MS IEC 60669-1:2017 Switches for household and similar fixed-electrical installations — Part 1: General requirement

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;

– a single phase circuit for motor load with a rated current not exceeding 3 A at 250 V (750 VA) and 4,5 A at 120 V (540 VA) and a power factor not less than 0,6.

This applies to both switches rated not less than 10 A that have not undergone additional tests and to momentary switches rated not less than 6 A that have not undergone additional tests.
NOTE 2 In the following country the suitability of a switch intended to control the inrush current of a motor shall be tested: AU.
This document also applies to boxes for switches, with the exception of mounting boxes for flush-type switches.

NOTE 3 General requirements for boxes for ordinary flush-type switches are given in IEC 60670-1.

It also applies to switches such as:

– switches incorporating pilot lights;

– electromagnetic remote control switches (particular requirements are given in IEC 60669-2-2);

– switches incorporating a time-delay device (particular requirements are given in IEC 60669-2-3);

– combinations of switches and other functions (with the exception of switches combined
with fuses);

– electronic switches (particular requirements are given in IEC 60669-2-1);

– switches having facilities for the outlet and retention of flexible cables (see Annex A);

– isolating switches (particular requirements are given in IEC 60669-2-4);

– switches and related accessories for use in home and building electronic systems
(particular requirements are given in IEC 60669-2-5);

– firemen’s switches (particular requirements are given in IEC 60669-2-6).
