A method for operating a drive of a vacuum interrupter in opening mode includes: dividing an opening movement of at least one movable contact into serial phases, an opening phase, and an isolating phase, driven in at least two different velocities. In the opening phase a velocity of the opening movement is lower than in the isolating phase.
