  • External operating handle mechanism for mold cased circuit breaker
    Patent number: 7361857
    Abstract: An external operating handle mechanism for a mold cased circuit breaker comprising: an external operating handle; a pinion gear coupled to the external operating handle to be rotatable in response to a rotation of the external operating handle; a movable member provided with a rack gear portion coupled to the pinion gear to be linearly movable according to the rotation of the pinion gear, and provided with a handle connecting portion connected to the handle of the mold cased circuit breaker to linearly move the handle of the mold cased circuit breaker; and a guide member for guiding the movable member to linearly move, by which it is easy to control a stroke required for a displacement of the handle of the mold cased circuit breaker and the displacement of the external operating handle according to the stroke, and it is possible to accurately and efficiently transfer power upon performing a reset operation.
