标准摘要
[中文适用范围]： 涵盖用于保护电路免受过电流损害的各类自动开关装置，涉及固定式、可移开式及插件式等多种安装型式。标准内容涵盖了断路器的定义、额定参数、电气特性、机械特性、温升极限以及防护等级等关键指标。此外，还明确了断路器的分断能力测试流程与要求，确保设备在正常及故障条件下的安全可靠运行。该规范为低压断路器产品的设计、制造、检验及用户选择提供了统一的技术依据，有助于提升电气系统的整体安全性与兼容性，促进相关产品的国际化流通与技术交流。 [外文原描述]： States the characteristics of circuit breakers, the conditions with which they shall comply: (operation and behaviour in normal service, operation and behaviour in case of overload and operation and behaviour in case of short-circuit, dielectic properties), tests intended for confirming that these conditions have been met and the methods to be adopted for these tests, and information to be marked on or given with the appartus. The contents of the corrigendum of March 1997 have been included in this copy.
