|
|
| Category | Descriptions |
|
|
|
| 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 |
|

Pollution degree | A measure of the contaminants that can 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 cleanrooms. |
| 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. |
