Protection Class

The IP (Ingress Protection) rating system is published by the IEC (International Electrotechnical Commission) and classifies the degree of protection that the enclosure provides against solid objects and liquids in order to operate the enclosed electrical equipment.

3 Protected Against Direct Sprays of Water up to 60° from Vertical
4 Protected Against Water Splashing from any Direction
5 Protected Against Low Pressure Water Jets from any Direction
6 Protected Against High Pressure Water Jets from any Direction

8 Protected Against Long Periods of Immersion under Pressure

IP69K

ip69k_page

IP69K is a rating of the German standard DIN 40050-9 extending the IEC 60529 rating system described above. IP69K is developed for areas where extra protection is needed against high-pressure and high-temperature. Typical applications that require this rating are mobile machinery and food industry where equipment is cleaned intensively with high pressure or steaming water.

Comparing NEMA and IP Enclosure Ratings

This is a cross reference for comparing NEMA and IP enclosure ratings. This comparison is only approximate, and it is the responsibility of the user to verify the enclosure rating necessary for the given application.
