Characteristic Description
Overvoltage Category Description Terminals on this product may have different installation (overvoltage) category
designations. The installation categories are:
CAT III Distribution-level mains (usually permanently connected). Equipment at this
level is typically in a fixed industrial location.
CAT II Local-level mains (wall sockets). Equipment at this level includes
appliances, portable tools, and similar products. Equipment is usually
cord-connected.
CAT I Secondary (signal level) or battery operated circuits of electronic equipment.
Overvoltage Category Overvoltage Category II (as defined in IEC61010-1)
Pollution Degree Description 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.
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 Pollution Degree 2 (as defined in IEC61010-1). Note: Rated for indoor use only.
