After nine years of committee debate the 3rd Editions of IEC 61439-1 and IEC 61439-2, the standards for power switchgear and controlgear assemblies, have been published.


The new editions include changes, the significance of which will affect the way assemblies are specified and used. All the changes are either a recognition of the changing needs of assemblies in the market, technical advances, further options in design verification or clarifications.


These changes have been made with simple objectives in mind; ensuring assemblies are fit for purpose and there is a clear understanding of the capabilities of the assembly between specifier and manufacturer.
