The document defines IK and IP codes for protection levels provided by assembly enclosures. IK codes indicate protection against mechanical impacts, with higher codes indicating the ability to withstand higher impact energies. IP codes indicate protection against contact with live parts, ingress of solid objects and liquids. The IP code is made up of two digits that each range from 0 to 9, with higher numbers indicating greater protection. Requirements for minimum IP protection levels for assemblies are provided based on indoor versus outdoor use and presence of hazardous parts.

1. Degree of protection provided by an ASSEMBLY
enclosure (IP & IK)
Definitions as per IEC 61439:
IK (Protection against mechanical impact):
The degree of protection provided by an ASSEMBLY enclosure against
mechanical impact, if necessary, shall be defined by the relevant ASSEMBLY
standards and verified in accordance with IEC 62262.
IP (Protection against contact with live parts, ingress of solid
foreign bodies and liquids):
The degree of protection provided by any ASSEMBLY against contact with
live parts, ingress of solid foreign bodies and liquid is indicated by the IP
code according to IEC 60529.

2. Schneider Electric 2- Division - Name – Date
 IK.
Relation between IK code and impact energy:
IK codes can be selected according to the risks of impacts on a given site:

3. Schneider Electric 3- Division - Name – Date
 IP.
Arrangement of the IP Code:
Where a characteristic numeral is not required to be specified, it shall be replaced by the
letter “X” (“XX” if both numerals are omitted).

4. Schneider Electric 4- Division - Name – Date
 IP.
 ASSEMBLIES can be divided to attain one or more of the following conditions between
functional units, separate compartments or enclosed protected spaces:
 Protection against contact with hazardous parts. The degree of protection shall be at
least IP XXB
 Protection against the passage of solid foreign bodies. The degree of protection shall
be at least IP 2X.
The degree of protection of an enclosed ASSEMBLY shall be at least IP 2X, after
installation in accordance with the ASSEMBLY manufacturer's instructions. The degree of
protection provided from the front of a dead front ASSEMBLY shall be at least IP XXB.
NOTE The degree of protection IP 2X covers the degree of protection IP XXB.
For ASSEMBLIES for indoor use where there is no requirement for protection against
ingress of water, the following IP codes are preferred:
IP 00, IP 2X, IP 3X, IP 4X, IP 5X, IP 6X.
For ASSEMBLIES for outdoor use having no supplementary protection, the second
characteristic numeral shall be at least 3.

 IP.

6. The IP of Schneider-Electric switchboards is up to IP55 and of
Universal Enclosure is up to IP66.
The IK of Schneider-Electric switchboards and Universal
Enclosure is IK10 for which equipped with plain door and IK08
for which equipped with transparent door.
