标准摘要
[中文适用范围]: 本国际标准适用于与家用和类似用途的过电流保护断路器以及带或不带内置过电流保护的剩余电流动作断路器(带或不带内置过电流保护)相连接(或打算连接)的机电辅助接触单元,其额定电压不超过交流440V和直流250V,额定电流不超过10A。注1:这些要求也可用作指导,适用于打算与其他家用和类似用途的开关设备组装的辅助接触单元。注2:建议在使用低能量设备(低电流和/或低电压值)时咨询制造商的建议。对于低能量接触,IEC 60947-5-4中给出了具体建议。本标准的目的是规定:a) 辅助接触单元的特性;b) 它们关于以下方面的电气和机械要求:1) 必须执行的各种功能;2) 额定特性和标记的含义;3) 验证额定特性的试验;c) 辅助接触单元必须满足的功能要求,涉及:1) 环境条件,包括封闭设备的条件;2) 介电特性;3) 端子;4) 使用安全。 [外文原描述]: Applies to auxiliary contact units associated (or intended to be associated) with circuit-breakers for overcurrent protection, and with residual current operated circuit-breakers with or without integral overcurrent protection for household and similar installations, having a rated voltage not exceeding 440 V a.c. and 250 V d.c., and a rated current not exceeding 10 A. This consolidated version consists of the first edition (1999) and its amendment 1 (2002). Therefore, no need to order amendment in addition to this publication.
