A compressed-gas-insulated switching deviceincludes a grounded encapsulating housing formed of an electrically conductive material and an electrically insulated phase conductor disposed inside the encapsulating housing. First and second flanges are disposed on the grounded encapsulating housing. Insulating housings respectively containing a switch disconnector and an interrupter unit of a power circuit breaker, are connected to the flanges. The insulating housings containing the switch disconnector and the interrupter unit are interchangeable.
