Assembly work of invention description (19) , And the introduction of automated lines for assembly automation devices has become feasible. Therefore, in addition to greatly improving productivity and reducing manufacturing costs, in particular, the overcurrent trip device of each pole is connected to the trip lever and latch of the trip device via a configuration. The trip unit assembly unit, which is assembled in a common unit case, is compared with the structure in which each part is separately assembled in the circuit breaker case. In addition to reducing the number of work and improving the operating efficiency, Ensuring high assembly accuracy makes the tripping characteristics of circuit breakers safe (2). According to the unit housing of the trip unit assembly unit, the main circuit conductor is arranged on the upper side, and it is suitable for leakage circuit breakers. The ZCT for leakage detection, the structure of the patent application scope item 2 of the printed circuit board, can also easily and flexibly correspond to the circuit breaker of the leakage circuit breaker. (3) Also, as a jumper The positioning and fixing means of the disassembly device assembly unit are in accordance with the structure of the third to the fifth of the patent application scope. For the case (mold container of the circuit breaker), the unit case will not be subjected to the load caused by the tripping action. It may cause deviation from a predetermined assembly position due to the influence of the relative positional relationship between the latch seat assembled in the unit case and the latch of the contact switch mechanism portion facing the latch seat. The stable tripping action can be implemented to improve the reliability of the finished product.
