    • The invention relates to a low-voltage circuit breaker with a retrofitted power-driven lift, whereby the output shaft thereof can be coupled to the charging shaft of the spring energy store of the low-voltage circuit breaker and said charging shaft is mounted in a bearing block. Centering elements (9) are provided on one flange of the bearing block (11) of the charging shaft (12) of the spring energy store and engage with counter elements (10) on the output side of the gear of the power-driven elevator (5) in such a way that the lift can extend axially with only a limited amount of travel in the direction of the charging shaft (12). In order to arrest the power-driven lift (5) in a pivoting direction, a fixing element is provided at a point located at a certain distance from the centre, in addition to means enabling the power-driven lift (5) to be fixed in an axial position in the centering elements (9) of the flange of the bearing block (11) of the charging shaft (12) of the lift of the spring and in the coupling (8) of the charging shaft (12).
    • 本发明涉及一种具有可改装马达复位机构,其输出轴连接于安装在所述低压断路器的弹簧蓄能器的轴承座夹紧轴的轴上的低压断路器。 根据设置在电机复位机构(5)的齿轮箱输出的本发明的弹簧蓄压器定心元件(9),用于与反作用元件(10)接合的夹持轴(12)的轴承座(11)的一个凸缘,这样,在这些对中元件(9)与所述马达提取 在夹紧轴(12)的方向上小距离轴向可插入。 以锁定在枢转方向上的马达复位机构(5),固定件被设置在一个安装在由在一定的距离点在定心和用于轴向固定电动机复位机构(5)在所述定心元件(9)的轴承座的凸缘(11 )夹紧轴(12)的弹簧的夹持轴(12)与提升机(在离合器8)的存在。
