Railway applications. Fixed installations. D.C. switchgear - General Ingestion-build-48024 thereby providing additional thermal insulation1 Scope The EN 50123 series specifies requirements for d. c. switchgear and controlgear and is intended to be used in fixed electrical installations with nominal voltage not exceeding 3 000 V d. c., which supply electrical power to vehicles for public guided transport, i. e. railway vehicles, tramway vehicles, underground vehicles and trolley buses. Part 1 specifies general requirements. The other parts are covering Part 2 D. C. circuit breakers, Part
