适用范围：These supplementary requirements apply to fuse-links for application in equipment containingsemiconductor devices for circuits of nominal voltages up to 1 000 V a.c. or 1 500 V d.c. andalso, in so far as they are applicable, for circuits of higher nominal voltages.NOTE 1 Such fuse-Iinks are commonly referred to as “semiconductor fuse-links”.NOTE 2 In most cases, a part of the associated equipment serves the purpose of a fuse-base. Owing to the great variety of equipment, no general rules can be given; the suitability of the associated equipment to serve as a fusebase should be subject to agreement between the manufacturer and the user. However, if separate fuse-bases or fuse-holders are used, they should comply with the appropriate requirements of IEC 60269-1.The object of these supplementary requirements is to establish the characteristics of semiconductor fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics, provided that their dimensions are identical. For this purpose, this standard refers in particular toa) the following characteristics of fuses:1) their rated values;2) their temperature rises in normal service;3) their power dissipation;4) their time-current characteristics;5) their breaking capacity;6) their cut-off current characteristics and their I2t characteristics;7) their arc voltage characteristics;b) type tests for verification of the characteristics of fuses;c) the markings on fuses;d) availability and presentation of technical data (see Annex B).
