The mrdb file extension is associated with modeling applications such as E3.series, E3.WireWorks, and other software developed by Zuken. These Windows applications are used to design and document electrical wiring and control systems.
An mrdb file stores manufacturing rules and related library data used by Zuken apps. The rules are maintained as part of the application's design environment and support manufacturing-related information.
This is a software-specific data file rather than a general-purpose interchange format. It is intended to be used with the Zuken application and compatible version or configuration that created or manages the library.
Open an mrdb file from within E3.series or E3.WireWorks on Microsoft Windows. The file may need to be placed in the application's configured library location or selected through its library-management tools.
It is not intended to be read as a standalone document. If the file does not load, use the Zuken software installation and library configuration associated with it rather than opening it in a text editor or unrelated database program.
The mrdb file is a software-specific manufacturing rule library rather than a document format designed for conversion between applications.
To transfer the library, use the import, export, or library-management features provided by the installed version of E3.series or E3.WireWorks, if those features support the required library data. Otherwise, keep the file in its original format and use it with compatible Zuken software.
