Abstract: A switching unit for an electrical switch is disclosed. In an embodiment, the switching unit includes at least one fixed contact and one moveable contact with a current feed, which in order to close or open the current path are respectively brought into mechanical contact with each other or mechanically or magnetically separated from each other. The switching unit further includes at least one extinguishing plate, which affects an electrical arc created when the electrical contacts are opened. The current feed to the moveable contact is designed such that in the open position it directs the current along the electrical arc in the opposite direction to the current direction of the arc.

Abstract: A thermomagnetic trip is disclosed for an electrical switching device, especially a circuit breaker. In at least one embodiment it includes at least one first and one second terminal, a first heating element, a conductor able to be influenced by temperature, a yoke and a clapper armature. A current path is formed through at least the first terminal, the conductor, the first heating element and the second terminal. The current path is disposed at least in sections on and/or in the yoke such that a magnetic field acting on the clapper armature is induced in the yoke by the current flowing through the current path and wherein a second heating element is disposed in the current path especially between the first terminal and the conductor.

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 ? of less than 90° relative to one another.
