Embodiment Construction

[0077] FIG. 1 shows a perspective view of a magnetic trigger device 100 known from the prior art in a perspective view. The magnetic trigger device 100 has an armature element 101, a spring element 102 and a yoke element 103. The yoke element 103 is shaped such that the respective yoke clamps 103.1 and 103.2 have gaps 103.3 or hook-shaped protrusions 103.4 and 103.5, which are formed for arranging the armature element 101 at all. The holding area on the yoke element 103. The armature element 101 is therefore arranged on the yoke element 103 itself and is connected to this yoke element 103 in a movable manner. The spring element 102 is inserted with the first spring element end 102.1 into a cross pin 104 which extends in the area below the yoke element 103. The spring element 102 is inserted with the second spring element end 102.2 into the insertion area 101.3 of the armature element 101, which is formed between the first armature element end 101.1 and the second armature ele...

Abstract

An overcurrent tripping device of an electrical switch for interrupting a current flow in an electrical circuit in the event of the occurrence of an overload or a short circuit is disclosed. In an embodiment, the overcurrent tripping device includes a thermal tripping device and a magnetic tripping device. A magnetic tripping device is disclosed which, in an embodiment, includes at least one yoke element for generating a magnetic field, an armature element responding to the magnetic field, and a spring element. The armature element is arranged on an armature carrier element, separated from the yoke element, by way of a first armature element end and is mounted pivotably about an armature element rotation axis. In addition, an electrical switch including an overcurrent tripping device, and a method for calibrating magnetic tripping of a magnetic tripping device of an electrical switch, are disclosed.

Description

Technical field [0001] The present invention relates to a magnetic trigger device of an electrical switch for interrupting the current flux of an electrical switch circuit when a short circuit occurs, and an overcurrent trigger device of an electrical switch for interrupting the current flux of the electrical switch circuit when an overload or short circuit occurs. In addition, the present invention relates to an electrical switch and in particular to an electrical power switch for interrupting the current flux of an electrical switching circuit when an overload or a short circuit occurs, and a method for calibrating the magnetic trigger of a magnetic trigger device. Background technique [0002] Basically, we know, for example, to design a compact power switch (MCCB=Molded Case Circuit Breaker) based on the principle of magnetic mutual exclusion of contacts. Here, the contact opens before the approximate possible peak value of the short-circuit current is reached. Due to the ma...
