    • PROBLEM TO BE SOLVED: To provide a rotation pin correction device of a quadrupole circuit breaker which corrects deformation generated at a portion of the rotation pins between a monopolar breaker unit most separated from a switching mechanism and an adjoining monopolar breaker unit.
      SOLUTION: The rotation pin correction device of a quadrupole circuit breaker includes a correction plate 4 which has a pair of rotation pin through-hole parts 4a, 4a' which are installed at a portion of a pair of rotation pins 2a, 2b located between the monopolar breaker unit 3d most separated from the switching mechanism 1 and the monopolar breaker unit 3c adjoining this and permit penetration of the pair of rotation pins 2a, 2b respectively and a pair of adjusting projection parts 4b, 4b' which are extended in the penetration direction of the rotation pins 2a, 2b from the upper part or lower part of the rotation pin through-hole parts 4a, 4a' and determine the height of the penetration permitting hole of the rotation pins 2a, 2b together with the rotation pin through-hole parts 4a, 4a'.
