SR EN IEC 60269-4:2025

These supplementary requirements apply to fuse-links for application in equipment containing semiconductor devices for circuits of nominal voltages up to 1 000 V AC. or 1 500 V DC. 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 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. NOTE 3 IEC 60269-6 (Low-voltage fuses – Part 6: Supplementary requirements for fuse-links for the protection of solar photovoltaic energy systems) is dedicated to the protection of solar photovoltaic energy systems. NOTE 4 These fuse-links are intended for use on systems employing the standardized voltages and tolerances of
