| 主权项 | 1. An instant trip device of a circuit breaker, the instant trip device comprises: a magnet configured to generate a magnetic absorbing force with power applied thereto; a supporter disposed at a side opposite to the magnet; an armature is provided between the magnet and the supporter, and including a rotation center portion and a rotating part is disposed to be rotatable with respect to the rotation center portion; and an armature spring configured to apply an elastic force in a direction where the rotating part of the armature becomes farther away from the magnet, wherein, a groove of which one side is opened is formed at the supporter to support the rotation center portion of the armature, a boss is formed at the rotation center portion of the armature to be inserted into the groove, and the armature spring is an extension spring in which one end of the armature spring is supported by a first hanger included in the supporter, and the other end is supported by a second hanger included in the rotating part of the armature, wherein the opened one side of the groove is formed in a direction of the rotating part,wherein the supporter comprises a spring accommodating part which is formed at a side of the first hanger to pass through the supporter, so that there is no interference between the supporter and the armature spring. | ||
