ABSTRACT:
This power breaker has an arcing chamber which is filled with an insulating medium and extends along a central axis (2). This arcing chamber is provided with a power current path which has two erosion contact arrangements (5, 6) which are arranged on the central axis (2), are at a constant distance from one another in the axial direction and bound an arcing zone. The arcing chamber also has a heating area (13), which is connected to the arcing zone, and a bridging contact which electrically conductively connects the erosion contact arrangements (5, 6) in the connected state. The bridging contact is arranged centrally in the interior of the erosion contact arrangements (5, 6). An annular gap (36) is provided between the erosion contact arrangements (5, 6) and opens directly into the heating area (13). In this power breaker, the flow behavior is significantly improved in the region between the arcing zone and the heating area (13).
