Housing Assembly and Electrical Switching Device, in Particular a Contactor or a Relay

Abstract

A housing assembly for a contactor, wherein the housing assembly comprises a frame made of ferromagnetic material surrounding a contact chamber for separable contacts of the contactor, and an encloser made of insulative material at least in sections enveloping the frame internally and externally, wherein the encloser comprises at least one pocket for receiving a blow-out magnet of the contactor, wherein the frame is at least sectionwise exposed for contact in the at least one pocket. The frame improves the mechanical stability of the housing assembly and offers a suitable path for conducting the magnetic flux from the blow-out magnet. Further, the present invention relates to an electrical switching device with such a housing assembly.
