Abstract: The disclosure relates to a pole part of a circuit-breaker arrangement having an insulation housing for accommodating a vacuum interrupter containing a pair of corresponding electrical switching contacts, wherein a fixed upper electrical contact is connected to an upper electrical terminal molded or assembled in the insulation housing and a movable lower electrical contact is connected to the insulating housing by a support plate of the insulation housing via a flexible conductor that includes a first end for attaching the flexible conductor to the lower electrical terminal and a second end for attaching the flexible conductor to the movable lower electrical contact. The second end of the flexible conductor is provided with an inside thread which is screwed to an outside thread arranged on the distal end of the movable lower electrical contact.

Abstract: An exemplary assembled pole part includes two pole part frames made of insulating material, between which a vacuum interrupter is mounted. The vacuum interrupter includes a fixed contact and a moving contact. The frame includes a first support to affix the vacuum interrupter at the moving contact side, and a second support to affix the vacuum interrupter to the fixed contact side at an opposite end of the frame. In order to apply common pole part frames for different vacuum interrupter sizes, in order to alleviate the manufacture of such pole parts, at least two fixation points are arranged pairwise in parallel along different distances along the long axis of the frame. The first support at the moving contact side maintains a specified fixation position, so the frame is configured for use with at least one other vacuum interrupter of a different length.

Abstract translation: 示例性的组装极部分包括由绝缘材料制成的两个极部分框架，在其之间安装有真空断路器。 真空断路器包括固定触点和移动触点。 该框架包括用于将真空断路器固定在移动接触侧的第一支撑件和第二支撑件，用于将真空断路器固定在框架的相对端处的固定触点侧。 为了应用不同真空断路器尺寸的共同极部件框架，为了减轻这种极部件的制造，至少两个固定点沿着框架的长轴沿着不同的距离成对平行设置。 可移动接触侧的第一支撑件保持指定的固定位置，因此该框架配置为与不同长度的至少一个其他真空断路器一起使用。
