Zusammenfassung:An electric circuit switchgear includes main contacts circumferentially arranged on a fixed panel and auxiliary contacts. The switchgear also includes a rotary electromechanical drive connected with a driving shaft and enabling the latter to be turned through a pre-set angle. The driving shaft is rotated together with an actuating element of an electromagnetic drive provided with a contactor and a disconnector both having at least one projection interacting with the main and auxiliary contacts through contact closing and disconnecting mechanisms having locks.
