IEC 60269-4:204适用于以下补充要求。除非下文另有说明，否则用于保护半导体器件的熔断体应符合IEC 60269-1的所有要求，并应符合以下规定的补充要求。这些补充要求适用于标称电压高达1000V AC或1500V DC的电路中包含半导体器件的设备中的熔断器。对于一些保险丝可以使用更高额定电压的链路。

IEC 60269-4:2024 applies with the following supplementary requirements. 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. 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. For some fuse？links higher rated voltages can be used.
