EN 61439 / IEC 61439 / VDE 0660-600
The EN 61439 standard series replaces the EN 60439 standard series. The standard series EN 61439 aims to
harmonise the rules and requirements for low voltage switching device combinations.
In the EN 61439 standard series, the relevant part of the standard always applies, such as EN 61439-6 busbars,
together with Part 1 of the standard (EN 61439-1).
