摘要：
A contact system for power circuit breakers includes a nozzle body made of graphite which is pressed cold into a tube of cold-worked copper and is enclosed by the latter with a friction fit. A low-alloy copper is used as the material for the electrically conducting tube. Such a copper alloy can be made, for example, with 0.1 percent silver.
