These supplementary requirements apply to fuse-links for application in equipment containing
semiconductor devices for circuits of nominal voltages up to 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.
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
