1
Pollution degree 1 No pollution or only dry and non-conductive pollution occurs.
Pollution degree 2 Only non-conductive pollution occurs. Occasionally, condensation can cause temporary conductivity.
Pollution degree 3 Conductive pollution or dry non-conductive pollution that becomes conductive due to condensation.
Pollution degree 4 The pollution generates persistent conductivity caused by conductive dust, rain or snow.
2
The types of electrical connections of the functional units inside the equipment are indicated by a 3-letter code: the first letter indicates
the type of electrical connection of the main incoming circuit; the second letter indicates the type of electrical connection of the main
outgoing circuit and the third letter indicates the type of electrical connection of the auxiliary circuits. The three letters have the
following meanings:
F refer to fixed connections (the connection is connected or disconnected by means of a tool);
D refers to disconnected connections (the connection is connected or disconnected by intervening manually without using a
tool);
W refers to removable connections (the connection is connected or disconnected by setting the functional unit to service or
disconnected mode).
3
B Environment Low voltage public network for residential, commercial and light industrial systems.
A Environment Low voltage non-public network or industrial systems, including sources of high interference.
