IEC 60570 pdf download Electrical supply track systems for luminaires
This International Standard applies to the following track systems with two or more poles forthe connection of luminaires to the electrical supply consisting of,either
– a system with a rated voltage not exceeding 440 v between poles (live conductors) with
provision for earthing (class l) and a rated current not exceeding 16 A per conductor, or- a SELv system with a rated voltage not exceeding 25 V without provision for earthing(class lll) and a rated current not exceeding 25 A per conductor, or
a combination of the two systems mentioned above (mixed supply system) for theconnection of both mains voltage luminaires (class l or ll) and sELV supplied luminaires(class lll) simultaneously, but in different sector openings (mains or SELV).
The track systems may also provide for the mechanical support of the luminaires.
lt applies to track systems designed for ordinary interior use for mounting on,or flush with, orsuspended from walls and ceilings. These track systems are not intended for locations wherespecial conditions prevail as in ships,vehicles and the like and in hazardous locations,for example, where explosions are liable to occur.

3 Terms and definitions
For the purposes of this standard, the definitions of section one of lIEC 60598-1 apply, togetherwith the following definitions.
NOTEThe use of the term luminaire (see lEC 60598-1) hereinafter also includes components of the luminairetrack system.
luminaire track system
system,including a track with conductors,for the connection of luminaires to an electricalsupply in a range of different positions determined only by the length and location of the trackand comprising some or all of the components defined in 3.2 to 3.14(see also Figure 1)
generally linear assembly of conductors within a housing providing the electrical connectionand in most instances mechanical support of luminaires
NOTELuminaires can be positioned or repositioned along the length of track in a simple manner (that is, withoutthe use of tools).
track* coupler
component enabling electrical or mechanical connection to be made between tracks, butelectrically only on the same sector opening (mains voltage or SELV)
track* supply connector
component used for the electrical connection of a supply to the track system, but alwaysoperating on one sector opening only
NOTE 1 The function of a coupler and a track supply connector may be combined.
NOTE 2 For the SELV sector, the track supply connector may incorporate a SELV convertor or safety isolatingtransformer supplied directly from the mains voltage sector.
luminaire supply connector
component for the electrical connection of a luminaire to the track.A connector does notprovide mechanical connection of a luminaire to the track
The electrical connection shall operate on one sector only (mains or SELV)
track” adaptor
component used for the electrical and mechanical connection of a luminaire to the track, butelectrically and mechanically only on the same sector opening (mains voltage or SELV)
NOTE An adaptor may incorporate a switch or a fuse.
