Abstract

Die vorliegende Erfindung betrifft einen NH-Sicherungslasttrenner oder eine NH-Sicherungslastschaltleiste mit einem Gehäuse mit einer Bodenfläche und mindestens einem Einspeisekontakt der über die Bodenfläche vorsteht. Um einen NH-Sicherungslasttrennschalter der eingangs genannten Art zur Verfügung zu stellen, die die Aufnahme von Stromwandlern erlaubt, ohne dass die Bauhöhe verändert wird, wobei die Einrichtung derart ausgebildet sein soll, dass Stromwandler ohne eigenen Primärleiter verwendet werden können, wird erfindungsgemäß vorgeschlagen daß mindestens ein Befestigungselement an der Bodenfläche beabstandet vom Einspeisekontakt über diese vorstehend angeordnet ist, wobei vorzugsweise das Befestigungselement derart ausgebildet ist, dass es mindestens eine Anschlagsfläche zur Anlage eines den Einspeisekontakt umgebenden Stromwandlers aufweist.

The present invention relates to an NH fuse switch disconnector or NH fuse switch disconnector comprising a housing having a bottom surface and at least one feeding contact projecting over the bottom surface. In order to provide an NH fuse switch disconnector of the type mentioned above, which allows the inclusion of current transformers, without the height is changed, the device should be designed such that current transformer without its own primary conductor can be used, the invention proposes that at least a fastener on the bottom surface spaced from the feed contact on this projecting, wherein preferably the fastener is formed such that it has at least one abutment surface for contacting a power converter surrounding the feed contact.
