IEC Rating System

IEC Enclosure Ratings are based on a two digit numbering system as listed below.

The first digit indicates a degree of protection against solid particles, and the second digit indicates a degree of protection against liquids.

IP Number Designations

1st Digit – Solid Particles

0  – No protection
– Protection against large foreign bodies
2  – Protection against medium foreign bodies
3  – Protection against small foreign bodies
4  – Protection against granular foreign bodies
5  – Protection from deposit of dust
6  – Protection from access of dust

2nd Digit – Liquids

0  – No protection
1  – Protection against vertical dripping water
2  – Same as 1 above when tilted up to 15 degrees
3  – Protection against sprayed water at 60 degrees
4  – Protection against splashed water
5  – Protection against jetted water
6  – Protection against flooding
7  – Protection in dipped state
8  – Protection in submerged state
