IP Ratings – Ingress Protection (IP) ratings is the standard rating for sealing electrical devices against dust and moisture.
|IP Rated Enclosures|
|First Digit (intrusion protection)|
|0||No special protection|
|1||Protection from a large part of the body such as a hand (but no protection from deliberate access); from solid objects greater than 50mm in diameter.|
|2||Protection against fingers or other object not greater than 80mm in length and 12mm in diameter.|
|3||Protection from entry by tools, wires etc, with a diameter of 2.5 mm or more.|
|4||Protection against solid bodies larger than 1mm (eg fine tools/small etc).|
|5||Protected against dust that may harm equipment.|
|6||Totally dust tight.|
|Second Digit (moisture protection)|
|1||Protection against condensation.|
|2||Protection against water droplets deflected up to 15° from vertical|
|3||Protected against spray up to 60° from vertical.|
|4||Protected against water spray from all directions.|
|5||Protection against low pressure water jets (all directions)|
|6||Protection against string water jets and waves.|
|7||Protected against temporary immersion.|
|8||Protected against prolonged effects of immersion under pressure.|
IP Ratings look like this: IP65, IP45, IP54, etc.
Example: An IP65 rating means it is totally dust tight and is protected from low pressure water jets.
