Abstract: A movable contactor of a circuit breaker, comprising: a cage for angularly rotating with one side as a axis; a plurality of fingers disposed at the cage, including a path body portion having a predetermined thickness and having one end of an inclined plane, a wire connecting portion extending from one end of the path body portion with steps so as to have a certain area and having one horizontal plane, and an arc discharge portion extending from another end of the path body portion with a predetermined length so as to induce the discharge of the arc; and terminals each coupled to each of the fingers and for contacting or being separated from a fixed contactor according to the angular-rotation of the cage. Accordingly, the fabrication process for fingers is facilitated and the material cost necessary to fabricate the fingers can be reduced, thereby reducing the fabrication cost.

Abstract: Disclosed is a tulip contacting device for a vacuum circuit breaker employed to quickly break off an electric power system, in which contact fingers are bidirectionally rotatable in a state of being restricted at an outer diameter portion of a mover holder, such that the flexibility of the contact fingers can be increased, whereby it is possible, upon connecting the vacuum circuit breaker to a case, to flexibly deal with the variation of axial angles of terminals inserted in both sides of the tulip contacting device, and also springs may be coupled to the contact fingers, respectively, so as to effectively prevent separation and overall destroy of the contact fingers from the mover holder during installation.
