微型熔断器 第 1 部分：微型熔断器的定义和微型熔断体的一般要求

[中文适用范围]： 本文件规定了适用于所有类型微型熔断器（例如管状熔断器、子微型熔断器、通用模块化熔断器以及用于特殊应用的微型熔断器）的通用要求和测试，用于保护通常用于室内的电 appliances、电子设备及其零部件。本文件不适用于用于保护低压电气装置的熔断器（由IEC 60269涵盖）。本文件也不适用于用于特殊条件（例如腐蚀性或爆炸性气氛）下使用的设备的熔断器。本文件的目标是：a) 建立微型熔断器的统一要求，以最适宜的方式保护设备或设备部件；b) 定义熔断器的性能，为电气设备和电子设备的 designers 提供指导，并确保由尺寸和特性相似的熔断器进行更换；c) 定义测试方法；d) 定义熔断器的最大持续功耗，以确保与根据本文件（见IEC 60127-6）制造的熔断器座具有良好的功率兼容性。 [外文原描述]： IEC 60127-1:2023 covers the general requirements and tests applicable to all types of miniature fuse-links (e.g. cartridge fuse-links, sub-miniature fuse-links, universal modular fuse-links and miniature fuse-links for special applications) for the protection of electric appliances, electronic equipment and component parts thereof normally intended to be used indoors. This document does not apply to fuses intended for the protection of low-voltage electrical installations. These are covered by IEC 60269, Low Voltage Fuses. Specific details covering each major subdivision are given in subsequent parts. This document does not apply to fuses for appliances intended to be used under special conditions, such as in a corrosive or explosive atmos­phere. The object of this document is - to establish uniform requirements for miniature fuses so as to protect appliances or parts of appliances in the most suitable way, - to define the performance of the fuses, so as to give guidance to designers of electrical appliances and electronic equipment and to ensure replacement of fuse-links by those of similar dimensions and characteristics, - to define methods of testing, - to define maximum sustained dissipation of fuse-links to ensure good compatibility of stated power acceptance when used with fuse-holders according to this document (see IEC 60127-6).
