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.

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 connec
