Abstract
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.
