Railway applications. Fixed installations. D.C. switchgear - Indoor d.c. disconnectors, switch-disconnectors and earthing switches LONG_TITLE BS EN 60603-7-4:2010 includes some1 Scope This part of EN 50123 specifies requirements for d. c. disconnectors, switch disconnectors and earthing switches for use in indoor fixed installations of traction systems. NOTE 1 Switchgear assemblies, electromagnetic compatibility (EMC) and dependability are not covered in this part of EN 50123, but rather by other parts of this standard or other documents as indicated in EN 501231. NOTE 2 In this standard the word "unit" means "disconnector
