A trip device comprising: a shut-down mechanism including a manipulation lever rotated between ON/OFF or trip positions and a first resilient member returning the manipulation lever to an ON position; a locking member latching the manipulation lever at an OFF position; a stator formed of a conductor such that current is induced to flow inwards; a mover rotated to contact or be separated from the stator upon generation of abnormal current; and a multi-articulate link member interlocking with the manipulation lever rotated to the OFF position to release the locking member when the mover and the stator are fused to each other upon generation of abnormal current; wherein the multi-articulate link member comprises: a first link connected at one longitudinal end thereof to the mover to interlock with the manipulation lever when the manipulation lever is rotated to the OFF position; a second link connected at one longitudinal end thereof to the other end of the first link to interlock with the first link; characterized in that the multi-articulate link further comprises a third link connected at one longitudinal end thereof to the other end of the second link to rotate about a rotational axis in conjunction with the second link; and in that the longitudinal ends of the first and second links connected to each other are bent upwards and are spread laterally in conjunction with the manipulation lever rotated to the OFF position when the stator and the mover are fused to each other, and the longitudinal end of the third link is rotated laterally when the second link is spread laterally. a shut-down mechanism including a manipulation lever rotated between ON/OFF or trip positions and a first resilient member returning the manipulation lever to an ON position; a locking member latching the manipulation lever at an OFF position; a stator formed of a conductor such that current is induced to flow inwards; a mover rotated to contact or be separated from the stator upon generation of abnormal current; and a multi-articulate link member interlocking with the manipulation lever rotated to the OFF position to release the locking member when the mover and the stator are fused to each other upon generation of abnormal current; wherein the multi-articulate link member comprises: a first link connected at one longitudinal end thereof to the mover to interlock with the manipulation lever when the manipulation lever is rotated to the OFF position; a second link connected at one longitudinal end thereof to the other end of the first link to interlock with the first link; characterized in that the multi-articulate link further comprises a third link connected at one longitudinal end thereof to the other end of the second link to rotate about a rotational axis in conjunction with the second link; and in that the longitudinal ends of the first and second links connected to each other are bent upwards and are spread laterally in conjunction with the manipulation lever rotated to the OFF position when the stator and the mover are fused to each other, and the longitudinal end of the third link is rotated laterally when the second link is spread laterally. a first link connected at one longitudinal end thereof to the mover to interlock with the manipulation lever when the manipulation lever is rotated to the OFF position; a second link connected at one longitudinal end thereof to the other end of the first link to interlock with the first link; characterized in that the multi-articulate link further comprises a third link connected at one longitudinal end thereof to the other end of the second link to rotate about a rotational axis in conjunction with the second link; and in that the longitudinal ends of the first and second links connected to each other are bent upwards and are spread laterally in conjunction with the manipulation lever rotated to the OFF position when the stator and the mover are fused to each other, and the longitudinal end of the third link is rotated laterally when the second link is spread laterally.
