Appendix: Protection Category Definition

No pollution or only dry, non-conductive pollution occurs. The pollution has no influence

Pollution Degree Ⅰ

Normally only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.

Pollution Degree Ⅱ

Conductive pollution occurs, or dry, non-conductive pollution occurs, which becomes conductive due to condensation, which is expected.

Pollution Degree Ⅲ

Persistent conductive pollution occurs, for example, the pollution caused by conductive dust, rain and snow.
