BSI BS EN 50152-2:2012

This European Standard is applicable to single-pole and two-pole alternating current (a.c.) disconnectors, earthing switches and switches which are:

  • designed for indoor or outdoor fixed installations in tractions systems, and

  • operated with an a.c. line voltage and frequency as specified in ENĀ 50163.

    NOTEĀ 1 ENĀ 50163 specifies the a.c. traction systems 15Ā kV 16,7Ā Hz and 25Ā kV 50Ā Hz.

    NOTEĀ 2 As rails of a.c. traction systems are connected to earth and included in the return current path all phase to earth voltages will be within the tolerances as specified in ENĀ 50163. Nevertheless phase to phase voltages are sometimes higher, e.g. in autotransformer systems.

    NOTEĀ 3 The two poles of a switch can be connected in series to provide secure isolation (i.e. two breaks in series).
