Embodiment Construction

[0023] The contactor shown in FIG. 1 is an electromagnetic switching device and has an exciting coil 1 . This excitation coil 1 is inductively coupled with a yoke 2 and an armature 3 . If an inrush current I is applied to the exciting coil 1, the armature 3 will be shifted to a pull-in position, as shown by the arrow A in FIG. 1 . In this way, at first one contact 4 is actuated, ie the contact 4 is thus closed. In this way, an electrical connection is established between the conductors 5 connected to the contacts 4 .

[0024] Excitation coil 1 , yoke 2 , armature 3 , contacts 4 and conductors 5 are accommodated in a base 6 of a housing. The housing bottom 6 is detachably connected to a housing top 7 by means of fastening elements 8 which are only schematically represented in FIG. 1 . The housing bottom 6 and the housing top 7 together form the housing 6+7 of the electromagnetic switching device.

Abstract

A drive solenoid (1), a yoke (2), an armature (3) and at least one contact (4) are mounted in a housing (6+7) of an electromagnetic switching device. The drive solenoid (1), yoke (2) and armature (3) are inductively intercoupled, in such a way that when an inrush current (I) is applied to the drive solenoid (1), the armature (3) can be displaced into a pickup position, thus directly or indirectly actuating the contact (4). The yoke (2) and / or armature (3) contain(s) pulverulent magnetic material (9).

Description

technical field [0001] The invention relates to an electromagnetic switching device, in particular a contactor or circuit breaker, which has a housing, a field coil, a yoke, an armature and at least one contact, [0002] wherein the excitation coil, the yoke, the armature and at least one contact are arranged in the housing, [0003] wherein the field coil, the yoke and the armature are inductively coupled to each other, so that the armature can be shifted to an attractive position by applying an inrush current to the field coil, [0004] Wherein, the contact point can be directly or indirectly controlled by the shifting of the armature to the suction position. Background technique [0005] The above-mentioned electromagnetic switching devices are well known, and in particular all contactors and circuit breakers have such a structure. [0006] Magnetic switching devices, such as circuit breakers and contactors, have an electromagnetic drive consisting of a coil, a yoke and...
