Since November 2014, IEC/EN 61439 has replaced
the previously applicable standard IEC/EN 60439
for low-voltage switchgear and controlgear
assemblies. Distribution boards

C. comprises seven parts:
1.
The low-voltage switchgear standard
IEC/EN 60947-1
This standard applies for industrial low-voltage switchgear
assemblies used circuits 1,000 1,500 DC. Assemblies for construction sites
5. Power switchgear and controlgear assemblies (PSC)
3. This includes, for example,
the definition, characteristic features, information be
supplied, normal conditions for operation, installation and
transport well requirements for the construction and
verification characteristic features and behaviour. The standard addressed every
manufacturer and operator switchgear and controlgear
assemblies (SCA) 1,000 and 1,500 DC.
Assemblies for marinas, camping sites, electric
vehicles charging stations (preliminary standard)
In order confirm compliance with IEC/EN 61439, it
is important that you always refer Part and one of
the following parts.
Irrespective whether you assemble the SCA stationary
or mobile, with without enclosure system.
