Frequently Asked Questions
MT 3 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 32/SC 32A/MT 3". This committee has published 85 standards.
MT 3 develops IEC standards in the area of Information technology. Currently, there are 85 published standards from this technical committee.
The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
IEC 60282-1:2020 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.
This eighth edition cancels and replaces the seventh edition published in 2009.
This edition includes the following significant technical changes with respect to the previous edition:
– additional information concerning thermally operated strikers;
– the division of ratings, characteristics and type tests into those applicable to all fuses and those applicable to particular fuse-link types and applications;
– adjustment of Series II voltages and tests to meet present North American standard system voltages and applications;
– clarification of requirements for fuse-links used in surrounding temperatures above 40 °C; and
– clarification of homogeneous requirements for fuse-links containing one element.

IEC 60644:2009 applies primarily to fuse-links used with motors started direct-on-line on alternating current systems of 50 Hz and 60 Hz. Standardizes time-current characteristics to formulate additional pulse withstand requirements regarding testing and to give guidance for the selection of fuse-links to be used with motors. Note: Fuse-links according to this specification should comply with the requirements of IEC 60282-1. The main changes with regard to the previous edition concern the following:
- update of the normative references;
- renewal of the figures.

The object of this Technical Report is to specify criteria for coordination of high-voltage fuses with other circuit components in transformer applications and to give guidance for the selection of fuse-links with particular reference to their time-current characteristics and ratings. This technical report cancels and replaces International Standard IEC 60787, published in 1983, and constitutes a technical revision.
