Distribution Boards: Easy and Reliable Planning

Schrack Design helps you to plan your electrical distribution board enclosures with ease and makes sure they comply with applicable standards. Besides creating assembly and wiring diagrams you can verify the thermal design of your planned distribution board according to IEC TR 60890 and thus meet a requirement of EN 61439 (up to 1600 A). Documentation is included and you have a database of over 10,000 products at your disposal.

Functions of Schrack Design

A new update is available for download, which makes our Schrack Design tool another notch faster, easier to use and more customisable to your individual requirements.
We have added the following features:

  • Customisable circuit directory (articles to include, configuration)
  • Improved wiring diagram (shortcuts, AFDD, ...)
  • Parts list can be minimised (faster handling) 
  • New symbols added for wiring diagram
  • Shortcuts available for more functionalities

We enhance and improve the functionalities of Schrack Design Software from time to time to make it both faster and easier to use. The extended functionalities now include:

  • Automatic single- or multi-line wiring diagram
  • Easy handling of large projects in an additional window
  • Export to Excel available for circuit directory
  • CSV import now includes notes
  • Contact table for contactors

There are over 10,000 products in the article database which you can use to design your project according to your requirements. You can add products from the article database, from your defined favourites, or from articles you have added yourself. You can use the search functionality to look for products using the article number, the name or simply keywords. When adding an article you can immediately specify the quantity you need. 

You can use the search functionality to look for products using the article number, the name or simply keywords. If you need to change the quantity of an article, you can do so when you select the product or afterwards for the defined products in the parts list (double-click on the article before you select it or - if already in the parts list - right-click on the article).

The Parts List functionality helps you to design one or several distribution boards independently from one another. It takes only a few steps to add or replace articles, change the quantity of an article or use pre-configured distribution boards.

If you select a modular distribution board with an article number for the complete enclosure (e.g.: EVN 3U24NE, IL164324NS), the system will display the parts list containing all the individual components of the enclosure. You can replace or remove individual articles from this list.

You can also use the outlined star icon to the right to define a product as a Favourite. It will be displayed in your personal article list (to the left of the product database) and will be available as a Favourite for you to use in future projects.

It is also possible to import a CSV file. This uploads your complete parts list into Schrack Design with a single click.

To design the front view of your distribution enclosure simply drag the icons of all the distribution board components into the drawing window "Front view" and position them as required or insert them automatically by double-clicking. These design icons of the articles are available in the parts list to the right of the article. If you use the double-click function to insert the drawing automatically, Schrack Design recognises when a row is full and automatically starts a new row.
If you use a pre-designed distribution panel, Schrack Design indicates where the front plates of the devices are and where it is possible to insert new articles.
By selecting an electrical component panel via its combined article number (e.g.: EVN 3U24NE, IL164324NS) you will automatically see the parts list with all its individual components as soon as you insert it.
Depending on your requirements, you can then modify the inserts in the distribution enclosure or replace individual components with others; e.g.: you might want to replace a slotted front plate 3G3 IL051303-H with a blind front plate 3B3 IL056303. To do so, simply search the product list and select the desired article.
The original set of articles of the distribution enclosure, however, remains in the list.

Create a single- or multi-line wiring diagram (one pole/3-pole) for your distribution board.

For RCD, MCB and RCBO the multi-line wiring diagram is generated automatically if the option "Automatic schema drawing" is selected in the settings. Clicking on the tab to create a 3-pole wiring diagram then automatically generates the diagram as specified by the front view.

Naturally, you can also add articles manually - proceed in the same way as with the front view and drag the icons of your distribution board articles into the drawing window. As in the design of the front view it is also possible to automatically align the icons next to each other. You can use the “angled line” tool to connect these symbols quickly and easily. There are several additional functionalities to support professional design planning. For example, it is possible to add a note to an article, which will be included automatically in the documentation (circuit directory). You can also link lines, which allows planning large projects. To avoid crossing lines all wiring icons can be individually edited, moved and placed.

Schrack Design monitors the temperature of the distribution board in real time and immediately displays a warning if the enclosure's temperature exceeds the allowed maximum.

This live thermal calculation is performed already when articles are added to the parts list. If the enclosure temperature exceeds the allowed maximum, the system displays a warning.

To recalibrate the distribution board, click on the icon that has turned red and follow the four steps of our Guide to make the system compliant with standards. Our Guide is a helpful assistant to solve the problem.

The Thermal Calculation Guide offers four easy steps which help you to recalibrate your distribution board to comply with standards.

In the first step, you can adjust influencing factors such as the ambient temperature, mounting type and reduction factor. These values have to match the actual conditions on site. It is also possible to replace the enclosure box and e.g. choose a larger or smaller body.

In the second step, you can add the busbars or adjust the length of previously added busbars to calculate the actual temperature. Adjusting the length automatically adjusts the power loss of the product.

In the third step you can add the wiring. To do so, you need to specify such data as the cross-section, installation method and length. The wiring calculation is then made automatically.

In the fourth step, the software will recommend a suitable ventilation system, if necessary, to lower the temperature to the range as specified in the standards. If you add this system to your project, all articles of the system are added to the parts list.

To print your IEC 890+A1 report for the distribution board simply use the print functionality. This Distribution Board/Test Report will contain the front view, wiring diagrams (multi- or single-line wiring diagram), parts list, positions table, circuit directory, declaration of conformity, and the power loss calculation according to IEC 890 + A1.

Last but not least the report will contain a rating plate with all the data you have provided for the calculated and rated distribution enclosure. Simply print the rating plate on a suitable printer (see section 8) and affix the plate inside the enclosure.

Schrack Design lets you print the rating plate of the distribution board quickly and efficiently!

We recommend the Ondot thermal transfer label printer TTP-245C for that purpose. If you are a Schrack Technik customer, you will receive special rates from Ondot when ordering the label printer. Send an email to info(at) with "Schrack Design" in the subject line.

You will find more details about the printer in the data sheet -

The documents related to a distribution enclosure must be archived for a period of 10 years to meet applicable legal provisions. To do so, you can save the project any time. In addition, it is possible to print the documentation in PDF format.

You can use the Export function to save the parts list of the project either as .txt or .xls. Thus, with only a few clicks you can save the report or export your parts list.

As soon as the distribution enclosure is finished and meeting the standards, you can simply order all the required Schrack products in the Online Shop. If you click on the basket, the system will put the parts list of your project in your Schrack Technik basket. You can then re-check all articles and quantities and modify them where necessary. Another click, and you have ordered the complete enclosure as designed.
