Degree of protection provided by enclosures
For safety reasons, electrical equipment needs to be protected against outside influences. The basis for the determination is the stan-
dard IEC 529 titled ‘Degree of protection provided by enclosures (IP – Code)'.
Using a standardized test procedure the extent of the protection class is verified. To classify different housings according to their protec-
tion class, a designation system is used which consists of the code – letters 'IP' and two code numbers.

Meaning of the 1st characteristic numeral
The first numeral describes the protection of the housing against intrusion of foreign bodies as well as the protection of people against
dangerous parts or influences. Because of this, there are two descriptions and definitions for each of the first code letter.
