Miniature fuses - Part 1: Definitions for miniature fuses and general requirements for miniature fuse-links

General information

50.60     Jul 28, 2023



European Norm



This part of IEC 60127 covers the general requirements and tests applicable to all types of miniature fuse-links (e.g. cartridge fuse-links, sub-miniature fuse-links, universal modular fuse-links and miniature fuse-links for special applications) for the protection of electric appliances, electronic equipment and component parts thereof normally intended to be used indoors.
This standard does not apply to fuses intended for the protection of low-voltage electrical installations. These are covered by IEC 60269, Low Voltage Fuses.
Specific details covering each major subdivision are given in subsequent parts.
This standard does not apply to fuses for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere.
The object of this standard is
a) to establish uniform requirements for miniature fuses so as to protect appliances or parts of appliances in the most suitable way,
b) to define the performance of the fuses, so as to give guidance to designers of electrical appliances and electronic equipment and to ensure replacement of fuse-links by those of similar dimensions and characteristics,
c) to define methods of testing,
d) to define maximum sustained dissipation of fuse-links to ensure good compatibility of stated power acceptance when used with fuse-holders according to this standard (see IEC 60127-6).
