Frequently Asked Questions

MT 9 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 32/SC 32B/MT 9". This committee has published 69 standards.

MT 9 develops IEC standards in the area of Information technology. Currently, there are 69 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.

Low-voltage fuses - Part 4: Supplementary requirements for fuse-links for the protection of semiconductor devices

IEC 60269-4:2024 applies with the following supplementary requirements. Fuse-links for the protection of semiconductor devices shall comply with aIl requirements of IEC 60269-1, if not otherwise indicated hereinafter, and shall also comply with the supplementary requirements laid down below. These supplementary requirements apply to fuse-links for application in equipment containing semiconductor devices for circuits of nominal voltages up to 1 000 V AC or 1 500 V DC. For some fuse‑links higher rated voltages can be used.

Low-voltage fuses - Part 4: Supplementary requirements for fuse-links for the protection of semiconductor devices

IEC 60269-4:2009 is to be used in conjunction with IEC 60269-1. This Part 4 supplements or modifies the corresonding clauses or subclauses of Part 1. Fuse-links for the protection of semiconductor devices shall comply with aIl requirements of IEC 60269-1, if not otherwise indicated hereinafter, and shall also comply with the supplementary requirements laid down below. This fifth edition cancels and replaces the fourth edition published in 2006. It constitutes a technical revision. The significant technical changes to the fourth edition are:
- the introduction of voltage source inverter fuse-links, including test requirements;
- coverage of the tests on operating characteristics for a.c. by the breaking capacity tests;
- the updating of examples of standardised fuse-links for the protection of semiconductor devices.
