Embodiment Construction

[0028] figure 1 An exemplary embodiment of a mounting plate 1 according to the invention is shown. The mounting plate 1 according to the invention is preferably rectangular and has four sides 2 , 3 , 4 , 5 , two sides 2 , 4 and 3 , 5 each lying opposite each other in parallel. Preferably, perforations 6 or recesses 7 are respectively provided in the corners of the mounting plate 1, said perforations or recesses realizing a complete structural unit consisting of a star-delta wiring arrangement with contacts on the mounting plate 1, eg Final assembly in switchgear. A plurality of small holes 8 are provided distributed over the mounting plate 1 as fastening possibilities for the various star-triangular superstructures.

[0029] Furthermore, an injection-molded, snap-off extension 9 is provided on the side 3 , which is required, for example, for a design with a timing relay. The extension 9 is preferably designed to correspond to the length of the side 3 to which it is fastened...

Abstract

The invention relates to a star-delta wiring, in particular for a protective circuit that is arranged on a mounting plate (1). The invention is characterized in that the mounting plate (1) is made of plastic.

Description

technical field [0001] The invention relates to a star-delta arrangement, in particular for a protective circuit arranged on a mounting board. Background technique [0002] For this purpose, DE 195 11 648 A1 discloses a mounting plate for an insert of a low-voltage switching device, which is formed from sheet metal. The mounting plate consists of two one-piece sections, which are separated by two bending lines. Here, the first section later forms the front side, while the second section is the rear side of the mounting plate. Furthermore, the mounting plate consists of a laterally arranged protective surface for the cable guide part and a bottom-side fastening tongue for fastening on the insert bottom, wherein the protective surface and the fastening tongue are present on the second on a section. The mounting plate is provided with lateral cutouts, which are provided later for the lead-through of cables. The second section is provided with fastening tabs riveted to the b...
