Pollution Degree A measure of the contaminates that could occur in the
environment around and within a product. Typically the internal
environment inside a product is considered to be the same as the
external. Products should be used only in the environment for
which they are rated.
Pollution Degree 1
No pollution or only dry, nonconductive pollution occurs.
Products in this category are generally encapsulated,
hermetically sealed, or located in clean rooms.
Pollution Degree 2
Normally only dry, nonconductive pollution occurs.
Occasionally a temporary conductivity that is caused by
condensation must be expected. This location is a typical
office/home environment. Temporary condensation occurs
only when the product is out of service.
