IEC 60439 problems
Reasons for the new standard series IEC 61439
With the new IEC 61439 the series of standards for low-voltage switchgear and controlgear assemblies was radically
revised and restructured. The main reasons for this were the following key points of criticism about the previous
IEC 60 439 standard.
Difficult to understand
and execute
TTA / PTTA dilemma
IEC60439 part 1 with
double function
• Grey areas leading
to subjective
interpretations
• Wrongly interpreted
categories
• Product standard
and
• Limited applicability
• Poorly structured
content
• classification useless
for end customers
• General
requirements for all
other standards of
this series
Some manufacturers
and specific market
segments are ignoring
the IEC 60439.
