High-voltage fuses -- Part 1: Current-limiting fuses
This part of IEC 60282 applies to all types of high-voltage current-limiting fuses designed for use outdoors or indoors on alternating current systems of 50 Hz and 60 Hz and of rated voltages exceeding 1 000 V. Some fuses are provided with fuse-links equipped with an indicating device or a striker. These fuses come within the scope of this standard, but the correct operation of the striker in combination with the tripping mechanism of the switching device is outside the scope of this standard; see IEC 62271-105.

HIGH-VOLTAGE FUSES –
Part 1: Current-limiting fuses
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 60282-1 has been prepared by subcommittee 32A: High-voltage
fuses, of IEC technical committee 32: Fuses.
This sixth edition cancels and replace the fifth edition published in 2002, and constitutes a
technical revision. The content of the corrigendum (August 2002) has been considered for this
revision.
The main changes introduced by this new edition are as follows:
– definition and dedicated test requirements for so-called "organic fuses";
– definition and requirements for maximum application temperature in order to cover
applications in which the fuses are used in surrounding temperatures above 40 °C;
– clarification and improvements for testing fuses that exhibit a cross-over current;
– information about fuses operated in parallel.

FDIS Report on voting
32A/235/FDIS 32A/238/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The IEC 60282 series consists of the following parts, under the general title High-voltage
fuses:
Part 1: Current-limiting fuses
Part 2: Expulsion fuses
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result 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 either be:
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

Some fuses are provided with fuse-links equipped with an indicating device or a striker. These

2 Normal and special service conditions
2.1 Normal service conditions
Fuses complying with this standard are designed to be used under the following conditions.
a) The maximum ambient air temperature is 40 °C and its mean measured over a period of
24 h does not exceed 35 °C.
The minimum ambient air temperature is –25 °C.
NOTE 1 The time-current characteristics of fuses will be modified at the minimum and maximum
temperatures.
b) The altitude does not exceed 1 000 m (3 300 ft).
NOTE 2 The rated voltages and insulation levels specified in this standard apply to fuses intended for use at
altitudes not exceeding 1 000 m (3 300 ft). When fuses incorporating external insulation are required for use at
altitudes above 1 000 m (3 300 ft), one or other of the following procedures should be adopted.
a) The test voltages for insulating parts in air should be determined by multiplying the standard test voltages
given in Tables 4 and 5 by the appropriate correction factor given in column (2) of Table 1.
b) The fuses may be selected with a rated voltage which, when multiplied by the appropriate correction factor
given in column (3) of Table 1 is not lower than the highest voltage of the system.
For altitudes between 1 000 m (3 300 ft) and 1 500 m (5 000 ft) and between 1 500 m (5
000 ft) and 3 000 m (10 000 ft), the correction factors can be obtained by linear
interpolation between the values in Table 1.

1 500 (5 000) 1,05 0,95
3 000 (10 000) 1,25 0,80
Where the dielectric characteristics are identical at any altitude, no special precautions
need to be taken.
NOTE 3 The rated current or the temperature rise specified in this standard can be corrected for altitudes
exceeding 1000 m (3300 ft) by using the appropriate factors given in Table 2, columns (2) and (3) respectively.
Use one correction factor from columns (2) or (3), but not both, for any one application.
For altitudes between 1 000 m (3 300 ft) and 1 500 m (5 000 ft) and between 1 500 m (5 000 ft) and 3 000 m
(10 000 ft), the correction factors can be obtained by linear interpolation between the values in Tab
