| 摘要 |
The invention relates to an electric switching device having a housing (2) made of electrically insulating material, wherein current paths (4a, 4b, 4c) associated with three different phases of a three-phase system are provided. Said current paths each comprise a contact region (14) with a contact bridge (6), wherein the current paths are thermally connected to each other via at least one thermal bridge (9, 9a, 9b, 9c) made at least partially of a material that has greater thermal conductivity than the material of the housing or than air.
