EN 50205:2002

Relays with forcibly guided (mechanically linked) contacts

This European Standard specifies special requirements and tests for elementary relays with forcibly guided contacts, also known as mechanically linked contacts. These special requirements apply in addition to the general requirements of EN 61810-1, EN 61810-5, EN 116000-3 and EN 60255-23. NOTE 1 This standard does not apply to electromechanical control circuit devices as described in IEC/EN 60947-5-1. NOTE 2 EN 116000-3 is nearly equivalent to IEC 61810-7.

Relais mit (mechanisch) zwangsgeführten Kontakten

Diese Europäische Norm legt besondere Anforderungen an und Prüfungen für Elementarrelais mit zwangsgeführten Kontakten fest, die auch als mechanisch verbundene Kontakte bezeichnet werden. Diese besonderen Anforderungen gelten zusätzlich zu den allgemeinen Anforderungen von EN 61810 1, EN 61810 5, EN 116000 3 und EN 60255 23. ANMERKUNG 1 Diese Norm gilt nicht für elektromechanische Steuerschaltungen, wie sie in IEC/EN 60947 5 1 beschrieben sind. ANMERKUNG 2 EN 116000 3 entspricht in weitgehendem Maße IEC 61810 7.

Relais de tout ou rien à contacts guidés (liés)

Cette Norme européenne spécifie les dispositions et essais spéciaux pour les relais élémentaires à contacts guidés, aussi connus comme contacts liés mécaniquement. Ces dispositions spéciales s'appliquent en plus des dispositions générales de l'EN 61810-1, l'EN 61810-5, l'EN 116000-3 et l'EN 60255-23. NOTE 1 Cette norme ne s'applique pas aux appareils électromécaniques pour circuits de commande comme décrits dans la CEI/EN 60947-5-1. NOTE 2 L'EN 116000-3 est pratiquement équivalente à la CEI 61810-7.

This European Standard was approved by CENELEC on 2002-05-01. 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.

Foreword
Following a request from the UK National Committee, the Technical Committee CENELEC
TC 94, Relays, decided to revise the standard EN 50205 and prepare a second edition.
This approach was endorsed by CENELEC Technical Board.
The text of the draft was submitted to the Unique Acceptance Procedure and was
approved by CENELEC as EN 50205 on 2002-05-01.
This European Standard supersedes EN 50205:1997.
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) 2003-05-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2005-05-01
The contents of the standard has been amended by TC 94 in a way to
- improve the wording for better readability,
- improve the structure of the document,
- take into account other recently published standards.

Introduction
This Standard applies to elementary relays in which special design and constructional
measures are used to ensure that make (normally-open) contacts can not assume the
same state as break (normally-closed) contacts. These relays can be used in self-
monitoring control systems, e.g. safety-related control systems.
1 Scope
This European Standard specifies special requirements and tests for elementary relays
with forcibly guided contacts, also known as mechanically linked contacts. These
special requirements apply in addition to the general requirements of EN 61810-1,
EN 61810-5, EN 116000-3 and EN 60255-23.
NOTE 1  This standard does not apply to electromechanical control circuit devices as described in
IEC/EN 60947-5-1.
NOTE 2  EN 116000-3 is nearly equivalent to IEC 61810-7.
2 Normative references
This European Standard incorporates, by dated or undated reference, provisions from
other publications. These normative references are cited at the appropriate places in
the text and the publications are listed hereafter. For dated references, subsequent
