To date, DIN racks are distinguished by technical characteristics such as size, shape, material of manufacture and design features. The first thing to begin with is the types of profiles that can be:
- Ω-shaped. The most popular form used in switchboards for automata, electricity meter, etc. It looks like the picture:
- C-shaped. The ends are folded inwards, so that you can install hardware clamps or terminal blocks on such a DIN-rail.
- G-shaped. It is used extremely rarely, according to its intended purpose, corresponds to a rail in the form of C.
As for dimensions, according to the standard GOST R IEC 60715-2003, the width and height of the product can be as follows:
Please note that the DIN rail is in the form of an omega, which alsocalled TN-35( generally accepted designation), can have three dimensions, namely:
The length varies, depending on the manufacturer. Most often, slats with a length of 7.5 cm to 2 meters are produced, which is quite enough for shields from 4 to 96 modules.
It should also be noted that the strips are perforated( with holes) and cast. The advantage of the former is that it is easier to install;it is enough to simply screw the steel strip through the finished holes. The perforation step is usually 10-15 mm, which is quite enough for convenient installation. Molded( non-perforated) DIN-rails are more reliable, becauseDo not bend, if they fix many automatic devices in the cabinet. By the way, the modular automatons are fastened to the DIN rail as follows:
According to the fabrication material, the strips are divided into aluminum and galvanized( stainless steel).In electrical work, the second option is often used.
In addition, there are separate types of DIN-rails, namely: recessed and reinforced. Each of them is applied in its special case.
Well, the last thing I would like to tell you is which manufacturers of slats are considered the most optimal in price and quality. Among electricians, DIN-rails produced by ABB, IEK and DKS are popular. These firms have rather good products and at the same time a moderate cost.
It only remains to watch the video, which clearly shows how to mount the machine on the DIN-rail, and what is the difference between the manufacturers:
manufacturers That's all I wanted to tell you about the types and sizes of the DIN-shelves. Now you know what kind of bars there are, how they differ from each other well and for what they are actually used!
