The IEC 61439 series is the current IEC series for low voltage switchgear and control gear assemblies and has been fully adopted in Europe since 2014.

  • Only AS/NZS 61439 is acceptable for specification
  • For upgrades to existing switchboards built to previous standards
  • Replacing like for like electrical components is allowable
  • Any modifications to the switchboard itself will require that section to be upgraded to the new standard, which may require upgrading to a whole new switchboard.

Why the standard is changing?

ProcessThe current standard AS/NZS 3439 was first introduced in 1998. There have since been many changes and improvements to electrical switchgear, design, manufacture and safety processes. Due to some areas of common misunderstanding in the old standard the new standard aims to clarify legal and financial responsibilities in specification, testing, design and build between user and the assembly manufacturer.
