3-montage-cuivre-packshotFor more than 30 years, electrical equipment manufacturers have developed some very attractive busbar and distribution systems (standard busbar profiles & sizes, busbar supports, comb busbar, distribution systems & accessories) to distribute power inside these electrical equipments in an easy and safe way, especially when they are type-tested.
As far as I see it a lot of panel builder use partially or totally these busbar systems

The IEC 60439-X standards cover all Low Voltage switchgear and controlgear assemblies, i.e. all kind of switchboards and busbar trunking systems. Intended to ensure safety and power availability, they have a long track record of well proven and widely recognized tools, both for design and verification rules and as a reference for certification.

They are now evolving towards a new IEC 61439-X series, aiming to better cover all Assemblies and ensure that the specified performances are achieved.

The main changes may be summarized as follows :

1 – Recognition is made of the evolution of the organization of the industry, between Original Manufacturer and Assembly Manufacturer :

  • The conditions for Assembly Manufacturers to benefit from the design verifications made by the Original Manufacturer are stated.
