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.
This consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
IEC 60127-3 edition 3.1 contains the third edition (2015-01) [documents 32C/501/FDIS
and 32C/506/RVD] and its amendment 1 (2020-07) [documents 32C/586/FDIS and
32C/589/RVD].

International Standard IEC 60127-3 has been prepared by subcommittee 32C: Miniature fuses,
of IEC technical committee 32: Fuses.
This edition includes the following significant technical changes with respect to the previous
edition:
a) add a rectangular shape fuse-link as alternative in standard sheets 3 and 4;
b) add a small cartridge fuse-link as alternative in standard sheets 2, 3 and 4;
c) add the rated currents up to 10A in standard sheets 2, 3 and 4;
d) add Subclause 6.5;
e) add Subclause 9.7;
f) the extra samples for termination test (E1 to E6) will be chosen by random and not sorted
by voltage drop in Table 1, 2, 3, and 4.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This International Standard is to be used in conjunction with IEC 60127-1:2006, Miniature
fuses – Part 1: Definitions for miniature fuses and general requirements for miniature fuse-
links and its Amendment 1 (2011).
The clauses of this standard supplement, modify or replace the corresponding clauses in
IEC 60127-1.
Where there is no corresponding clause or subclause in this standard, the clause or
subclause of IEC 60127-1 applies without modification as far as is reasonable. When this
standard states “addition” or “replacement”, the relevant text in IEC 60127-1 is to be adapted
accordingly.
A list of all parts in the IEC 60127 series, published under the general title Miniature fuses,
can be found on the IEC website.
The committee has decided that the contents of the base publication and its amendment will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

INTRODUCTION
According to the wish expressed by the users of miniature fuses, all standards,
recommendations and other documents relating to miniature fuses should have the same
publication number in order to facilitate reference to fuses in other specifications, for example,
equipment specifications.
Furthermore, a single publication number and subdivision into parts would facilitate the
establishment of new standards, because clauses and subclauses containing general
requirements need not be repeated.
The new IEC 60127 series is thus subdivided as follows:
IEC 60127, Miniature fuses (general title)
IEC 60127-1, Miniature fuses – Part 1: Definitions for miniature fuses and general
requirements for miniature fuse-links
IEC 60127-2, Miniature fuses – Part 2: Cartridge fuse-links
IEC 60127-3, Miniature fuses – Part 3: Sub-miniature fuse-links
IEC 60127-4, Miniature fuses – Part 4: Universal modular fuse-links (UMF) – Through-hole
and surface mount types
IEC 60127-5, Miniature fuses – Part 5: Guidelines for quality assessment of miniature fuse-
links
IEC 60127-6, Miniature fuses – Part 6: Fuse-holders for miniature fuse-links
IEC 60127-7, Miniature fuses – Part 7: Miniature fuse-links for special applications
IEC 60127-8, (Free for further documents)
IEC 60127-9, (Free for further documents)

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.
This consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
IEC 60127-3 edition 3.1 contains the third edition (2015-01) [documents 32C/501/FDIS
and 32C/506/RVD] and its amendment 1 (2020-07) [documents 32C/586/FDIS and
32C/589/RVD].
In this Redline version, a vertical line in the margin shows where the technical content
is modified by amendment 1. Additions are in green text, deletions are in strikethrough
red text. A separate Final version with all changes accepted is available in this
publication.

International Standard IEC 60127-3 has been prepared by subcommittee 32C: Miniature fuses,
of IEC technical committee 32: Fuses.
This edition includes the following significant technical changes with respect to the previous
edition:
a) add a rectangular shape fuse-link as alternative in standard sheets 3 and 4;
b) add a small cartridge fuse-link as alternative in standard sheets 2, 3 and 4;
c) add the rated currents up to 10A in standard sheets 2, 3 and 4;
d) add Subclause 6.5;
e) add Subclause 9.7;
f) the extra samples for termination test (E1 to E6) will be chosen by random and not sorted
by voltage drop in Table 1, 2, 3, and 4.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This International Standard is to be used in conjunction with IEC 60127-1:2006, Miniature
