LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Electromagnetic compatibility assessment
for switchgear and controlgear and their assemblies
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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC TR 63216, which is a technical report, has been prepared by subcommittee 121A: Low-
voltage switchgear and controlgear, of IEC technical committee 121: Switchgear and
controlgear and their assemblies for low voltage.
The text of this technical report is based on the following documents:

INTRODUCTION
Low-voltage switchgear and controlgear and their assemblies (hereinafter referred to as
"equipment") compliant with their standards, when installed and used in accordance with
manufacturer's instructions, operate safely and reliably with a good level of immunity and do
not produce interferences in normal operation or reasonably foreseeable faulty conditions.
This document is intended to support discussions within IEC TC 121 and its sub-committees,
and with other TCs/SCs, by explaining electromagnetic compatibility assessment of
equipment and compatibility measures contained in the IEC 60947 series of standards.
Those measures are based on a system approach, depending on the EMC environment in
industrial applications. They include design rules and type tests to ensure the compatibility of
equipment to the intended electromagnetic environment.
The collection of IEC 61000 series is very large and very generic. The intent of this document
is to provide the essential applicable EMC concepts for IEC TC 121 and its sub-committees'
working groups, maintenance teams and project teams.
For this intent, this document defines specific descriptions of the relevant EMC environments
which are derived from the generic ones of IEC 61000 series. In addition, these environments
are consistent with the zones defined by IEC 61131-2.

LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Electromagnetic compatibility assessment
for switchgear and controlgear and their assemblies
1 Scope
The purpose of this document is to define homogeneous categories for the electromagnetic
environments in order to harmonize as far as practicable all general rules and product
standard requirements of electromagnetic compatibility (EMC), applicable to low-voltage
switchgear, controlgear and their assemblies with built-in electronic circuits.
This document also addresses incorporated radiocommunication functions.
The typical application environments for such equipment include the electrical distribution in
infrastructure, commercial and industrial buildings and the control systems of machinery,
including motor-driven systems.
The primary intention of EMC requirements is to ensure the safe and reliable operation of the
equipment, as well as the communication efficiency of the radiocommunication equipment
within their intended environments.

3.1
compatibility level
electromagnetic compatibility level
specified electromagnetic disturbance level used as a reference level for co-ordination in the
setting of emission and immunity limits
Note 1 to entry: By convention, the compatibility level is chosen so that there is only a small probability that it will
be exceeded by the actual disturbance level. However, electromagnetic compatibility is achieved only if emission
and immunity levels are controlled such that, at each location, the disturbance level resulting from the cumulative
emissions is lower than the immunity level for each device, equipment and system situated at this same location.
Note 2 to entry: The compatibility level may be phenomenon, time or location dependent.

4 Classification of the electromagnetic environments
4.1 General
Classification of an electromagnetic environment is based on the electromagnetic phenomena
prevailing at typical locations.
The purpose of a classification system is to identify a limited set of parameters and
associated values, which can be used to determine performance requirements.
Electromagnetic disturbances impact equipment by radiation or by conduction. A useful
concept is to consider a set of ports, as shown in Figure 1, through which the disturbances
enter (or exit) the equipment under evaluation. The nature and degree of disturbing
phenomena depends on the type of port, so that the tables in this report will take this into
consideration.
Electromagnetic radiated disturbances impact on equipment from distant or close sources,
hence the propagation and coupling can be governed by far-field or by near-field
characteristics. Radiated disturbances that couple into the conductors connected to the
equipment, but outside the equipment enclosure, become conducted disturbances.
The enclosure port shown in Figure 1 concerns only the radiated disturbances that enter the
equipment through its housing (either an actual barrier such as a shield, metallic cabinet, etc.,
or a physical barrier with no electromagnetic impact, such as a plastic housing). The
equipment case is normally considered the enclosure port.
The signal port is the point where a cable carrying signals to or from the equipment or
controlling the equipment can be connected. Examples are input/output (I/O) data/control
lines, wired network lines, etc.
The earth port is the point where a cable intended for connection to earth for functional or
safety purposes can be connected.
The power port is the point where a conductor or cable is connected to the equipment carrying
the electrical power (alternating current or direct current) needed for operation. The power
port can be both the input and output power port.

