GENERAL REQUIREMENTS FOR ARC FAULT DETECTION AND
PROTECTION DEVICES (AFDDs)
AMENDMENT 2
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 document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 2 to IEC 62606:2013 has been prepared by subcommittee 23E: Circuit-breakers
and similar equipment for household use, of IEC technical committee 23: Electrical accessories.
The text of this Amendment is based on the following documents:

9.9.2 Series arc fault tests
9.9.2.1 General
Replace the existing text of Subclause 9.9.2.1 (as modified by IEC 62606:2013/AMD1:2017)
with the following new text:
An AFDD shall clear the arcing fault in the time specified in Table 1 or Table 2 for the arc current
level being tested. AFDDs shall be tested up to their rated current.
---------------------- Page: 12 ----------------------
IEC 62606:2013/AMD2:2022 – 11 –
IEC 2022
The AFDD being supplied with all phases and neutral (if any), the tests shall be performed, if
applicable, between one phase, chosen at random and neutral, and between two phases chosen
at random.
The tests shall be conducted by connecting a cable specimen (prepared in accordance with
9.9.2.6) in series with the AFDD according to Figure 4 for tests of 9.9.2.2 to 9.9.2.5 and
according to Figure 38 for tests of 9.9.2.8 and 9.9.2.9.
The adjustment of the test currents without arcing, in the line where the cable specimen is
placed, is achieved by application of the line to neutral voltage reduced by 50 V to take into
account the value of the arc voltage during the test. For two-pole AFDDs rated 400 V the
adjustment of the test current without arcing is achieved by application of the line to line voltage
reduced by 50 V. For three-pole AFDDs, and for the adjustment of the test current only, the
mid-point of the resistors in Figure 38 shall be connected directly to the neutral. For tests of
9.9.2.2, and at the rated current only, the adjustment of the test current in the cable specimen
without arcing is achieved by application of the rated voltage.
The break time is measured at each arc current level and the measured value shall not exceed
the times specified in Table 1 or Table 2.
When the break time exceeds the times specified in Table 1 or Table 2 because the arc is not
persistent during this test, the test shall be repeated.
An arc is considered as not persistent if during at least 2 cycles, not necessarily consecutive,
the arc peak current is less than 1.5 A or the arc peak voltage is less than 10 V.
NOTE One cycle is 20 ms for 50 Hz.

9.9.2.8 Verification of correct operation in case of arc in a three-phase system with
unbalanced load
Replace the existing text of the second paragraph of 9.9.2.8 (as modified by
IEC 62606:2013/AMD1:2017), with the following new text:
The detection test shall be performed for each phase. Whatever the rated current value, the
current in the three phases shall be adjusted at 2,5 A, 5 A and the rated current (see Figure 38),
by application of the rated line to neutral voltage reduced by 50 V for all phases, deviating from
the adjustment requirements in 9.9.2.1. The arc test shall then be performed on each phase, in
turn, at the rated voltage and at the previously adjusted current.
9.9.3 Parallel arc fault tests
9.9.3.1 Verification of correct operation in case of parallel arc with limited current
Replace the existing text of the fourth paragraph of 9.9.3.1 with the following new text:
The AFDD being supplied with all phases and neutral (if any), the tests shall be performed, if
applicable, between one phase (chosen at random) and neutral, and between two phases
(chosen at random).
