低压保险丝 第3部分：非熟练人员操作保险丝的补充要求（主要用于家庭和类似用途的保险丝） A 至 F 保险丝标准化系统示例

[中文适用范围]： 本部分包含四个熔断器系统，每个系统针对非熟练人员使用的标准化熔断器提供具体示例。本部分仅适用于"gG"型熔断器。非熟练人员不具备技术知识或充分经验。为避免电力可能造成的危险，相关熔断器标准部分应提供服役中的最高安全要求。IEC 60269-3为非熟练人员提供了四种系统。制造商的文献中提供了熔断器安全操作的说明。所有系统都提供了各自的机械解决方案，以避免使用额定电流更高的熔断器（不可互换性），从而确保线路和电缆的保护。申请人必须注意用同类型熔断器更换熔断体。本部分适用于额定电流最高达100A，额定电压最高达500V交流电和500V直流电，用于家庭和类似应用的非熟练人员使用的"gG"熔断器。 [外文原描述]： IEC 60269-3:2024 is divided into four fuse systems, each dealing with a specific example of standardized fuses for use by unskilled persons. This part applies to “gG” fuses only. Unskilled persons do not have technical knowledge or sufficient experience. To avoid dangers, which electricity may create, the relevant part of the fuse standard shall provide requirements for maximum safety in service. IEC 60269-3 provides four systems for use by unskilled persons. Instructions for the safe operation of fuse-links are provided in the manufacturer’s literature. All systems provide their own mechanical solution to avoid the use of a fuse-link with higher current rating (non-interchangeability) whereas the protection of cables and lines is ensured. The applicant is required to take care to replace a fuse-link by the same type. The content of the corrigendum 1 (2025-11) has been included in this copy.
