(Amendment)Low-voltage switchgear and controlgear - Part 4-3: Contactors and motor-starters - AC semiconductor controllers and contactors for non-motor loads
Low-voltage switchgear and controlgear - Part 4-3: Contactors and motor-starters - AC semiconductor controllers and contactors for non-motor loads
EN IEC 60947-4-3 applies to a.c. semiconductor non-motor load controllers and contactors intended for performing electrical operations by changing the state of a.c. electric circuits between the ON-state and the OFF-state. Typical applications are classified by utilization categories given in Table 2. As controllers, they may be used to reduce the amplitude of the r.m.s. a.c. voltage on the load terminals from that of the applied voltage - either continuously or for a specified period of time. The half-wave period of the a.c. wave form remains unchanged from that of the applied voltage. They may include a series mechanical switching device and are intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. This standard characterizes controllers and contactors for use with or without bypass switching devices. The semiconductor controllers and contactors dealt with in this standard are not normally intended to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 8.2.5) should form part of the installation but not necessarily of the controller itself. In this context, this standard gives requirements for semiconductor controllers and contactors associated with separate short-circuit protective devices.

Appareillage à basse tension - Partie 4-3: Contacteurs et démarreurs de moteurs - Gradateurs et contacteurs à semiconducteurs pour charges, autres que des moteurs, à courant alternatif
L'IEC 60947-4-3:2014 s'applique aux gradateurs et démarreurs à semiconducteurs à courant alternatif pour des charges autres que des moteurs prévus pour effectuer des man uvres électriques en changeant l'état des circuits électriques à courant alternatif entre l'état passant et l'état bloqué. Des applications typiques classées par catégorie d'emploi sont données au Tableau 2. Cette deuxième édition annule et remplace la première édition parue en 1999, l'Amendement 1:2006 et l'Amendement 2:2011. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) mise à jour des exigences de marquage (6.1);
b) mise à jour des exigences de CEM (8.3.2); et
c) mise à jour des exigences d'essais (9.3.1, 9.4, 9.4.1.1, 9.4.1.2, 9.4.2.1, 9.4.2.2, 9.4.2.3, 9.4.2.4, 9.4.2.6).
Nizkonapetostne stikalne in krmilne naprave - 4-3. del: Kontaktorji in motorski zaganjalniki, polprevodniški krmilniki in kontaktorji na izmenični tok za nemotorske obremenitve (IEC 60947-4-3:2014)
Standard EN IEC 60947-4-3 se uporablja za polprevodniške krmilnike in kontaktorje na izmenični tok za nemotorske obremenitve, namenjene izvajanju električnih operacij s spreminjanjem stanja izmeničnih električnih tokokrogov med stanjem vključenosti in izključenosti. Običajne uporabe se razvrščajo po kategorijah uporabe iz tabele 2. Kot krmilniki se lahko uporabljajo za zmanjšanje amplitude efektivne izmenične napetosti na bremenskih spojkah glede na amplitudo uporabljene napetosti, in sicer trajno ali za določeno obdobje. Obdobje polovičnega vala izmenične valovne oblike ostaja nespremenjeno glede na obdobje uporabljene napetosti. Vključujejo lahko serijsko mehansko stikalno napravo in so namenjeni priključku na tokokroge z naznačeno izmenično napetostjo, ki ne presega 1000 V. Ta standard opisuje krmilnike in kontaktorje za uporabo z obvodnimi stikalnimi napravami ali brez njih. Polprevodniški krmilniki in kontaktorji, obravnavani v tem standardu, običajno niso namenjeni prekinitvi kratkostičnih tokov. Zato naj bi bila ustrezna zaščita pred kratkim stikom (glej točko 8.2.5) del inštalacije, vendar ne nujno tudi del samega krmilnika. V tem okviru ta standard določa zahteve za polprevodniške krmilnike in kontaktorje, povezane z ločenimi napravami za zaščito pred kratkim stikom.

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 60947-4-3 has been prepared by subcommittee 17B: Low-voltage
switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear.
This second edition cancels and replaces the first edition published in 1999, Amendment
1:2006 and Amendment 2:2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Update of the marking requirements (6.1);
b) Update of the EMC requirements (8.3.2); and
c) Update of the tests requirements (9.3.1, 9.4, 9.4.1.1, 9.4.1.2, 9.4.2.1, 9.4.2.2, 9.4.2.3,
9.4.2.4, 9.4.2.6).
