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.
Pollution degree rating
Pollution Degree 2 (as defined in IEC 61010-1). Rated for indoor, dry location use only.
IP rating
IP20 (as defined in IEC 60529).
Measurement and overvoltage category descriptions
Measurement terminals on this product may be rated for measuring mains voltages from one or more of the following categories (see
specific ratings marked on the product and in the manual).
• Measurement Category II. For measurements performed on circuits directly connected to the low-voltage installation.
• Measurement Category III. For measurements performed in the building installation.
• Measurement Category IV. For measurements performed at the source of low-voltage installation.
