This part of EN 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.<\/p>\n
For switches provided with screwless terminals the rated current is limited to 16 A.<\/p>\n
Switches covered by this standard are intended for the control in normal use of e.g.:<\/p>\n
a circuit for a tungsten filament lamp load, or<\/p>\n<\/li>\n
a circuit for a fluorescent lamp load (including electronic ballast), or<\/p>\n<\/li>\n
a circuit for a substantially resistive load with a power factor not less than 0,95, or<\/p>\n<\/li>\n
a monophase circuit for motor load with a rated current up to 10 A and a power factor not less than 0,6, or<\/p>\n<\/li>\n
a circuit for extra low voltage (ELV) tungsten halogen lamp load with electronic convertor or magnetic transformer, or<\/p>\n<\/li>\n
a combination of these.<\/p>\n<\/li>\n<\/ul>\n
\nNOTE 1 An extension of the scope to switches for rated voltages higher than 440 V is under consideration. Unless otherwise specified in subsequent parts, this standard applies to switches intended to be used at 50 Hz.<\/p>\n
NOTE 2 Switches according to Part 2-4 are intended for isolating purposes. All other switches according to EN 60669 series are intended for functional purposes only.<\/p>\n
NOTE 3 An increase of the rated current of 10 A for motor load is under consideration.<\/p>\n
NOTE 4 For the time being, switches with a rated current more than 10 A are considered as a 10 A current for motor load switch.<\/p>\n
NOTE 5 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.<\/p>\n
The standard also applies to boxes for switches, with the exception of mounting boxes for flush type switches.<\/p>\n
NOTE 6 General requirements for boxes for flush-type switches are given in EN 60670-1.<\/p>\n<\/blockquote>\n
It also applies to switches such as:<\/p>\n
\n
- \n
switches incorporating pilot lights;<\/p>\n<\/li>\n
- \n
electromagnetic remote control switches (particular requirements are given in the relevant Part 2);<\/p>\n<\/li>\n
- \n
switches incorporating a time-delay device (particular requirements are given in the relevant Part 2);<\/p>\n<\/li>\n
- \n
combinations of switches and other functions (with the exception of switches combined with fuses);<\/p>\n<\/li>\n
- \n
electronic switches (particular requirements are given in the relevant Part 2);<\/p>\n<\/li>\n
- \n
switches having facilities for the outlet and retention of flexible cables (see Annex B);<\/p>\n<\/li>\n
- \n
isolating switches (particular requirements are given in the relevant Part 2).<\/p>\n<\/li>\n<\/ul>\n
\nNOTE 7 The minimum length of the flexible cable used with these switches may be governed by National Wiring Rules.<\/p>\n
Switches complying with this standard are suitable for use at ambient temperatures not normally exceeding 25 \u00b0C, but occasionally reaching 35 \u00b0C.<\/p>\n
NOTE 8 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 \u00b0C.<\/p>\n<\/blockquote>\n
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.<\/p>\n","protected":false},"excerpt":{"rendered":"
