The IP and IK degrees of protection provided by an enclosure must be specified as
a function of the various external influences defined by standard IEC 30364-5-51,
in particular:
b
b
presence of foreign solid bodies (code AE)
b
b
presence of water (code AD)
b
b
mechanical stress (code not specified)
b
b
capability of persons (code BA)

Prisma switchboards are designed for indoor installation.
Unless the rules, standards and regulations of a specific country stipulate otherwise,
Schneider Electric recommends the following IP and IK values based on French
guide UTE C 15-103 (March 2004).
Using the table
1
Opposite the relevant premises, read the recommended IP and IK values.
2
The
b
symbol indicates the enclosure or cubicle satisfying the criteria of the UTE
guide.
Any enclosure or cubicle with a higher degree of protection can also be used.
3
If several degrees of protection are possible (refer to the standard for more
details) and the
v
and
b
symbols are indicated (e.g. 24
v
/25
b
), enclosures that
correspond to the higher degree of protection (
b
) are suitable for the lower
degree of protection (
v
).
Example:
Selection of an enclosure for a laundry room.
Minimum degree of protection: IP21/IK02
Awall-mounted enclosure with a door (plain or transparent), a canopy and a gasket
offer IP43/IK08 degrees of protection and are therefore suitable for this application.
