These supplementary requirements apply to fuse-links for application in equipment containing
semiconductor devices for circuits of rated voltages up to 1 000 V a.c. or circuits of nominal voltages up
to 1 500 V d.c. and also, in so far as they are applicable, for circuits of higher nominal voltages.
NOTE 1 Such fuse-links 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 fuse-base 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.
