  • a conventional circuit breaker disclosed in Patent Document 1 has a so-called “single-pole double-throw”" operation mechanism in which two pairs of contacts consisting of a fixed contact and a movable contact are provided. Because this conventional circuit breaker is configured to be single-pole double-throw, the arc voltage thereof becomes twice as large as the arc voltage of a single-pole single-throw circuit breaker; in particular, the single-pole double-throw operation mechanism is suitable for a circuit breaker having a large breaking capacity.
  • This conventional circuit breaker realizes the single-pole double-throw configuration in such a way that respective movable contacts are provided at both ends of apivotable movable contact carrier and in such a way that a power-source-side contact pedestal and a load-side contact pedestal having respective fixed contacts that each make contact with or part from the respective corresponding movable contacts are arranged in point symmetry with respect to the pivotal center of the movable contact carrier.

  • the movable contactor 9 supported by the rotor 13 pivots counterclockwise; then, as illustrated in FIG. 2 , the movable contactor 9 comes into the so-called Trip mode, while making the power-source-side movable contact 8 separated from the power-source-side fixed contact 7 and making the load-side movable contact 10 separated from the load-side fixed contact 11.
  • the operation of the link rotor 24 that is driven by the toggle link mechanism consisting of the upper link 20, the lower link 21, and the main spring 23 is transferred to the rotor 13 through the roller 27 and the coupling shaft 25, so that the ON operation, the OFF operation, and the Trip operation of the circuit breaker are realized. Because the force transfer between the link rotor 24 and the rotor 13 is performed by means of rolling contact between the roller 27 and the inner wall of the elongate hole 24b of the link rotor 24, the friction coefficient becomes extremely small, whereby the transfer efficiency is raised.
