Сertificate IEC 60529. Protection levels ensured by housings.

Electrical safety class           Environmental testing to ensure protection

The enclosure of electrical and electronic equipment designed to operate in specific environments where dust, corrosive substances, moisture, or water ingress may occur is of paramount importance for reducing the electric shock, fire, or explosion hazards.
