标准摘要
[中文适用范围]： 适用于电压不超过 1 000 V 以及 1 000 V 以上的所有装置。描述了旨在确保正常使用和故障情况下人员安全免遭电击的保护措施。此外，还适用于 TN、TT 和 IT 系统接地的特殊要求。将过载和短路保护的原理扩展到过流保护，以及过载和短路保护的配合以及该保护与导体和设备的配合。此外，IEC 364 中制定的导体保护原则也扩展到了装置安全和人员保护方面的设备保护。 [外文原描述]： Applies to all installations with voltages up to and including 1 000 V as well as with those above 1 000 V. Describes protective measures intended to ensure the safety of persons from electric shock in normal service and in case of fault. Also, particular requirements applicable to TN, TT and IT system earthing. Extends the principles to the protection against overcurrent in respect of overload and short-circuit protection, together with the co-ordination of overload and short-circuit protection and the coordination of this protection with the conductors and apparatus. Also, the principles developed in IEC 364 for the protection of conductors are extended to the protection of apparatus in respect of security of the installation and protection of personnel.
