IEC/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

This committee has published 45 standards.
IEC/SC 32B develops ISO standards in the area of Information technology. 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 45 published standards from this subcommittee.
The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.
A Subcommittee (SC) in ISO operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.
