Abstract

Es wird eine magnetische Auslöseeinrichtung für einen Fehlerstromschutzschalter beschrieben, bei der im Fehlerstromfall in einer Spule durch den Fehlerstrom ein magnetischer Fluß erzeugt wird, der dem magnetischen Fluß eines Permanentmagnetsystems entgegenwirkt, so daß die magnetische Haltekraft des Permanentmagnetsystems auf ein bewegliches Bauelement, wie beispielsweise einen Klappanker, so weit herabgesetzt wird, daß das bewegliche Bauelement durch die Kraft einer Feder in eine Auslöseposition hin bewegt wird, in der dann ein Schaltschloss betätigt wird, und bei der zur Erhöhung der Auslösezuverlässigkeit die Stoß- und/oder Gleitkontaktstellen an dem festen und/oder beweglichen Bauelement mit einer dichten, gegen Wasser, Öle, Fette und Silikone beständigen Passivierungsschicht beschichtet sind, deren Dicke einen Bruchteil der Ausdehnung des Arbeitsluftspaltes des Permanentmagnetsystems, typischerweise 10 - 500nm, beträgt.

A magnetic tripping device for a residual current circuit breaker is described, in which, in the event of a residual current, a magnetic flux is generated in a coil by the residual current, which counteracts the magnetic flux of a permanent magnet system, so that the magnetic holding force of the permanent magnet system on a movable component, such as a hinged armature , is reduced so far that the movable component is moved by the force of a spring into a trigger position, in which a key switch is then actuated, and in which to increase the trigger reliability, the impact and / or sliding contact points on the fixed and / or movable component are coated with a dense passivation layer resistant to water, oils, greases and silicones, the thickness of which is a fraction of the extent of the working air gap of the permanent magnet system, typically 10-500 nm.
