The EN 60529 standard covers the protection of electrical equip-
ment by means of housings, covers or equivalent, and includes:
•
Protection of persons against accidental contact with live or
moving parts within the housing and protection of the equip-
ment against the ingress of solid foreign matter (touch protec-
tion and protection against ingress of solid foreign matter)
•

(water protection)
•
Abbreviations for the internationally agreed degrees of
protection
The degrees of protection are specified by abbreviations
comprising the code letters IP and two digits.
The devices are intended for indoor installation and are suitable
for climatic environmental conditions of Class 3K3 according to
EN 60721, higher requirements fulfilled on request.
Note:
For transport reasons, the top covers are delivered separately
and must be fitted on site.
The protective top cover for IP21 and the protective top cover in
