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:
presence of foreign solid bodies (code AE)
presence of water (code AD)
mechanical stress (code not specified)
capability of persons (code BA)
....
Prisma Plus 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

Opposite the relevant premises, read the recommended IP and IK values.

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.

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-mount enclosure with a door (plain or transparent), a canopy and a gasket
offer IP31/IK08 degrees of protection and are therefore suitable for this application.
