Safety class
Class 2
Pollution degree description
A measure of the contaminants 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.
■
Pollution Degree 3. Conductive pollution, or dry, nonconductive
pollution that becomes conductive due to condensation. These are
sheltered locations where neither temperature nor humidity is
controlled. The area is protected from direct sunshine, rain, or
direct wind.
■
Pollution Degree 4. Pollution that generates persistent conductivity
through conductive dust, rain, or snow. Typical outdoor locations.
