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 triggering device 100 has an armature element 101 , a spring element 102 and a yoke element 103 . The yoke element 103 is shaped in such a way that the respective yoke clips 103.1 and 103.2 have recesses 103.3 or hook-shaped projections 103.4 and 103.5, by means of which projections are formed for arranging the armature element 101 on the The holding area on the yoke element 103 described above. Armature element 101 is therefore arranged on yoke element 103 itself and is movably connected to this yoke element 103 . The spring element 102 is inserted with a first spring element end 102 . 1 into a cross pin 104 which extends in the lower region of the yoke element 103 . The spring element 102 is inserted with a second spring element end 102.2 into an insertion region 101.3 of the armature element 101 which is formed between the first armature ele...

Abstract

The invention relates to an overcurrent triggering device for an electrical switch, which is used to interrupt the current flux of an electrical switch circuit in the event of an overload or a short circuit, the overcurrent triggering device has a thermal triggering device and a magnetic triggering device; the invention also relates to a A magnetic triggering device having at least one yoke element for generating a magnetic field, an armature element reacting to said magnetic field, and a spring element, wherein the armature element is arranged by means of a first armature element end in relation to the The yoke element is mounted separately on the armature base unit and pivotable about the axis of rotation of the armature element. Furthermore, the invention relates to an electrical switch with an overcurrent tripping device and a method for calibrating the magnetic triggering of a magnetic tripping device of an electrical switch.

Description

technical field [0001] The invention relates to a magnetic triggering device of an electrical switch for interrupting the current flow of an electrical switching circuit in the event of a short circuit and an overcurrent triggering device of an electrical switch for interrupting the current flow of an electrical switching circuit in the event of an overload or a short circuit. Furthermore, the invention relates to an electrical switch and in particular to an electrical power switch for interrupting the current flow of an electrical switching circuit in the event of an overload or a short circuit and a method for calibrating the magnetic triggering of a magnetic triggering device. Background technique [0002] Basically know, for example, design a compact power switch (MCCB=Molded Case Circuit Breaker) based on the principle of magnetic mutual repulsion of the contacts. In this case, the contacts open before the approximately possible peak value of the short-circuit current i...
