FIELD: electricity.

SUBSTANCE: invention may be used as a component of other electric equipment, drawer cubicles of switching devices, magnetic stations, including explosion-proof ones. Vacuum contactor comprises body, vacuum arc-quenching chambers, traction insulators, electromagnetic drive of direct action with connected freely installed pushers of connection/pressing, disconnecting rods and anchor. Anchor is fixed on disconnecting stems by means of nuts. Contactor is arranged with the possibility to locate flexible and rigid current-conducting buses at any side of body, and also to input sensors, for instance, current ones - "Rogovskiy's belt", which are installed on current-conducting parts and are poured with dielectric compound. Heat sink is done through current-conducting buses.

EFFECT: reduced dimensions, improved resource and reliability of contactor.
