Abstract

Die Erfindung betrifft einen Messwandler (1), insbesondere Stromwandler, für ein elektrisches Gerät (2) und eine Anordnung mit einem solchen Messwandler (1) und einem elektrischen Gerät (2). Um eine einfache und dennoch sichere Befestigung eines Messwandlers (1) an einem elektrischen Gerät (2) zu ermöglichen wird vorgeschlagen, Wandlergehäuse (3) und Gerätegehäuse (31) derart auszugestalten, dass Messwandler (1) und elektrisches Gerät (2) unter Ausbildung einer Rast- oder Schnappverbindung miteinander verbunden werden können.

The invention relates to a measuring transducer (1), in particular current transformer, for an electrical device (2) and an arrangement with such a measuring transducer (1) and an electrical device (2). In order to enable a simple yet secure attachment of a transducer (1) to an electrical device (2), it is proposed to design the transducer housing (3) and device housing (31) in such a way that the transducer (1) and electrical device (2) form a Snap or snap connection can be connected together.
