Claims (1)
引き外し機構および熱動引外し機構が支持され、
かつ上記開閉機構に操作ハンドルが連結された回
路しや断器において、上記U字形固定枠の開放側
のいずれか一方の側壁に、対向する他方の側壁に
向けてのびる腕を設け、この腕にストツパ段部を
形成するとともに、このストツパ段部の先端に形
成された係止部が他方の側壁に形成した係合孔に
嵌合され、上記両側壁がU字形の屈曲基部から開
放端まで一様な寸法で対向して互いに連結されて
いることを特徴とする回路しや断器。 A movable contact device, an opening/closing mechanism, an electromagnetic tripping mechanism, and a thermal tripping mechanism are supported by a U-shaped fixed frame.
And in the circuit breaker in which the operating handle is connected to the opening/closing mechanism, an arm is provided on one of the open side walls of the U-shaped fixed frame and extends toward the other opposing side wall, and the arm is provided with an arm extending toward the opposite side wall. A stopper stepped portion is formed, and a locking portion formed at the tip of the stopper stepped portion is fitted into an engagement hole formed in the other side wall, so that the both side walls are aligned from the U-shaped bent base to the open end. Circuit breakers and circuit breakers are characterized in that they are connected to each other facing each other with various dimensions.
