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 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 61000-3-2 has been prepared by sub-committee 77A: Low-frequency
phenomena, of IEC technical committee 77: Electromagnetic compatibility.
This third edition of IEC 61000-3-2 cancels and replaces the second edition published in 2000,
its amendment 1 (2001) and amendment 2 (2004).

Part 3-2: Limits –
Limits for harmonic current emissions
(equipment input current ≤16 A per phase)



1 Scope
This part of IEC 61000 deals with the limitation of harmonic currents injected into the public
supply system.
It specifies limits of harmonic components of the input current which may be produced by
equipment tested under specified conditions.
Harmonic components are measured according to Annexes A and B.
This part of IEC 61000 is applicable to electrical and electronic equipment having an input
current up to and including 16 A per phase, and intended to be connected to public low-voltage
distribution systems.
Arc welding equipment which is not professional equipment, with input current up to and
including 16 A per phase, is included in this standard.
Arc welding equipment intended for professional use, as specified in IEC 60974-1, is excluded
from this standard and may be subject to installation restrictions as indicated in IEC 61000-3-4
or IEC 61000-3-12.
The tests according to this standard are type tests. Test conditions for particular equipment are
given in Annex C.
For systems with nominal voltages less than 220 V (line-to-neutral), the limits have not yet
been considered.
NOTE The words apparatus, appliance, device and equipment are used throughout this standard. They have the
same meaning for the purpose of this standard.

4 General
The objective of this standard is to set limits for harmonic emissions of equipment within its
scope, so that, with due allowance for the emissions from other equipment, compliance with
the limits ensures that harmonic disturbance levels do not exceed the compatibility levels
defined in IEC 61000-2-2.
Professional equipment that does not comply with the requirements of this standard may be
permitted to be connected to certain types of low voltage supplies, if the instruction manual
contains a requirement to ask the supply utility for permission to connect. Recommendations
concerning this aspect are contained in IEC/TS 61000-3-4 or IEC 61000-3-12.
5 Classification of equipment
For the purpose of harmonic current limitation, equipment is classified as follows:
Class A:
– balanced three-phase equipment;
– household appliances, excluding equipment identified as class D;
– tools, excluding portable tools;
– dimmers for incandescent lamps;
– audio equipment.
Equipment not specified in one of the three other classes shall be considered as class A
equipment.
NOTE 1 Equipment that can be shown to have a significant effect on the supply system may be reclassified in a
future edition of the standard. Factors to be taken into account
