PROBLEM TO BE SOLVED: To provide a power breaker equipped with an erroneous input preventive mechanism for easily carrying out correction of stroke error.SOLUTION: A length adjustment mechanism (60) is installed at a coupling member (55) to couple between a breaker spring operating part 23 and an input operation mechanism 26 of the erroneous input preventive mechanism 27. Furthermore, the coupling member (55) is set on the outermost side of a cabinet 17. As described above, since the length adjustment mechanism (60) is installed at the coupling member (55) of the erroneous input preventive mechanism 27, an operator corrects the stroke error easily and the erroneous input preventive mechanism 27 is functioned normally. Furthermore, since the coupling member (55) is installed at the outermost side of the cabinet 17, correction operation is carried out easily without a great amount of labor and time. |
