Low-voltage fuses. Part 1: General requirements (IEC 60269-1:2024)

Alkalmazási terület

This part of IEC 60269 is applicable to fuses incorporating enclosed current-limiting fuse-links with rated breaking capacities of not less than 6 kA, intended for protecting power-frequency AC circuits of nominal voltages not exceeding 1 000 V or DC circuits of nominal voltages not exceeding 1 500 V. Subsequent parts of this standard, referred to herein, cover supplementary requirements for such fuses intended for specific conditions of use or applications. Fuse-links intended to be included in fuse-switch combinations according to IEC 60947-3 should also comply with the following requirements. As far as not stated in subsequent parts for fuse-links, details of performance (see 3.2.4) on DC circuits should be stated in the manufacturer's literature. NOTE 1 Modifications of, and supplements to, this document required for certain types of fuses for particular applications – for example, certain fuses for rolling stock, or fuses for high-frequency circuits – will be covered, if necessary, by separate standards. NOTE 2 This document does not apply to miniature fuses, these being covered by IEC 60127. The object of this standard series is to establish the characteristics of fuses or parts of fuses (fuse-base, fuse-carrier, fuse-link) in such a way that they can be replaced by other fuses or parts of fuses having the same characteristics provided that they are interchangeable as far as their dimensions are concerned. For this purpose, this standard series refers in particular to – the following characteristics of fuses: - rated values; - insulation; - temperature rise in normal service; - power dissipation and acceptable power dissipation; - time/current characteristics; - breaking capacity; - cut-off current characteristics and their I2t characteristics. – type test for verification of the characteristics of fuses; – the marking of fuses.
