The distribution main body 110 is coupled to the main circuit breaker terminal 140 and the plurality of sub-breaker terminals 150. Distribution body 110 of one body according to the present invention is formed stepped stepwise. For example, as shown in FIG. 2, the distribution main body 110 may be formed in three staircase structures of the upper end 111, the middle end 113, and the lower end 115.

At this time, the main circuit breaker terminal 140 is coupled to one side of the upper end 111, and the plurality of sub circuit breaker terminals 150 are provided at the other side, the middle end 113, and the lower end 115 of the upper end 111. ) Are divided and combined.

The upper end 111 has a main circuit breaker terminal coupling hole 111a through which the main circuit breaker terminal 140 is coupled, and a first sub circuit breaker terminal coupling hole 111b is recessed on one side thereof. The second sub-breaker terminal coupling hole 113a is recessed in the middle end 113 and the lower end 115, and the third sub-breaker terminal coupling hole 115a is penetrated.

On the inner wall surface of each terminal coupling hole (111a, 111b, 113a, 115a) is formed a screw surface to which the fixing bolt 121 is screwed.

When the upper end 111, the intermediate end 113 and the lower end 115 are stepped to form a step, a plurality of arranged in the upper end 111, the intermediate end 113 and the lower end 115 Since the positions of the sub breaker terminals 150 are not overlapped with each other, the plurality of sub breaker terminals 150 may be identified at a time in an operator's eyes when viewed from the front. Accordingly, information such as stickers and numbering tubes attached to the plurality of sub-breaker terminals 150 can be easily recognized.

In addition, since the multi-stage structure is taken according to the number of the plurality of sub-breaker terminals 150, a larger number of sub-breaker terminals 150 may be coupled to the distribution main body 110 of the same size.
