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. For example,
appliances, portable tools and other plug-connected equipment;
Category III: applies to fixed downstream equipment, including the main distribution board. For
example,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).For example, electricity meters, primary
overcurrent protection equipment and other equipment connected directly to
outdoor open lines.

Environment Category Definition
Outdoor : the ambient air temperature is -20~50℃. Relative humidity range is from 4% to 100%,
applied to PD3.
Indoor unconditioned: the ambient air temperature is -20~50 ℃. Relative humidity range is from
5% to 95%, applied to PD3.
Indoor conditioned: the ambient air temperature is 0~40 ℃. Relative humidity range is from 5% to
85%, applied to PD2.
Pollution Degree Definition
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. However, a temporary
conductivity occasionally caused by condensation must be expected.
Pollution degree 3: Conductive pollution occurs. Or dry, non-conductive pollution 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.
