Application Summary AI generated

This standard specifies the basic dimensional series for subracks and plug-in units with a vertical increment of 44.45mm (1.75 inches). It is applied in the design and manufacturing of electronic equipment enclosures, such as those used in telecommunications, data centers, and industrial control systems, to ensure mechanical interchangeability and compatibility between subracks and plug-in modules. The standard facilitates modular assembly and rack-mount integration in 19-inch rack systems.
