Railway applications - Fixed installations - Particular requirements for a.c. switchgear - Part 1: Single-phase circuit-breakers with Un above 1 kV
This EN 50152-1 is applicable to single-phase a.c. one-pole circuit-breakers designed for indoor or outdoor fixed installations for operation at frequencies of 16,7 Hz and 50 Hz on traction systems having an UNm above 1 kV up to 52 kV. This EN 50152-1 is also applicable to two-pole circuit-breakers when connected in the following manner: one pole supplying the connection to the contact line of the track, the second pole supplying the connection to the feeder cable which runs alongside the same track and which is used to boost the track voltage at regular intervals in combination with autotransformers. The centre of this circuit is connected to earth. This European Standard is also applicable to the operating devices of circuit-breakers and to their auxiliary equipment. This European Standard does not address circuit-breakers with dependent manual operating mechanism. NOTE : A rated short-circuit making current cannot be specified for these circuit-breakers and the use of these mechanisms may give reasons for the objection based on their safety in operation.
Bahnanwendungen - Ortsfeste Anlagen - Besondere Anforderungen an Wechselstrom-Schalteinrichtungen - Teil 1: Einphasen-Leistungsschalter mit Un über 1 kV
EN 50152-1 gilt für einpolige Einphasen-Wechselstrom-Leistungsschalter, die für ortsfeste Innenraum- oder Freiluftanlagen ausgelegt sind sowie für den Betrieb in Bahnnetzen mit UNm über 1 kV bis 52 kV bei Frequenzen von 16,7 Hz und 50 Hz. EN 50152-1 gilt auch für zweipolige Leistungsschalter, wenn sie in folgender Weise angeschlossen werden: ein Pol speist die Verbindung zur Fahrleitung der Strecke, der andere Pol stellt die Verbindung zur Speiseleitung her, die entlang derselben Strecke verläuft, und die in regelmäßigen Abständen zur Stabilisierung der Streckenspannung in Verbindung mit Autotransformatoren verwendet wird. Der Mittelpunkt dieser Schaltung ist geerdet. Diese Europäische Norm gilt auch für Betätigungseinrichtungen der Leistungsschalter sowie deren Hilfseinrichtungen. Diese Europäische Norm gilt nicht für Leistungsschalter mit abhängigen manuellen Betätigungs-mechanismen. ANMERKUNG : Für diese Leistungsschalter kann kein Bemessungs-Kurzschluss-Einschaltstrom angegeben werden und gegen die Verwendung solcher Mechanismen können aus Sicherheitsgründen Einwände vorgebracht werden.
Applications ferroviaires - Installations fixes - Spécifications particulières pour appareillage à courant alternatif - Partie 1: Disjoncteurs monophasés avec Un supérieur à 1 kV
La présente norme EN 50152 1 est applicable aux disjoncteurs unipolaires monophasés à courant alternatif conçus pour des installations fixes intérieures ou extérieures pour utilisation à des fréquences de 16,7 Hz et 50 Hz dans les réseaux de traction dont la tension UNm est comprise entre 1 kV et 52 kV. La présente norme EN 50152-1 est aussi applicable aux disjoncteurs bipolaires quand ils sont connectés de la façon suivante: un pôle assure la connexion à la caténaire de la voie, l'autre est relié au câble feeder qui court le long de la même voie et qui est utilisé pour surélever la tension de la voie à intervalles réguliers en association avec les autotransformateurs. Le point central de ce circuit est relié à la terre. La présente Norme Européenne est également applicable aux dispositifs de commande des disjoncteurs et à leurs équipements auxiliaires. La présente Norme Européenne ne s'applique pas aux disjoncteurs comportant un mécanisme à manœuvre manuelle dépendante. NOTE : Un pouvoir de fermeture assigné en court-circuit ne peut pas être spécifié pour ces disjoncteurs et l'emploi de tels mécanismes peut être inacceptable pour des raisons de sécurité.

This European Standard was approved by CENELEC on 2007-07-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

Foreword
This European Standard was prepared by SC 9XC, Electric supply and earthing systems for public transport
equipment and ancillary apparatus (fixed installations), of Technical Committee CENELEC TC 9X, Electric
and electronic applications for railways.
This European Standard supersedes EN 50152-1:1997 and has been prepared taking into account the
changes that have been made in the high voltage switchgear and controlgear Standards of IEC TC 17 and in
EN 50124-1/A2:2005.
This document is technically equivalent to EN 50152-1:1997 except for the normative references which have
changed and the revised classification of rated insulation voltages according to Table A.2 of
EN 50124-1/A2:2005.
The text of the draft was submitted to the unique acceptance procedure and was approved by CENELEC as
EN 50152-1 on 2007-07-01.
The following dates were fixed:
− latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2008-07-01
− latest date by which the national Standards conflicting
with the EN have to be withdrawn (dow) 2010-07-01
