Next, the operation will be described. Only one of the poles, for example, the unipolar circuit or the breaker (32), has an overcurrent and the operating plate (9)
4 rotates counterclockwise in FIG. 4 and the trip rod (12) falls, that is, when the state shown in FIG. 4 is changed to the state shown in FIG. 5, the drive pin of the trip rod (12). (14) engages with the engaging portion (34d) of the connector (34), and the connector (34) rotates counterclockwise in FIG. 4 about the shaft portion (34b).
When the connector (34) rotates in this manner, the notch (35) is formed.
As a result, the actuator (36a) is actuated to the state shown in FIG. 4 to FIG. 5 and the alarm switch (36) is actuated, and a signal indicating that an overcurrent has flown to the circuit or the breaker is transmitted. Further, as the connector (34) rotates, the actuating plate (9) is pushed by the engaging portion (34e) of the other unipolar circuit or breaker (33) in which no overcurrent flows, and the tripping rod is also released. (12) drops. That is, the opening and closing operations are simultaneously performed in both poles.