4.2 Emission classification
According to CISPR 11 and CISPR 32, equipment is classified into two classes depending on
their intended use.
Class B equipment is intended to be used in residential areas and in establishments directly
connected to a low-voltage power supply network which supplies buildings used for domestic
purposes. This class is not normally included in IEC 60947 (all parts), and therefore not
addressed in this document.
– 12 – IEC TR 63216:2019 © IEC 2019
Class A equipment is intended to be used in all locations other than those allocated in
residential areas and those directly connected to a low-voltage power supply network which
supplies buildings used for domestic purposes.
NOTE Class A and B are only related to emission phenomena. Environment A in IEC 60947-1 and
IEC 61439-1:2011 corresponds to Environment E-III. Environment B of IEC 60947-1 corresponds to equipment
Class B in CISPR 11.
The manufacturer and/or supplier of equipment shall ensure that the user is informed about
the class of the equipment, either by labelling or by the accompanying documentation. In both
cases the manufacturer/supplier shall explain the meaning of the class in the documentation
accompanying the equipment (see 7.2).
4.3 Environments
The electromagnetic environments are not the same at all locations of a building or of an
industrial plant (see Figure 2). The following definitions of the environments, necessary for
managing their appropriate separation are consistent with those defined in IEC 61131-2 and
the associated generic EMC standards:
Environment E-IV: Power distribution
LV power distribution where the interconnections are running as outdoor cables along with
power cable or next to a high-voltage power station or substation.
Protection is of particular relevance to power systems and to the safety, continuity of service
and security of both substations and power stations. The precision and rapidity of electronic
protection equipment shall not experience degradation of performance as a consequence of
electromagnetic phenomena.
Environment E-III: Industrial
Factory or infrastructure mains distribution isolated from the electrical public network by a
power distribution transformer, primary surge protection and other substantial decoupling
means in order to mitigate severe interference.
Environment E-III is the standard environment for low-voltage switchgear, controlgear and
their assemblies.
EXAMPLE 1 Metalworking, pulp and paper, chemical plants, car production, farm building, high-voltage (HV)
areas of airports.
NOTE 1 Industrial locations can generally be described by the existence of an installation with one or more of the
following characteristics:
• items of equipment installed and connected together and working simultaneously;
• significant amount of electrical power is generated, transmitted and/or consumed;
• frequent switching of heavy inductive or capacitive loads;
• high currents and associated magnetic fields;
• presence of industrial, high-power scientific and medical (ISM) equipment (for example, welding machines).
The electromagnetic environment at an industrial location is predominantly produced by the equipment and
installation present at the location. There are types of industrial locations where some of the electromagnetic
phenomena appear in a more severe degree than in other installations.
Environment E-II: Light-industrial
Dedicated power distribution separated from factory mains by a dedicated LV/LV transformer,
secondary surge protection, dedicated DC power network, and other decoupling means, in
order to mitigate moderate interference by means of:
IEC TR 63216:2019 © IEC 2019 – 13 –
– shielding and filtering, or
– proper integration within the metallic frame of machinery.
EXAMPLE 2 Light-industrial locations are workshops, laboratories, service centres, control systems of machinery,
offices.
NOTE 2 Environment E-II covers zone A and zone B of IEC 61131-2.
NOTE 3 The term “light-industrial” is related to the EMC environment and not the duty of the equipment, such as
high operating demand or the ability to withstand shocks and vibrations.
Environment E-I: Protected zone
Environment E-I levels apply where installation practices reduce industrial environmental
levels below those of environment E-II. These may be installation of protection networks,
AC/DC converters, isolation transformers, surge suppressers, I/O impedance limiting, shorter
wiring, well-protected power supplies, EMC enclosures, feedthrough filters, etc.
The design of Environment E-I needs a high degree of investigation by selecting appropriate
shielding, filters and often needs measurement and calculation (impedances along the
spectrum, propagation, attenuation, etc.). Therefore, this environment is currently not covered
by EMC standards and product standards.
EXAMPLE 3 A protected zone can be a subassembly supplied by an additional AC/DC power supply installed
within an EMC enclosure.

Residential and commercial EMC areas
Switchgear and controlgear, primarily intended for use in industry, may also be used in
residential and commercial applications directly connected to a low-voltage power supply
network. For these applications, no additional immunity tests are required because their
product standards already require the minimum levels derived from the generic standards
IEC 61000-6-1 or IEC 61000-6-2. But t
