efinition
Pollution degree 1
:
No pollution or only dry, non-conductive pollution occurs. The pollution has no influence.
Pollution degree 2
:
Normally only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by
condensation must be expected.
Pollution degree 3
:
Conductive pollution occurs, or, dry, non-conductive pollution occurs which becomes conductive due to
condensation which is expected.
Pollution degree 4
:
Persistent conductive pollution occurs, for example, the pollution cause by conductive dust, rain and snow.

Note
Overvoltage category definition
Category I
:
applies to equipment connected to a circuit where measures have been taken to reduce transient overvoltage to a
low level.
Category II
:
applies to equipment not permanently connected to the installation. Examples
are appliances, portable tools and
other plug-connected equipment;
Category III
:
applies to fixed equipment downstream of and including, the main distribution board. Examples are switchgear
and other equipment in an industrial installation;
Category IV
:
applies to equipment permanently connected at the origin of an installation (upstream of the main distribution
board). Example are electricity meters, primary overcurrent protection equipment and other equipment connected
directly to outdoor open lines.
