The standard for low-voltage switchgear and controlgear assemblies has been officially withdrawn and replaced by the IEC 61439 series . While older installations may still refer to it, new projects should follow IEC 61439-1 (General Rules) and IEC 61439-2 (Power Switchgear) . Key Installation Guidelines from IEC 60439-1
The phrase represents a genuine need: engineers want fast, offline access to critical electrical safety standards. While IEC 60439-1 is now obsolete, it remains a crucial reference for legacy systems. For new work, transition to IEC 61439-1. iec 604391 pdf install
