Abstract: Getter device for positioning in a vacuum interior space (12) of a vacuum circuit breaker (10). The getter device comprises at least one tablet (2) of getter material. The interior space (12) comprises a metal wall (13, 16. 11, 17, 19, 21) with a groove (4) in which the at least one tablet (2) can be placed, and the at least one tablet (2) can be fixed by at least one depression in an edge (7; 9) of the groove (4). The metal wall may be formed by a contact pin (13, 16) of one of the contacts (14, 15) or a wall of the enclosure, which comprises an end cap (11), a first shielding (17), a second shielding (19) or a second end cap (21).

Abstract: Ceramic tube for use in a vacuum circuit breaker, the ceramic tube (10) being cylindrical in shape with a set length and a set internal diameter. Furthermore, the ceramic tube has a cylindrical end face (11) at each end of the cylinder shape, it being possible for a metal end cap (4, 6) to be secured in a vacuum-tight manner to each cylindrical end face (11) in order to form a vacuum chamber (8). The cylindrical end face (11) is shaped in such a manner that, in the assembled state, it makes contact with the metal end cap (4, 6) at least as far as the internal diameter of the ceramic tube (10).
