Abstract

A hinged armature arrangement, for a magnetic tripping device of an electrical switching device, includes a yoke, a hinged armature and a hinged armature spring for embodying a spring force on the hinged armature. The hinged armature is mounted at a first end in a hinged armature bearing. The hinged armature bearing includes a contact surface and a stop surface. The hinged armature spring is arranged on the hinged armature such that at least one first part of the spring force acts against a magnetic force, which is exerted on the hinged armature when a current path is energized. In a particular embodiment, the contact surface and the stop surface are arranged at an angle α of less than 90° relative to one another.
