Movable contact support for LV switchgear with energy transfer drive

摘要

The drive transmits the switching energy from drive of the LV switchgear to the movable contact support (1) via a mechanical coupling member (8) hinged to the contact support. Between the coupling member and the contact support there is a positive connection without extra elements.The positive connection is formed by a circular pocket (7) in the contact support and the coupling member, which comprises a circular disc (10) providing the hinging function and fitted into the pocket.
