Degrees of protection

The degrees of protection for protection against contact and foreign objects and against water are indicated by characteristic numerals. The IP Code is characterised by 2 numerals. For the USA and Canada, the IP codes can roughly be compared with NEMA ICS6-1983/EEMAC E14-2 (for USA) or CSA-C22.1/CSA-C22.2 No. 94 (for Canada). (For example IP20 equivalent to enclosure type 1 or IP54 equivalent to enclosure type 3.)

1. code number: protection against contact and foreign bodies
2. code number: splash water protection

Protection against contact and foreign bodies Naming Explanation Splash water protection Naming Explanation
0 No protection
1 Protection against foreign bodies ≥ 50 mm Protection against accidental large-area contact. Protected against solid foreign bodies with a diameter of 50 mm and larger 1 Protection against vertically falling dripping water Drops of water falling vertically must not have any harmful effect
2 Protection against foreign bodies ≥ 12.5 mm Protection against touching with fingers. Protected against solid foreign bodies with a diameter of 12.5 mm and larger 2 Protection against dripping water at up to 15° enclosure inclination Drops falling vertically shall have no harmful effects if the enclosure is inclined by an angle of 15° on either side of vertical
