DIN rails
Modern electrical work, both in industry and in the residential construction sector, cannot happen without a DIN rail. What is a DIN rail? What does she look like?

History of the DIN rail

DIN rail developed in Germany. The abbreviation DIN stands for Deutsches Institut für Normung, which in Bulgarian is German Institute for Standardization. DIN is a German registered association based in Berlin. There are currently around thirty thousand DIN standards covering almost every field of technology .

The original concept was developed and implemented in Germany in 1928. and was developed into current standards in the 1950s. The DIN rail proved to be a successful invention and quickly gained popularity. Subsequently, it was also accepted by the International Electrotechnical Commission (IEC) and legitimized as a European standard (EN).

The DIN rail has changed the electrical equipment of the dashboard worldwide. A modern installation requires a constructive approach to automation, not only commercial and office areas, but also internal network wiring.
Now, all modern automation devices are specially designed for DIN rail, so they are easy to install. Installation of a module can take only a few seconds. A DIN rail is usually provided by the manufacturer as an integral element. But when it is necessary to install a DIN rail yourself, it will not be too difficult: the rails have perforated holes that allow the product to be fixed with screws or bolted joints in a specially equipped place.

What is the DIN rail made of?

The DIN rail is made of steel with a protective zinc coating on the metal product, incl. coatings of steel and other iron alloys. This is the so-called galvanized steel.

Types of DIN rails

There are three main types of DIN rail

• Type O or Type Ω
• Type "C"
• Type “G”

DIN rail Type O or Type Ω - IEC / EN 60715

This 35 mm rail is widely used for mounting electrical fastening systems, circuit elements such as circuit breakers, circuit breakers, differential switches, timers, contactors, relays, etc. The D IN bus is an integral part of the design of distribution boards, installation boxes. The EN 60715 standard is divided into two types with a depth of 7.5 mm and a depth of 15 mm, which are officially designated
DIN rail IEC / EN 60715 - 35 × 7.5
DIN rail IEC / EN 60715 - 35 × 15

The width of devices that are mounted on a 35 mm "cylinder" DIN rail usually use "modules" as the unit of width, with one module being 17.5 mm wide. For example, a small device (e.g. circuit breaker) may be 1 module wide (17.5 mm wide), while a larger device may be 4 modules wide (4 * 17.5 = 70 mm wide). Equipment enclosures also follow these module widths, so a DIN rail enclosure can have space for 20 modules, for example. Not all devices follow these module widths. Module widths are usually abbreviated as "M" (eg 4M = 4 modules) . Some manufacturers (including Mean Well) use "SU" (probably meaning "standard unit", eg 4SU = 4 modules) .

DIN rail Type "C"

These DIN rails are symmetrical within the given tolerances. There are four popular C-section rails, C20, C30, C40 and C50. The numerical suffix corresponds to the total vertical height of the rail.

DIN rail Type " G "

The G-rail is typically used to hold heavier, higher power components. It is mounted with the deeper side below and the equipment is hooked onto the lip, then rotated until it is hooked into the shallower side.

In addition to the popular 35 mm × 7.5 mm top hat rail (EN 50022, BS 5584, DIN 46277-3), several lesser-used types of mounting rails have also been standardized:

Miniature DIN rail, 15 mm × 5.5 mm (EN 50045, BS 6273, DIN 46277-2);
75 mm wide DIN rail (EN 50023, BS 5585);

How to choose a DIN rail

Choosing a DIN rail will not be difficult for you after learning all this about them, but still let it be done by a professional who will then install it, along with the modules on it. Still, you can't go wrong if you get a DIN rail standardized for the country you live in. For Bulgaria, the most frequently used dimensions are those offered by us, a DIN rail with a height of 35mm, a depth of 7.5mm and a length of 1.0m. and a DIN rail with a height of 35mm, a depth of 7.5mm and a length of 0.25m.
