Overview
EN 50123-3:2003/A1:2013 is a CENELEC amendment to the European standard for railway fixed installations - D.C. switchgear. Part 3 specifically covers indoor d.c. disconnectors, switch-disconnectors and earthing switches used in traction and fixed railway electrical systems. The amendment was approved on 2013-08-26 and adopted for national implementation (dop 2014-08-26; dow 2016-08-26). The document is published in English, French and German and is under CLC/TC 9X.
Key Topics
- Scope and device types: Indoor D.C. disconnectors, switch-disconnectors and earthing switches intended for fixed railway installations.
- Performance and safety requirements: Sets out requirements relevant to electrical and mechanical behaviour of indoor D.C. switching and earthing devices (design, operation and safety aspects).
- Currents clause amendment: The A1 amendment makes a specific change to Clause 5.3.3 (“Currents”) - deleting the factor “1,2” in the first dash item under the third bullet - reflecting an update to how certain current-related requirements are applied.
- Standardization context: Aligned with CENELEC procedures and intended to be transposed as national standards by member bodies. Classified under ICS codes 29.280 (electric traction equipment) and 29.130.99 (other switchgear and controlgear).
Applications
- Design and specification: Electrical designers and system integrators use EN 50123-3 when specifying indoor DC disconnecting and earthing devices for substations, depot equipment rooms and other fixed installations.
- Manufacturers: Component and switchgear manufacturers reference the standard for product development, conformity and technical documentation.
- Testing and certification: Test laboratories and conformity assessment bodies use the standard to verify that indoor d.c. switchgear meets required performance and safety characteristics.
- Procurement and maintenance: Asset owners, operators and maintenance teams rely on the standard to ensure compatibility, safe isolation and earthing procedures in DC railway power systems.
