BS EN 61439-6:2012

Low-voltage switchgear and controlgear assemblies. Busbar trunking systems (busways)

Status : Current, Under review   Published : September 2012
Conformity to regulation : Designated



IEC 61439-6:2012 lays down the definitions and states the service conditions, construction requirements, technical characteristics and verification requirements for low voltage BTS (see 3.101) as follows:

- BTS for which the rated voltage does not exceed 1 000 V in case of a.c. or 1 500 V in case of d.c.;

- BTS intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electric energy consuming equipment;

- BTS designed for use under special service conditions, for example in ships, in rail vehicles, and for domestic applications (operated by unskilled persons), provided that the relevant specific requirements are complied with;

- BTS designed for electrical equipment of machines. Supplementary requirements for BTS forming part of a machine are covered by the IEC 60204 series. This first edition of IEC 61439-6 cancels and replaces the third edition of IEC 60439-2 (2000) and its Amendment 1 (2005), and constitutes a technical revision. This edition of IEC 61439-6 includes the following significant technical changes with respect to the latest edition of IEC 60439-2:

- alignment on the second edition of IEC 61439-1 (2011) regarding the structure and technical content, as applicable;

- introduction of new verifications, accordingly;

- correction of inconsistencies in resistance, reactance and impedance measurements and calculations;

- numerous editorial improvements.
