1. A trip device for a circuit breaker, comprising:
a crossbar rotatably installed to perform the trigger function; and a bimetal that is curved upon the occurrence of an abnormal current and presses and rotates the crossbar by means of a gap adjustment member, wherein the crossbar is movable in the direction of a rotating shaft of the crossbar, the gap adjustment member is attached to and detached from either the crossbar or the bimetal at varying angles so that a contact surface of the gap adjustment member is parallel or at an angle to the direction of movement of the crossbar, and if the contact surface of the gap adjustment member is at an angle to the direction of movement of the crossbar, the gap between the contact surfaces is adjusted depending on the position of the crossbar on the rotating shaft, and if the contact surface of the gap adjustment member is parallel to the direction of movement of the crossbar, the gap between the contact surfaces is kept constant regardless of the position of the crossbar on the rotating shaft. |
