Heavy Duty Connector Pollution Degree

Pollution level 1: No pollution or only dry non-conductive pollution occurs, which has no effect. Such as computer rooms and measuring equipment. Pollution level 2: Only non-conductive pollution occurs, but it must be expected that condensation will occasionally cause short-term conductive pollution. Such as residential buildings, commercial buildings, laboratories, and precision machinery workshops. Pollution level 3: There is conductive pollution or dry non-conductive pollution becomes conductive pollution due to expected condensation. Such as unheated warehouses, workshops or boiler rooms, as well as electrical equipment or machine tools of the unit. Connector Insert is designed according to this pollution level. Pollution level 4: Persistent conductive pollution is caused, for example, by conductive dust or rain and snow. Such as equipment on the roof of open air or outdoor spaces, trains or trams.
