UNE-EN 60669-1:2018

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, 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 (e.g. LED, CFL, fluorescent lamp load);

- a circuit for a self ballasted lamp load (e.g. 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 up to 10 A and a power factor not less than 0,6;

NOTE 1 An increase of the rated current of 10 A for motor load is under consideration.

NOTE 2 Switches with a rated current more than 10 A are considered as a 10 A current for motor load switch.

NOTE 3 Switches with a rated current up to and including 10 A are suitable for single-phase motor loads not exceeding the rated current of the switch and a power factor not less than 0,6.

The standard also applies to boxes for switches, with the exception of mounting boxes for flush type switches.

NOTE 4 General requirements for boxes for 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)

Switches complying with this standard are suitable for use at ambient temperatures not normally exceeding + 40 ºC, but their average over a period of 24 h does not exceed + 35 °C, with a lower limit of the ambient air temperature of 5 °C.

Switches complying with this standard are suitable only for incorporation in equipment in such a way and in such a place that it is unlikely that the surrounding ambient temperature exceeds + 35 °C.

In locations where special conditions prevail, such as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special constructions may be required.
