Abstract

Ein Stromleiter (5, 6, 7) einer NH-Sicherungs-Einrichtung oder NH-Sicherungs-Lastschalteinrichtung weist zwei parallele Abschnitte (5, 6) auf, von denen ein Abschnitt (6) mit einer Sammelschiene (3) und der andere Abschnitt (5) mit einem Kontakt (16) eines Poles verbindbar ist, und einen sich im rechten Winkel zu diesen erstreckenden und diese verbindenden Mittelteil (7). Die Abschnitte (5, 6) und der Mittelteil (7) mit einem zylindrischen Querschnitt (7) sind etwa Z-förmig angeordnet und der Stromwandler (14) ist am Mittelteil (7) angeordnet. Wenigstens einer der beiden Abschnitte (5, 6) ist mit dem Mittelteil (7), vorzugsweise lösbar, verbunden, um den Stromwandler (14) auf den Mittelteil (7) stecken zu können.

Figure 00000001
A current conductor (5, 6, 7) of an NH fuse device or NH fuse load switch device has two parallel sections (5, 6), one section (6) of which has a busbar (3) and the other section ( 5) can be connected to a contact (16) of a pole, and a central part (7) extending at right angles to and connecting them. The sections (5, 6) and the central part (7) with a cylindrical cross section (7) are arranged approximately in a Z-shape and the current transformer (14) is arranged on the central part (7). At least one of the two sections (5, 6) is connected to the central part (7), preferably detachably, in order to be able to plug the current transformer (14) onto the central part (7).
