1 Scope This part of IEC 60669 applies to manually operated general purpose functional switches, for alternating current (AC) only with a rated voltage not exceeding 440 V with 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.
NOTE 1 The rated current is limited to 16 A for switches provided with insulation piercing terminals ( IPT ’s) according to Annex D.
Switches covered by this document are, where applicable, intended for the control in normal use of all of the following loads:
— a circuit for a tungsten filament lamp load;
— a circuit for an externally ballasted lamp load (for example LED, CFL, fluorescent lamp load);
— a circuit for a self ballasted lamp load (for example LEDi or CFLi);
— a circuit for a substantially resistive load with a power factor not less than 0,95;
