Problems solved by technology

[0006] A disadvantage of the prior art is that the adhesive connection is always subject to aging processes and, moreover, the installation is expensive, since for the adhesive connection it is always necessary to guide the two parts exactly to one another.

Embodiment Construction

[0021] figure 1 shows a partial area of ​​a circuit breaker with a housing consisting of a housing lower part 1 in which a first switching device area is arranged and a housing upper part 2 in which a second switching device area is arranged. exist figure 1 The form-fitting connection between housing lower part 1 and housing upper part 2 is shown in . Cooling fins 4 are arranged in the housing undercut 3 of the housing inner wall in the region of the housing upper part 2 , which are positioned on a baffle insert 5 inside the interrupter arrangement. In addition, the preferably U-shaped fixed switching contact element 6 is fixed on the cover insert 5 via the arm 8 of the fixed switching contact element 6 with the two arms 7 , 8 and the transition region 9 connecting the two arms 7 , 8 . The transition region 9 of the fixed switching contact element 6 is positioned here in a barb-like housing structure 10 which preferably protrudes out of the housing lower part 1 in an L-shap...

Abstract

The invention relates to a circuit breaker with a housing. A first switching device region and a second switching device region are arranged in the housing. The first switching device region comprises an arcing chamber device and a contact slider device with movable switch contact elements. Fixed switch contact elements are positioned opposite to the movable switch contact elements. A current trigger pulse group with short circuit and overload triggers is arranged in the second switching device region. The invention is characterized in that a diaphragm insert (5) is arranged in the arcing chamber device of the first switching device region and comprises at least one accurately-fit spacer (11) that are arranged between housing walls, where the walls are arranged parallel to two arcing metal sheets (13) of the arcing chamber device in the first switching device region.

Description

technical field [0001] The invention relates to a circuit breaker with a housing, in which a first switching device area and a second switching device area are arranged, in which an arc extinguishing chamber arrangement is arranged and a movable switch is arranged. Contact slider arrangement of the contact element, the movable switching contact element is positioned opposite the fixed switching contact element, the current release consisting of the short-circuit release and the overload release is arranged in the second switching device area components. Background technique [0002] Circuit breakers, especially low-voltage circuit breakers, are electromagnetic automatic switches in the event of a short circuit. Its working principle corresponds theoretically to that of a line protection switch. Most of these circuit breakers are designed with a thermal and magnetic release and therefore have the same structural elements as circuit breakers. Although designed for higher se...
