Abstract

Die Erfindung betrifft eine Elektromagnetanordnung, insbesondere für den Einsatz in einem elektrischen Schaltgerät, mit einer Antriebsspule, mit einem feststehenden Magnetjoch (10) und einem bewegbaren Anker (60). Es wird vorgeschlagen, dass das Magnetjoch (10) und/oder der Anker (60) eine Beschichtung (30) aus einer schlagfesten Email oder einen schlagfesten Lack tragen. Eine Ausführung besteht darin, dass das unmagnetische, den Remanenzluftspalt (22) füllende Material (15, 15') eine schlagfeste Email oder ein schlagfester Lack ist.

The invention relates to an electromagnet arrangement, in particular for use in an electrical switching device, with a drive coil, with a fixed magnetic yoke (10) and a movable armature (60). It is proposed that the magnetic yoke (10) and / or the armature (60) carry a coating (30) of an impact-resistant enamel or an impact-resistant lacquer. One embodiment is that the non-magnetic, the remanence air gap (22) filling material (15, 15 ') is an impact-resistant enamel or impact resistant paint.
