also of switchgear and controlgear assemblies, for use in different environmental
conditions. For each switchgear and controlgear assembly, the protection type is
specified with the IP code according to IEC 60529 and verified according to
EN (IEC) 61439.
-
Verification of protection against ingress of foreign bodies and against
