Abstract

A high-voltage compressed-gas circuit breaker has contact plates with a contact face for the incoming cables. The position of these contact faces and the attachment bores on the contact faces for the connection of cables will vary depending on the form of installation given in the switching equipment. The circuit breaker has contact faces which are formed as contact parts which are separate from the terminal plates. On both contact parts, bores are provided for connecting the contact part and the terminal plate to each other, these bores protruding beyond the outside diameter of the interrupter unit on which the terminal plate is applied. The bores make possible a reversal of the contact face by 180.degree..
