Pollution Degree Description
A measure of the contaminants that could occur in the envir onment 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 m ust 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 l ocations 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.
Pollution Degree
Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated for indoor use only.

Measurement Category III. For measurements performed in the building installation.
Measurement Category II. For measurements performed on circuits directly connected to the low-voltage installation.
Measurement Category I. For measurements perform ed on circuits not directly connected to MAINS.
Overvoltage Ca tegory
Overvoltage Category II (as defined in IEC 61010-1).
