L'invention concerne un dispositif de commutation plein air (1) et un procédé servant à commuter des tensions élevées de plusieurs phases (20, 21, 22). Le dispositif de commutation plein air comprend au moins deux unités de coupure (2, 3, 4), lesquelles sont associées à respectivement une phase (20, 21, 22) différente et sont disposées sur un support (8) commun. Selon le procédé selon l'invention servant à commuter un dispositif de commutation plein air (1) décrite ci-avant, toutes les unités de coupure (2, 3, 4) sont comprises par des bras sur le support (8) et/ou sont commutées par exemple simultanément par l'intermédiaire d'un entraînement (14) commun et/ou d'éléments d'une chaîne (16) cinématique, en particulier avec un branchement, pouvant être prédéfini différemment et/ou pouvant être régulé ou commandé, de bras différents.
