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

Scope

IEC 60269-4:2009 is to be used in conjunction with IEC 60269-1. This Part 4 supplements or modifies the corresonding clauses or subclauses of Part 1. Fuse-links for the protection of semiconductor devices shall comply with aIl requirements of IEC 60269-1, if not otherwise indicated hereinafter, and shall also comply with the supplementary requirements laid down below. This fifth edition cancels and replaces the fourth edition published in 2006. It constitutes a technical revision. The significant technical changes to the fourth edition are: - the introduction of voltage source inverter fuse-links, including test requirements; - coverage of the tests on operating characteristics for a.c. by the breaking capacity tests; - the updating of examples of standardised fuse-links for the protection of semiconductor devices.
