Abstract (en)
A gas-insulated high or medium voltage circuit breaker (100) comprising a first arcing contact (101) and a second arcing contact (103), wherein at least one of the two arcing contacts (101, 103) is axially movable along a switching axis (140), wherein during a breaking operation, an arc (130) between the first arcing contact (101) and the second arcing contact (103) is formed in an arcing region. An electrically conductive armature (120) radially surrounds at least part of a diffuser portion (114) of the nozzle (110); an electrically conductive ring-like element (116) is mounted to the diffuser portion (114) and is slideable relative to the armature (120), and the ring-like element (116) is radially outwardly biased such that an outer side of the ring-like element (116) is pressed against the armature (120).
