Abstract (en)

A switching apparatus for medium voltage electric systems, said switching apparatus comprising one or more electric poles and, for each electric pole:- a first pole terminal, a second pole terminal and a ground terminal, said first pole terminal being electrically couplable with a first conductor of an electric line, said second pole terminal being electrically couplable to a second conductor of said electric line and said ground terminal being electrically couplable to a grounding conductor;- a fixed contact assembly including a plurality of fixed contact members spaced one from another;- a movable contact assembly rotatable about a rotation axis between a first end-of-run position (P<sub>A</sub>), which corresponds to a closed state of said switching apparatus, and a second end-of-run position (Pc), which corresponds to a earthed state of said switching apparatus, said movable contact assembly passing through an intermediate position (P<sub>B</sub>), which corresponds to an open state of said switching apparatus, when moving between said first and second end-of-run positions.The movable contact assembly is arranged so that, when the switching apparatus is in an open state, the electric contacts within a vacuum chamber of the movable contact assembly are mutually coupled.
