IP PROTECTION RATINGS
It is a two-digit coding system (e.g., IP 65) used to indicate the degrees of protection provided by the enclosure against access to hazardous parts.
· The first digit indicates the degree of protection against the ingress of solid objects.
· The second digit indicates the degree of protection against the ingress of liquids.
TABLE 1 – Protection Ratings for the First Digit (Solids)
| 0 | Not protected |
| 1 | Protected against solid objects with a diameter greater than 50 mm. |
| 2 | Protected against solid objects with a diameter greater than 12 mm. |
| 3 | Protected against solid objects with a diameter greater than 12 mm. |
| 4 | Protected against solid objects with a diameter greater than 2.5 mm. |
| 5 | Protected against dust ingress sufficient to prevent harm to the equipment. |
| 6 | Completely dust-tight |
Table 2 – Protection Ratings for the Second Digit (Liquids)
| 0 | Not protected |
| 1 | Protected against vertically falling water drops |
| 2 | Protected against falling water drops at a maximum inclination of 15 degrees |
| 3 | Protected against spraying water |
| 4 | Protected against water splashes from all directions |
| 5 | Protected against water jets from all directions |
