SIST EN 50152-1:2013/A1:2013
(Amendment)Railway applications - Fixed installations - Particular requirements for alternating current switchgear - Part 1: Circuit-breakers with nominal voltage above 1 kV
Railway applications - Fixed installations - Particular requirements for alternating current switchgear - Part 1: Circuit-breakers with nominal voltage above 1 kV
This EN 50152-1 is applicable to single-pole and two-pole alternating current (a.c.) circuit-breakers which are:
- for indoor or outdoor fixed installations in tractions systems, and
- operated with an a.c. line voltage and frequency as specified in EN 50163.
NOTE 1 EN 50163 specifies the a.c. traction systems 15 kV 16,7 Hz and 25 kV 50 Hz. NOTE 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 EN 50163. Nevertheless phase to phase voltages are sometimes higher e.g. in autotransformer systems. 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 3 It is impossible to specify a rated short-circuit making current for these circuit-breakers and it is likely that such dependent manual operation is not meeting safety considerations.

Železniške naprave - Stabilne naprave električne vleke - Posebne zahteve za stikalne naprave za izmenični tok - 1. del: Tokovni odklopniki za nazivno napetost nad 1 kV
Ta standard EN 50152-1 se uporablja pri tokovnih odklopnikih z enopolnim ali dvopolnim izmeničnim tokom (a.c.), za katere velja:
– uporabljajo se za notranje ali zunanje pričvrščene naprave v vlečnih sistemih in
– uporabljajo izmenični tok linijskega vodnika, kot je navedeno v standardu EN 50163.
OPOMBA 1 Standard EN 50163 določa vlečne sisteme z izmeničnim tokom 15 kV 16,7 Hz in 25 kV 50 Hz. OPOMBA 2 Ker so tiri vlečnih sistemov z izmeničnim tokom ozemljeni in vključeni v pot povratnega toka, bodo vsi vodniki do ozemljitve v mejah toka, ki so določene v standardu EN 50163. Kljub temu so lahko napetosti med vodniki višje kot na primer v sistemih z avtotransformatorji. Ta evropski standard se uporablja tudi za upravljalne naprave za tokovne odklopnike in njihovo zunanjo opremo. Ta evropski standard ne obravnava tokovnih odklopnikov z odvisnimi ročnimi upravljalnimi mehanizmi. OPOMBA 3 Za te tokovne odklopnike je nemogoče določiti naznačeni tok, ki povzroča kratki stik, in je zato verjetno, da tako odvisno ročno opravljanje ne upošteva varnostnih zahtev.

Overview
EN 50152-1:2012/A1:2013 is a CENELEC amendment to the European standard covering railway applications - fixed installations - particular requirements for alternating current switchgear. Part 1 addresses circuit-breakers with nominal voltage above 1 kV used in fixed railway installations. The amendment (A1) was approved on 2013-08-19 and updates the original EN 50152-1:2012 by modifying the rated operating sequence requirements for specific traction-frequency equipment.
Key metadata:
- Title: Railway applications - Fixed installations - Particular requirements for alternating current switchgear - Part 1: Circuit-breakers with nominal voltage above 1 kV
- Reference: EN 50152-1:2012/A1:2013
- Approving body: CENELEC (CLC/TC 9X, CLC/SC 9XC)
- ICS: 29.120.40; 29.280
Key topics and technical requirements
The amendment is concise and focused; main changes include:
- Modification to clause 5.10 “Rated operating sequence” by adding a specific operating sequence:
- O – t”” – CO, where t”” = 5 s for 16.7 Hz circuit-breakers.
- The standard remains targeted at AC switchgear for railway fixed installations and applies to circuit‑breakers with nominal voltage above 1 kV.
- Contains typical normative elements: approval and implementation dates, multilingual official versions (EN/FR/DE), and notes on national adoption and patent rights.
(Only technical changes explicitly indicated in the amendment are reported; the base EN 50152-1:2012 contains the broader set of requirements for design, testing and operation.)
Practical applications and users
This amendment and the underlying standard are relevant to:
- Manufacturers of high-voltage AC circuit‑breakers for railways (design and type-testing).
- Railway electrical engineers and system designers specifying switchgear for traction power systems.
- Procurement teams and compliance officers ensuring products meet CENELEC railway requirements.
- Test laboratories and certification bodies validating rated operating sequences and performance at traction frequencies (notably 16.7 Hz).
- Maintenance and operations teams integrating approved circuit-breakers into fixed installations.
