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.
