Specifies requirements for d.c. switchgear and controlgear. Meant to be used in fixed electrical installations, with nominal voltage not over 3,000 V d.c. which supply electrical power to vehicles for public guided transport.

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 3 Indoor d.c. disconnectors, switch-disconnectors and earthing switches,
Part 4 Outdoor d.c. disconnectors, switch-disconnectors and earthing switches,
Part 5 Surge arresters and low voltage limiters for specific use in d.c. systems,
Part 6 D.C. switchgear assemblies,
Part 7-1 Measurement, control and protection devices for specific use in d.c. traction systems – Application guide,
Part 7-2 Measurement, control and protection devices for specific use in d.c. traction systems – Isolating current transducers and other current measuring devices,
Part 7-3 Measurement, control and protection devices for specific use in d.c. traction systems – Isolating voltage transducers and other voltage measuring devices
