air cleaner.
Degree 2
Normally, only nonconductive pollution occurs. The pollution may become
conductive temporarily because of dew condensation.
An example of an environment of this degree is a place where electric equipment
can operate normally, such as a working office or a control panel.
Degree 3
Conductive pollution or dry and nonconductive pollution which can become
conductive when dew condensation occurs. An example of an environment of this
degree is a factory.
Degree 4 Conductive pollution that holds its conductivity due to conductive dust, rain or
snow. An example of an environment of this degree is the outdoors.
