Protection types - IP classification according to ČSN EN 60 529
Protection levels against contact with dangerous parts are indicated by the complementary code in the form of a letter.
The letter added after the second digit of the IP designation indicates the protection level of persons against contact with dangerous parts, e.g. IP 10B.
These letters are used only in the following cases:
* if the actual protection against contact with dangerous parts is higher than that indicated by the first characteristic digit
* if only protection against contact with dangerous parts is specified, the first characteristic digit is then replaced by an X
This higher protection level can be ensured by barriers, spacings inside the housing or suitable shape of the openings.
A - Protected against contact with the back of the hand
B - Protected against contact with fingers
C - Protected against contact with tools
D - Protected against contact with wires
