<p>A movable contactor (D) of a circuit breaker, comprising: a cage (10) for angularly rotating with one side as a axis; a plurality of fingers (20) disposed at the cage, including a path body portion (21) having a predetermined thickness and having one end of an inclined plane, a wire connecting portion (22) extending from one end of the path body portion with steps so as to have a certain area and having one horizontal plane (2), and an arc discharge portion (23) extending from another end of the path body portion with a predetermined length so as to induce the discharge of the arc; and contact terminals (30) each coupled to each of the fingers and for contacting or being separated from a fixed contactor (C) according to the angular-rotation of the cage. Accordingly, the fabrication process for fingers (20) is facilitated and the material cost necessary to fabricate the fingers can be reduced, thereby reducing the fabrication cost.</p> |
