A gas-insulated switchgear device comprising a first casing housing: at least a first terminal for input/output connection; a disconnector unit comprising at least a first fixed contact operatively coupled to said first terminal and a corresponding first movable contact which can be electrically connected/disconnected with said first fixed contact, during operation of the disconnector unit; a circuit breaker unit electrically connected to said disconnector unit and comprising at least a couple of interruption contacts which can be actuated, during operation of said circuit breaker unit, between a circuit breaker closed position where they are electrically coupled and a circuit breaker open position where they are electrically separated; actuating means for operating said disconnector unit and said circuit breaker unit; a second casing operatively coupled with said actuating means, which houses said interruption contacts and on the outer surface of which at least said first movable contact is mounted; characterized in that said second casing is pivotally mounted inside said first casing so as to rotate said first movable contact during operation of said disconnector unit, said couple of interruption contacts being operatively coupled to said actuating means so as to be kept electrically coupled in said circuit breaker closed position and substantially still relative to each other during rotation of said second casing.
