Abstract (en)
[origin: EP1772883A1] A medium-voltage vacuum circuit breaker (100) comprising: - a plurality of interruption poles (1) each having two connection terminals, and a vacuum envelope (4) which contains a fixed contact and a mobile contact electrically coupled each to a corresponding terminal; - an operating mechanism (200) which has a front panel (7) and is suitable to supply actuating energy for moving the mobile contacts of the interruption poles between a circuit breaker closed position where they are each electrically coupled with the corresponding fixed contact and a circuit breaker open position where they are disengaged therefrom; - means (300) for transmitting the actuating energy from the operating mechanism to the mobile contacts; characterized in that each interruption pole comprises an insulating box delimiting an internal free volume which accommodates a corresponding vacuum envelope, said interruption poles being aligned each other and being arranged so as the respective mobile contacts are movable, during actuation, along a substantial vertical axis, with the vertical axes of the interruption poles lying in a common vertical plane which is substantially perpendicular to the front panel, and in that said transmission means are positioned on a side of the aligned interruption poles.
