Foreword
This document (EN 50152-1:2012) has been prepared by CLC/SC 9XC "Electric supply and earthing
systems for public transport equipment and ancillary apparatus (Fixed installations)".
The following dates are fixed:
• latest date by which this document has to be (dop) 2013-10-15
implemented at national level by publication of
an identical national standard or by
endorsement
(dow) 2015-10-15
• latest date by which the national standards
conflicting with this document have to
be withdrawn
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 50152-1:2007.
This standard was revised to reflect the latest versions of standards referenced and to remove text already
included in the EN 62271 series. The scope was extended to include single-phase and two-phase circuit
breakers. Definitions were added to provide the necessary precision and to meet the needs of railway
applications. Table 1 was reworked according to the changes of EN 50124-1:2001, Table A.2 and Table B.1.
Standard values of transient recovery voltage have been taken from different tables to one, Table 2. Ratings
of mechanical endurance previously given under the clause ‘type tests’ were moved to the new Table 4
‘Mechanical endurance classes’. Standard values of prospective transient recovery voltage have been taken
from different tables to one, Table 5. Table 6 ‘Coordination table of rated values for circuit-breakers’ of the
previous version was removed.
EN 50152 series under the generic title Railway applications  Fixed installations  Particular requirements
for alternating current switchgear is divided as follows:
- Part 1: Circuit-breakers with nominal voltage above 1 kV;
- Part 2: Disconnectors, earthing switches and switches with nominal voltage above 1 kV;
- Part 3-1: Measurement, control and protection devices for specific use in a.c. traction systems 
Application guide;
- Part 3-2: Measurement, control and protection devices for specific use in a.c. traction systems  Single-
phase current transformers;
- Part 3-3: Measurement, control and protection devices for specific use in a.c. traction systems  Single-
phase inductive voltage transformers.

Introduction
This standard needs to be read in conjunction with EN 62271-1:2008 and EN 62271-100:2009.
Where a particular clause of EN 62271-100 is not mentioned in this standard, that clause applies as far as
reasonable. Where requirements relate exclusively to three-phase systems or to voltages outside those in
use in traction systems, they are not applicable. Where this standard states "addition" or "replacement", the
relevant text of EN 62271-100 needs to be adapted accordingly.
The numbering of clauses in EN 62271 series is not used in this European Standard. The numbering in
square brackets refers to the numbering of clauses in EN 62271.
