    • PURPOSE: A molded case circuit breaker is provided to obtain an assembly structure of a current-interrupting section equipped with a bridging rotary contact shoe. CONSTITUTION: A molded case circuit breaker comprises a switching mechanism, and a current-interrupting section connected to the switching mechanism, and including an insulated case(6), a pair of fixed contact shoes(7A) disposed inside the insulated case to face each other, each of the fixed contact shoes having a substantially linear conductor portion, a tip portion and a terminal portion, a rotary contact shoe disposed between the fixed contact shoes so that the fixed contact shoes and the rotary contact shoe form a Z-shape conducting path when the switching mechanism is on, and the rotary contact shoe is rotated to be separated from the fixed contact shoe by an electromagnetic counter force when an overcurrent flow through the Z-shape conducting path, and a contact shoe holder(9) linked to the switching mechanism and holding the rotary contact shoe.
    • 目的:提供一种塑壳断路器,以获得配有桥接旋转接触鞋的电流中断部分的组装结构。 构成:一个模制外壳断路器包括开关机构和连接到开关机构的电流中断部分,并且包括绝缘壳体(6),一对固定接触滑靴(7A),其设置在绝缘壳体内以面对每个 另一方面,每个固定接触鞋具有基本上线性的导体部分,尖端部分和端子部分,设置在固定接触鞋之间的旋转接触靴,使得固定接触靴和旋转接触靴形成Z形导电 当切换机构打开时,当流过Z形导电路径的过电流流动时,旋转接触靴被旋转以通过电磁反作用力与固定接触靴分离,并且接触靴保持器(9)连接到 切换机构并保持旋转接触鞋。
