  • Patent number: 8932089
    Abstract: A connecting arrangement is disclosed for an electrical switching device for attaching an electrical connection to the electrical switching device, including a terminal, a fixing screw and a terminal screw including an external thread. The terminal includes a connection opening for introducing the electrical connection, a fixing opening through which the fixing screw can be passed for the purpose of securing the terminal to an electrical contact of the electrical switching device, and a terminal bore having an internal thread through which the terminal screw can be screwed in for the purpose of retaining the electrical connection. The terminal screw includes a through-hole and, arranged concentrically with respect to the through-hole, a blind hole which is embodied for receiving a turning tool. The blind hole covers the through-hole and has a greater cross-sectional area than the through-hole. An electrical switching device including at least one such connecting arrangement is disclosed.

  • Publication number: 20120152704
    Abstract: A casing of a circuit breaker for nominal currents above 250A that enables at least one rigid busbar to be swung in to make contact with at least one switching pole attached in the casing. The casing may include a bottom section that cuboidally includes a rectangular base area and two rectangular side faces connected to the base area and running parallel to one another. Adjacent side faces are connected to one another via at least two stays which are arranged away from the opposing openings, delimited by the side faces, of the cuboidal bottom section, so that a switching pole can be inserted between the stays into the bottom section and so that a rigid busbar can be swung in at one of the two openings in order to make contact with the switching pole, when busbar and bottom section are each premounted, for example in a switching cabinet.
