Low-voltage switchgear and controlgear - Part 7-4: Ancillary equipment - PCB terminal blocks for copper conductors

This part of IEC 60947 specifies requirements for PCB terminal blocks primarily intended for industrial or similar use. Mounting and fixing on the printed circuit board is made by soldering, press-in or equivalent methods to provide electrical and mechanical connection between copper conductors and the printed circuit board. This standard applies to PCB terminal blocks intended to connect copper conductors, with or without special preparation, having a cross-section between 0,05 mm2 and 300 mm2 (AWG 30/600 kcmil), intended to be used in circuits of a rated voltage not exceeding 1000 V a.c. up to 1000 Hz or 1500 V d.c.

Appareillage à basse tension - Partie 7-4: Matériels accessoires - Blocs de jonction pour cartes de circuits imprimés pour conducteurs en cuivre

La CEI 60947-7-4:2013 spécifie les exigences concernant les blocs de jonction pour cartes de circuits imprimés destinés principalement à un usage industriel ou similaire. Le montage et la fixation sur la carte de circuits imprimés s'effectuent par brasage, insertion à force ou par des méthodes équivalentes afin d'assurer une connexion électrique et mécanique entre les conducteurs en cuivre et la carte de circuits imprimés. La présente norme s'applique aux blocs de jonction pour cartes de circuits imprimés destinés à connecter les conducteurs en cuivre, avec ou sans préparation spéciale, dont la section est comprise entre 0,05 mm² et 300 mm² (AWG 30/600 kcmil), destinés à être utilisés dans les circuits dont la tension assignée ne dépasse pas 1 000 V en courant alternatif jusqu'à 1 000 Hz ou 1 500 V en courant continu au maximum.

Ta del standarda IEC 60947 navaja zahteve za priključne bloke na tiskanih vezjih, ki so prvotno namenjeni za industrijsko ali podobno uporabo. Nameščanje in pritrjevanje na tiskana vezja se izvaja s spajkanjem, tiskanjem ali ekvivalentnimi metodami, da se zagotovi električni in mehanski stik med bakrenimi vodniki in tiskanim vezjem. Ta standard velja za priključne bloke na tiskanih vezjih za povezovanje bakrenih vodnikov, s posebno pripravo ali brez nje, s prerezom med 0,05 mm2 in 300 mm2 (AWG 30/600 kcmil), namenjene za uporabo v tokokrogih, katerih nazivna napetost ne presega 1000 V izmenične napetosti s frekvenco do 1000 Hz ali 1500 V enosmerne napetosti.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60947-7-4 has been prepared by subcommittee 17B: Low-voltage
switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear.
The text of this standard is based on the following documents:

INTRODUCTION
This standard IEC 60947-7-4 for PCB terminal blocks covers not only the terminal block
requirements according to IEC 60947-7 series but also takes into account the specifications of
connectors according to IEC 61984 as the requirements for both components are highly
similar due to equivalent applications.

Part 7-4: Ancillary equipment –
PCB terminal blocks for copper conductors



1 General
1.1 Scope
This part of IEC 60947 specifies requirements for PCB terminal blocks primarily intended for
industrial or similar use.
Mounting and fixing on the printed circuit board is made by soldering, press-in or equivalent
methods to provide electrical and mechanical connection between copper conductors and the
printed circuit board.
This standard applies to PCB terminal blocks intended to connect copper conductors, with or
2 2
without special preparation, having a cross-section between 0,05 mm and 300 mm (AWG
30/600 kcmil), intended to be used in circuits of a rated voltage not exceeding 1 000 V a.c. up
to 1 000 Hz or 1 500 V d.c.
NOTE 1 Large cross section terminal blocks are dedicated to specific design of high current PCBs. The range up
to 300 mm² is kept to cover any possible application. Examples of high current PCBs and PCB terminal blocks are
shown in Annex C.
NOTE 2 AWG is the abbreviation of “American Wire Gage” (Gage (US) = Gauge (UK));
kcmil = 1 000 cmil;
1 cmil = 1 circular mil = surface of a circle having a diameter of 1 mil;
1 mil = 1/1 000 inch.
This standard may be used as a guide for special types of PCB terminal blocks with
components, such as disconnect units, integrated cartridge fuse-links and the like.
If applicable, in this standard the term “clamping unit” is used instead of “terminal”. This is
taken into account in case of references to IEC 60947-1.
1.2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.
