Abstract
A circuit breaker has within a casing filled with a dielectric gas, especially SF.sub.6, a first arcing contact electrically connected to a first terminal, and a second arcing contact electrically connected to a second terminal. The second arcing contact is movable within a fixed cylinder. A piston is movable within said fixed cylinder. The fixed cylinder and the piston form a compression chamber. The first arcing contact and the piston are movable relative to each other. An actuating mechanism actuates the first arcing contact in a direction opposite to that of displacement of the second contact, and actuates the piston in a direction opposite to that of the displacement of the second contact.
