Abstract

A high-voltage compressed-gas circuit breaker having terminal plates with a contact face for incoming cables. The position of these contact faces and the attachment devices on the contact faces for the connection of the cables varies according to the form of installation given in the switching equipment. The contact faces are formed as a separate part from the terminal plate. On both the separate part and the terminal plate, bores for connection of the part and the plate are provided which do not affect the sealing by the terminal plates of the interior of the interrupter unit at its outer end faces. The bores permit an attachment of the separate part to the contact face in either a first position, or a second position which is rotated by 90.degree. from said first position.
