On an insulating baseboard with a central opening there are located contacts. There are also auxiliary contacts intended for connecting local control circuits of the device. A rotational electromechanical drive is provided to rotate a contactor, and an electromagnetic drive is adapted to reciprocate said contactor for operating contacts. The electromagnet drive has an electromagnet for closing contacts and a plurality of electromagnets for opening contacts. The number of the electromagnets corresponds to the number of the contact fixing devices. The armature of each electromagnet is connected with one of the contact fixing devices.
