When an overcurrent flows in the ON state shown in FIG. 9 and FIG. 10, the automatic trip device (4) is activated to operate the trip bar latch (26) and the latch lever (27) to move the latch (2).
4) Rotates and the cradle (20a) disengages from the latch (24) and flips up in the direction of the arrow (31) in Fig. 10, so that the operation of this opening / closing mechanism (20) lifts the contact arm (10). The movable contact (6) opens and trips. Also at this time, the rotation of the first contact arm (10a) is caused by the crossbar (13) to the first position of the adjacent pole (1B) in FIG.
Transmitted to the contact arm (10a) of the adjacent pole (1B)
The contact arm (10) of the
The movable contact (6) opens and trips as shown. When the cradle (20a) disengages from the latch (24) and jumps up in the direction of the arrow (31), the lever (29) is rotated in the direction of the arrow (35) in FIG. 10 by the force of the twist spring (30), The trip state shown in FIG. 12 is obtained. The rotation of this lever (29) is transmitted to the actuator (33) via the support shaft (25), and the actuator (33) rotates in the direction of the arrow (36) in Fig. 11 to establish the trip state in Fig. 13. Alarm switch (32) switches. In other words, an alarm will be issued to notify the trip or break of the broken wire.

It should be noted that when a large current such as a short-circuit current flows in the form shown in the figure or when the circuit breaker moves, the electromagnetic force generated between the fixed conductor (2) and the mover (7) causes movement to the fixed conductor (2). The child (7) repels and separates. At this time, although the first contact arm (10a) has a delay in the operation of the opening / closing mechanism (20) due to the relay time by the automatic trip device (4),
The second contact arm (10b) overcomes the urging force of the pulling spring (17), removes the second pin (16) from the recess (14a), and moves the guide pin (14) to move the support shaft (12). ) As a fulcrum, and the second pin (16) collides with the end (14b) of the guide hole (14) and stops. This repulsive movement is faster than the operation of the opening / closing mechanism (20) in which the mover (7) is connected via the contact arm (10), and thereby enhances the current limiting effect.
