Degrees of protection
General technical data

In an installation, the degree of protection required for electrical

equipment depends on the environmental characteristics.

The degree of protection, ensured by the enclosure of equipment or by the cubicle containing the
equipment is expressed by the IP code which gives the level of protection against access to hazardous
parts, the ingress of foreign bodies and/or the ingress of water, in compliance with IEC 60529,
IEC 60947-1. Besides the IP symbol, the complete code has two figures followed (optionally) by two
additional letters. A short description of the elements used in IP coding is given below.
