Additional letter

The additional letter is used only if the actual protection of persons is higher than that

indicated by the first characteristic numeral of the IP code.

Additional letter

Protection

A

A Protected against access with back of hand

B

B Protected against access with a 12 mm diameter finger

C

C Protected against access with a 2.5 mm diameter tool

D

D Protected against access with a 1 mm diameter wire

If only the protection of persons is of interest, the two characteristic numerals are

replaced by the letter "X", e.g. IPXXB.

Illustration of the above explanations:

Protection against solid foreign objects

larger than 2.5 mm

No protection

Remarks

The degree of protection IP must always be read and understood numeral by

numeral and not as a whole.

For example, an IP31 wall-mount enclosure is suitable for an environment that

requires a minimum degree of protection IP21. However an IP30 wall-mount

enclosure is not suitable.

the degrees of protection indicated in this catalogue are valid for the enclosures as

presented. However, the indicated degree of protection is guaranteed only when

installation and device mounting are carried out in accordance with professional

standards that conserve the initial degree of protection.

IK code
