    • An electric pole for a low-voltage power circuit breaker, comprising an insulating enclosure (20, 30) that has a lower wall, an upper wall, two side walls, a rear wall and a front wall, at least one arc chute, at least one fixed contact (8) and at least one moving contact (9) that can be mutually coupled/uncoupled, and a first electric terminal (10) and a second electric terminal (11) that are functionally associated with the fixed contact and the moving contact and allow electrical connection of the pole in input and in output, its particularity consisting of the fact that the insulating enclosure comprises a first half-shell (20) and a second half-shell (30) which are mutually coupled along corresponding coupling surfaces and form a self-supporting structure, the first and second half-shells being shaped so as to form at least one compartment (12) that is suitable to accommodate the fixed contact and the moving contact and the arc chute, and second (13) and third containment volumes (14), which are arranged on mutually opposite sides with respect to the compartment and are suitable to accommodate respectively the first and second electric terminals.
    • 1.一种用于低压电力断路器的电极,包括具有下壁,上壁,两个侧壁,后壁和前壁的绝缘外壳(20,30),至少一个弧形槽 至少一个固定触点(8)和至少一个能够相互耦合/不连接的移动触点(9),以及与固定触点和功能上相关联的第一电端子(10)和第二电端子(11) 移动接触并且允许极在输入和输出中的电连接,其特性包括以下事实:绝缘外壳包括第一半壳(20)和第二半壳(30),第一半壳(20)和第二半壳(30) 表面并形成自支撑结构,第一和第二半壳被成形为形成适于容纳固定触点和移动触点和电弧槽的至少一个隔室(12),第二(13) )和第三个包容卷 (14),其相对于所述隔间布置在相互相对的两侧,并且适于分别容纳所述第一和第二电端子。
