Enclosures

Enclosure
Enclosure series CDC and SDC are made of galvanized
steel sheet and with the performance standards
ISO 1461, IEC 61439-1, IEC 61439-5.
− IEC ISO 1461: Inorganic coatings - Hot dip
galvanized coatings on fabricated iron and steel
articles - Specifications and test methods (ISO 3
1461:1999).
− IEC 61439: Part 1: Low-voltage switchgear and
controlgear assemblies – Part 5: Assemblies for
power distribution in public networks.

The enclosures KSIK are powder coated steel
enclosures indoors. Environmental Class C1 and C2
according to:
− IEC ISO 12944-2: Paints and varnishes – Corrosion
protection of steel structures by painting.
− Part 2: Classification of environmental conditions
(ISO 12944-2:1998).

Degree of protection
The degree of protection is IP34D, in accordance with
the requirements of IEC 60529, unless otherwise stated
under “Technical data”.
Filling mass Sand or
Excavation depth Leca
To ensure an attractive and functional installation in the 0,1 m
ground, we recommend excavating to a depth at which
about 10 cm of the foundation is visible above the
restored surface. A marking label indicates the ground
level.

Special operating conditions
With this type of installation, consideration must be
given to the risk of condensation, dust, vibration and Base plate
impacts. To reduce the risk of condensation we recommend filling the
foundation with sand, leca and/or using a damp barrier type
Cxx-DB above the foundation.
All enclosures CDC and SDC have ventilation apertures
between the cover plate and the door and between the
door and the roof, both on the front and back of the
enclosure.

The ability of the enclosure to withstand external blows
and impacts has been checked by testing at –50° C in
accordance with the requirements for use in an Arctic
climate in IEC 61439-5.
