Abstract

A new vacuum switching chamber is intended for power breakers in the low-voltage range and is distinguished by a compact form with a small physical height and a high switching capacity. Its enclosure includes a plate-like power current connection, a cylindrical wall part which surrounds flat spiral contacts, an annular insulator and a membrane disk with a centrally arranged power current supply bolt.
