Recommendations for dimensional co-ordination between enclosures and built-in devices for rail fixing for household and similar installations

The purpose of this report is to give recommendations of the co-ordination of dimensions between enclosures and built-in devices for rail fixing for household or similar installations by listing the principal overall and related mounting dimensions, the rated current of a single device not exceeding 125 A. Examples of these devices are: MCBs, RCDs switches, fuse-systems, indicating lamps, relays, socket-outlets, timing switches, etc. Compliance with this document does not preclude the need for compliance with other relevant specifications. This document needs not apply to type tested and partially type tested assemblies which are covered by other specifications. The means of fixing envisaged in this document are mounting rails. Other possible means of fixing may be used but are not covered by these recommendations. NOTE The only criterion chosen in this document for co-ordination of dimensions has been the geometry of the devices. When selecting the enclosure, other criteria should be taken into account, e.g. the rated current of the devices.

Priporočila za dimenzijsko usklajevanje razdelilnikov z vgradnimi zaščitnimi napravami za montažo na nosilec za inštalacije v zgradbah

Namen tega poročila je, da navede priporočila za dimenzijsko usklajevanje razdelilnikov z vgradnimi zaščitnimi napravami za montažo na nosilec za inštalacije v zgradbah, tako da se napiše seznam osnovne, celotne in sorodne montažne dimenzije, tako da nominalni tok posamezne naprave ne presega 125 A. Takšne naprave so: MCBs, RCDs, stikala, varovalčni-sistemi, signalna svetila, releji, vtičnice, časovna stikala itd. V skladu s tem dokumentom se ne izključuje potreba po sporazumih z ostalimi podobnimi specifikacijami. Temu dokumentu se ni treba sklicevati na preskuševanje vrst in delno preskuševanje vrst montaž, ki so omenjene v ostalih specifikacijah. Načini pritrjevanja planirani v tem dokumentu, so montiranje pregrad. Ostali možni načini pritrjevanja se lahko uporabljajo, ampak niso zajete v ta priporočila. Nadomešča R023-001:1995.

Foreword
Report R023-001:1995 was prepared by the Technical Committee CENELEC TC 23E, Circuit breakers
and similar devices for household and similar applications. It has been drawn up on the basis of the
th th th
decisions taken by TC 23E at their 9 meeting on 8 and 9 November 1994, where the document
CLC/TC23E(Sec)38 and the relevant comments of the National Committees were examined.
This Report was approved by CENELEC on 1995-03-06.
Following BT decision D124/C048 and TC 23E advice, an updated version of R023-001:1995 was
circulated for voting for conversion into a Technical Report in accordance with the Internal Regulations,
Part 2, Subclause 11.4.3.3 and was approved by CENELEC as CLC/TR 50473 on 2006-01-21.
This Technical Report supersedes R023-001:1995.

1 Scope
The purpose of this report is to give recommendations of the co-ordination of dimensions between
enclosures and built-in devices for rail fixing for household or similar installations by listing the principal
overall and related mounting dimensions, the rated current of a single device not exceeding 125 A.
Examples of these devices are: MCBs, RCDs switches, fuse-systems, indicating lamps, relays, socket-
outlets, timing switches, etc.
Compliance with this document does not preclude the need for compliance with other relevant
specifications.
This document needs not apply to type tested and partially type tested assemblies which are covered by
other specifications. The means of fixing envisaged in this document are mounting rails. Other possible
means of fixing may be used but are not covered by these recommendations.
NOTE The only criterion chosen in this document for co-ordination of dimensions has been the geometry of the devices. When
selecting the enclosure, other criteria should be taken into account, e.g. the rated current of the devices.

3 Definitions
For the purpose of this Technical Report the following definitions apply:

4 Mounting rails
The mounting rails used shall be of the 35 mm “Top hat” type according to EN 60715 or an equivalent

NOTE Other types of mounting rails may be used but are not necessarily covered by these recommendations.
Recommendations for dimensional co-ordination of devices designed to be fixed on two mounting rails
are under consideration. Examples are given in Annex A.
