This part of IEC 60669 applies to manually operated general purpose switches, for a.c. only with a rated voltage not exceeding 440 V and a rated current not exceeding 63 A, intended for household and similar fixed electrical installations, either indoors or outdoors. For switches provided with screwless terminals the rated current is limited to 16 A. Switches covered by this standard are intended for the control in normal use of: – a circuit for a tungsten filament lamp load; or – a circuit for a fluorescent lamp load (including electronic ballast); or – a circuit for a substantially resistive load with a power factor not less than 0,95; or – a monophase circuit for motor load with a rated current up to 10 A and a power factor not less than 0,6; or – a combination of these.
