Scope of standard This International Standard 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. (between phases) with rated operational currents less than or equal to 63 A for utilization category AC-7a and 32 A for utilization categories AC-7b and AC-7c, and rated conditional short-circuit current less than or equal to 6 kA. The contactors dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 9.3.4) shall form part of the installation. This standard does not apply to – contactors complying with IEC 60947-4-1; – semiconductor contactors; – contactors designed for special applications; – auxiliary contacts of contactors. These are dealt with in IEC 60947-5-1.
