标准摘要
[中文适用范围]: 适用于家用和类似用途的机电空气断路接触器,其主触点用于连接到额定电压不超过 440 V 交流电、额定工作电流小于或等于 63 A 的电路,使用类别为 AC-7a 和使用类别 AC-7b 为 32 A,额定条件短路电流小于或等于 6 kA。该标准取代 IEC 60158-3。该合并版本由第一版(1992 年)及其修正案 1(2000 年)组成。因此,无需对本出版物进行修订。 [外文原描述]: Applies to electromechanical air break contactors for household and similar purposes provided with main contacts intended to be connected to circuits the rated voltage of which does not exceed 440 V a.c. with rated operational currents less than or equal to 63 A for utilization category AC-7a and 32 A for utilization category AC-7b, and rated conditional short-circuit current less than or equal to 6 kA. This standard replaces IEC 60158-3. This consolidated version consists of the first edition (1992) and its amendment 1 (2000). Therefore, no need to order amendment in addition to this publication.
