SC 32B - Low-voltage fuses
To prepare international standards for the following types of fuses intended to be used at nominal voltages not exceeding 1 000 V a.c. or 1 500 V d.c. and also, in so far as they are applicable, for circuits of higher nominal voltages: - fuses for the protection of all types of circuits in electrical installations (e.g. industrial or domestic) against overload and/or short-circuit currents - fuses for the protection of all kinds of systems apparatus or components (e.g. motors, electro-domestic appliances, semiconductor devices) against overload and/or short-circuit currents with a rated breaking capacity of at least 6 000 A a.c. or 2000 A d.c.
Coupe-circuits à fusibles à basse tension
Etablir des normes internationales pour les types suivants de fusibles destinés à être utilisés à des tensions nominales inférieures ou égales à 1 000 V en courant alternatif, ou 1 500 V en courant continu, ainsi que, s?il y a lieu, dans des circuits de tensions nominales supérieures à ces valeurs : - fusibles pour la protection de tous les types de circuits dans les installations électriques (par exemple, industriels ou domestiques) contre la surcharge et / ou les courants de court-circuit - fusibles pour la protection de toutes sortes d'appareils ou de systèmes de composants (par exemple, les moteurs, les appareils électro-domestiques, les dispositifs semi-conducteurs) contre la surcharge et / ou les courants de court-circuit avec un pouvoir de coupure assigné d'au moins 6 000 A c.a ou 2000 A en c.c

SC 32B develops IEC standards. The scope of work includes: To prepare international standards for the following types of fuses intended to be used at nominal voltages not exceeding 1 000 V a.c. or 1 500 V d.c. and also, in so far as they are applicable, for circuits of higher nominal voltages: - fuses for the protection of all types of circuits in electrical installations (e.g. industrial or domestic) against overload and/or short-circuit currents - fuses for the protection of all kinds of systems apparatus or components (e.g. motors, electro-domestic appliances, semiconductor devices) against overload and/or short-circuit currents with a rated breaking capacity of at least 6 000 A a.c. or 2000 A d.c. Currently, there are 50 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.
