Protection class II
Electrical devices that fall under protection
class II have reinforced or double insulation
to the amount of the rated insulation voltage
between active and accessible parts (VDE
0100 part 410, 412.1). They usually have
no connection to the protective conductor.
Even if they have conductive surfaces, they
are protected from contact with other live
parts by reinforced or double insulation.
Products labelled with this symbol meet
the requirements of the guidelines of the
European Community.
These symbols indicate the polarity of the
