DIN CLC/TS 50152-4 VDE V 0115-320-4:2024-01

This document specifies requirements for prefabricated metal-enclosed traction switchgear for alternating current with traction voltages and frequencies as specified in EN 50163:2004 and used in indoor and outdoor installations. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation.
For metal-enclosed traction switchgear containing gas-filled compartments, the design pressure is limited to a maximum of 300 kPa (relative pressure).
Components contained in metal-enclosed traction switchgear are to be designed and tested in accordance with their various relevant standards. This document supplements the standards for the individual components regarding their installation in traction switchgear assemblies.
This document does not preclude that other equipment may be included in the same enclosure. In such a case, any possible influence of that equipment on the traction switchgear is to be taken into account.
