore, since the instrument transformer is horizontal and located at a height between the upper and lower circuits of the circuit breaker, each device can be placed close to each other and the main bus length can be shortened.
