Installation (overvoltage) class definition
Installation (overvoltage) Class I refers to the signal level applicable to the device
measurement terminals connected to the source circuit where measures have been
taken to limit the instantaneous voltage to the corresponding low level.
Installed (overvoltage) Class II refers to the local distribution level for equipment
connected to a mains (AC supply).
The degree of pollution
2 class
Definition of pollution level
⚫ Pollution degree 1: no pollution, or only dry non-conductive pollution. This
pollution level has no impact. For example: clean room or air-conditioned office
environment.
⚫ Pollution level 2: generally only dry non-conductive pollution occurs.
Transient conduction due to condensation may sometimes occur. For example:
general indoor environment.
⚫ Pollution level 3: conductive pollution occurs, or dry non-conductive
pollution becomes conductive by condensation. For example, an outdoor
environment with a canopy.
⚫ Pollution level 4: Permanent conductive pollution through conductive dust,
rain, or snow. For example: outdoor places.
