Abstract

First (1) and second (2) contact pieces (CP) move in relation to each other via a drive mechanism. During a switch-off process, an electric arc (EA) (4) forms between the CP in a quenching zone (3) between the CP. A heating volume (5) retains a quenching gas heated by the EA. There are first (7) and second (8) compression volumes. An independent claim is also included for a.
