Abstract
The invention relates to a hybrid circuit-breaker which, for each pole, comprises a dielectric-gas interrupting chamber () which contains a first contact (A) and a moving second contact (B) that are disposed longitudinally to a first axis (AA') and in which the first contact (A) is connected to a first terminal (A) of the network, said interrupting chamber () being connected in series with a vacuum bottle () which contains a fixed contact (A) and a moving contact (B) that are disposed longitudinally to a second axis (BB′) and in which the fixed contact (A) is connected to a second terminal (B) of the network, actuating means acting via a single control () to move said moving contacts between respective open positions and respective closed positions. According to the invention, said actuating means comprise a re-closure arrangement for re-closing the moving contact (B) of the vacuum bottle, which re-closure arrangement enables said single control () to perform such re-closure before the moving contact (B) of said interrupting chamber reaches its open position.
