This European Standard is applicable to new low voltage devices for measurement, control and protection which are:
-
for indoor or outdoor fixed installations in traction systems, and
-
operated in conjunction with high voltage equipment with an a.c. line voltage and frequency as specified in EN 50163 .
EN 50163 specifies the a.c. traction systems 15 kV 16,7 Hz and 25 kV 50 Hz.
This European Standard also applies to measurement, control and protective devices other than low voltage devices and not covered by a specific railway product standard as far as reasonably possible. Requirements of this document prevail.
