IEC 61439
The new standart for low-voltage swichgear and controlgear
ASSEMBLIES
A low-voltage switchgear and controlgear assembly
(ASSEMBLY) is a combination of low-voltage switching
devices together with associated equipment (for control
ling, measuring, signalling, etc.) complete with all the
internal mechanical and electrical interconnections and
structural parts. As with every component of an electrical
installation, the ASSEMBLY also has to comply with its
appropriate standard.
In January 2009 the IEC 61439, the new standard for low
voltage switchgear and controlgear ASSEMBLIES, was
published. This was the aim of an international project group
which had been working on a task named ”radical restructuring
and revision of IEC 60439 series” since 1998. This initiative
was introduced by several countries following dissatisfaction
with the IEC 60439 series. The purpose was to harmonise
and define all general requirements for low-voltage electrical
ASSEMBLIES.
