A gas-insulated switchgear assembly () or component of a gas-insulated switchgear assembly is proposed which has an outdoor bushing () through which at least one high voltage-carrying conductor () is passed. A surge arrester () is arranged essentially parallel to the outdoor bushing () and is connected to the high voltage-carrying conductor () and/or to the top part of the outdoor bushing () via a high voltage-side connection piece () and to the foot part of the outdoor bushing () and/or to the housing of the gas-insulated switchgear assembly or the component of the gas-insulated switchgear assembly via a housing-side connection piece ().

A circuit breaker and/or earthing switch are disclosed wherein a rotatable spindle nut, which is mounted in a spindle housing, displaces a spindle in a translatory manner, thus displacing contact elements of the switching device. The spindle actuates a contact pin that is configured in a contact carrier by a connection yoke that is common to all phases or poles and an isolating bar for each phase or pole.
