| 摘要 |
The invention relates to a circuit breaker comprising a first contact (4) and a second contact (5). An electric arc zone is disposed between the contacts (4, 5). A feed channel (13) opens into the electric arc zone, connecting the electric arc zone to a hot gas reservoir volume (14). The hot gas reservoir volume (14), in turn, is connected to a compression volume (18). An outflow opening (20a, 20b, 20c, 20d, 20e, 20f, 20g, 20h) is disposed in a wall (8) of the compression volume (18). The outflow opening (20a, 20b, 20c, 20d, 20e, 20f, 20g, 20h) is permanently open at least in the contacting state of the contacts (4, 5). |
