Electromagnetic compatibility (EMC) - Part 3-12: Limits - Limits for harmonic currents produced by equipment connected to public low-voltage systems with input current > 16 A and <= 75 A per phase

Deals with the limitation of harmonic currents injected into the public supply system. The limits given in this International Standard are applicable to electrical and electronic equipment with a rated input current exceeding 16 A and up to and including 75 A per phase, intended to be connected to public low-voltage a.c. distribution systems of the following types: - nominal voltage up to 240 V, single-phase, two or three wires; - nominal voltage up to 690 V, three-phase, three or four wires; - nominal frequency 50 Hz or 60 Hz. Other distribution systems are excluded. The limits given in this edition apply to equipment when connected to 230/400 V, 50 Hz systems. This standard applies to equipment intended to be connected to low-voltage systems interfacing with the public supply at the low-voltage level. It does not apply to equipment intended to be connected only to private low-voltage systems interfacing with the public supply only at the medium- or high-voltage level. This standard defines: a) requirements and emission limits for equipment; b) methods for type tests and simulations. Tests according to this International Standard are type tests of complete pieces of equipment. Conformity with this standard can also be determined by validated simulations.

Compatibilité électromagnétique (CEM) - Partie 3-12: Limites - Limites pour les courants harmoniques produits par les appareils connectés aux réseaux publics basse tension ayant un courant appelé > 16 A et <= 75 A par phase

Traite de la limitation des courants harmoniques injectés dans le réseau public d'alimentation. Les limites définies dans la présente Norme internationale sont applicables aux appareils électriques et électroniques ayant un courant assigné d'entrée supérieur à 16 A et inférieur ou égal à 75 A par phase, destinés à être connectés aux réseaux publics de distribution en courant alternatif basse tension des types suivants: - tension nominale jusqu'à 240 V, monophasé, deux ou trois conducteurs; - tension nominale jusqu'à 690 V, triphasé, trois ou quatre conducteurs; - fréquence nominale 50 Hz ou 60 Hz. Les autres réseaux de distribution sont exclus. Les limites définies dans la présente édition s'appliquent aux appareils connectés aux réseaux 230/400 V, 50 Hz. La présente norme s'applique aux appareils destinés à être raccordés à des réseaux basse tension connectés au réseau public d'alimentation au niveau basse tension. Elle ne s'applique pas aux appareils destinés à être raccordés uniquement à des réseaux basse tension privés connectés au réseau public d'alimentation seulement au niveau moyenne ou haute tension. Cette norme définit: a) les exigences et limites d'émissions pour les appareils; b) les méthodes d'essai de type et de simulation. Les essais réalisés conformément à la présente Norme internationale sont des essais de type sur des équipements complets. La conformité à la présente norme peut également être déterminée au moyen de simulations validées.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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
