The present invention relates to a pole unit of a circuit breaker which includes an insulation housing (1) which has a pole unit of circuit breaker of which fixated upper electrical contact point (7) is formed within the insulation housing (1) or is connected to an assembled electrical terminal (2), of which movable lower electrical contact point (4) is connected to an electrical contact point member (3) of the insulation housing (1) through a flexible conductor (6) for accommodating a vacuum interrupter (8) having a pair of corresponding electrical switching contact points (4, 7); a first end unit (11) to attach the flexible conductor (6) to the insulation housing (1); and a second end unit to attach the flexible conductor (6) to the movable lower electrical conductor (4). An inner screw (14) which is screw-engaged to an outer screw thread (15) arranged at the end of the movable lower electrical contact point (4) is provided in the second end unit (13) of the flexible conductor (6). |
