(Main)Low-voltage fuses - Part 4: Supplementary requirements for fuse-links for the protection of semiconductor devices
Low-voltage fuses - Part 4: Supplementary requirements for fuse-links for the protection of semiconductor devices
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.
