Abstract
A gas-insulated circuit breaker is disclosed that includes a housing defining a gas volume for a dielectric gas; a nominal contact system and an interruption contact system with a pin and a tulip that they are electrically connectable to and disconnectable from one another along an axis. The circuit breaker includes a guiding assembly including a guide sleeve and a guiding member that is coupled to the pin; and a gas damping assembly configured to damp a breaking movement of the pin by compressing the dielectric gas in an absorber volume. A movable absorption element and the absorber volume are arranged radially inward of the guide sleeve.
