Cable trunking systems and cable ducting systems for electrical installations - Part 2-3: Particular requirements for slotted cable trunking systems intended for installation in cabinets
This European Standard specifies requirements and tests for cable trunking systems (CTS) and cable ducting systems (CDS) intended for the accommodation, and where necessary for the electrically protective separation, of insulated conductors, cables and possibly other electrical equipment in electrical and/or communication systems installations. The maximum voltage of these installations is 1 000 V a.c. and 1 500 V d.c. Slotted cable trunking systems are intended for mounting inside cabinets in electrical and/or communication system installations. This European Standard does not apply to conduit systems, cable tray systems, cable ladder systems, power track systems or equipment covered by other standards. This European Standard shall be used in conjunction with EN 50085-1:2005 “Cable trunking systems and cable ducting systems for electrical installations – Part 1: General requirements” which is referred to in this document as Part 1. Wherever reference is made in this European Standard to EN 50085 1:2005 this does not apply to cable ducting systems.

Sistemi kabelskih korit in sistemi kabelskih cevi za električne inštalacije - 2-3. del: Posebne zahteve za utorske sisteme kabelskih korit za inštalacije v priključnih omaricah
Ta evropski standard določa zahteve in preskuse za sisteme kabelskih korit (CTS) in sisteme kabelskih cevi (CDS), ki so namenjeni za namestitev in po potrebi za električno zaščitno ločevanje izoliranih prevodnikov, kablov in morebiti druge električne opreme v inštalacijah električnih in/ali komunikacijskih sistemov. Največja napetost teh inštalacij je 1 000 V izmeničnega toka in 1 500 V enosmernega toka. Utorski sistemi kabelskih korit so namenjeni za namestitev v priključne omarice v inštalacijah električnih in/ali komunikacijskih sistemov. Ta evropski standard ne velja za sisteme napeljav, sisteme kabelskih polic, sisteme kabelskih lestev, tirne sisteme za električno napeljavo ali opremo, ki jo zajemajo drugi standardi. Ta evropski standard se uporablja v povezavi z EN 50085-1:2005 »Sistemi kabelskih korit in sistemi kabelskih cevi za električne inštalacije – prvi del: Splošne zahteve«, ki ga ta dokument imenuje prvi del. Kadar koli se ta evropski standard sklicuje na EN 50085-1:2005, to ne velja za sisteme kabelskih cevi.

Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 213, Cable
management systems. It was submitted to the formal vote and was approved by CENELEC as
EN 50085-2-3 on 2010-03-01.
This document supersedes EN 50085-2-3:1999 and is aligned on EN 50085-1:2005.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
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

– latest date by which the national standards conflicting
with the EN have to be withdrawn
(dow) 2013-03-01
This European Standard is a system standard for cable management products used for electro-technical
purposes. It relates to the Council Directive on the approximation of laws, regulations and administrative
provisions of the Member States relating to Low Voltage (Directive 2006/95/EC) through consideration of
the essential requirements of this directive.
This European Standard is supported by separate standards to which references are made.
This Part 2-3 is to be used in conjunction with EN 50085-1:2005, “Cable trunking systems and cable
ducting systems for electrical installations – Part 1: General requirements”.
This Part 2-3 supplements or modifies the corresponding clauses of EN 50085-1:2005. Where a particular
clause or subclause of Part 1 is not mentioned in this Part 2, that clause or subclause applies as far as it
