What is IP?
While selecting equipment type and its mounting place ensure compliance of operating conditions to the indicated ingress protection parameters. Any electrical appliance must meet two ingress protection demands:
- ensure safety to the user and service personnel and to protect the electrical components located inside the appliance against environmental impact, i.e. Ingress Protection (IP).
IP rating refers to dust-proof and moisture protection of the equipment and its electrical safety.
Information regarding protection rating marked IP and two digits indicating protectiont degree is specified in technical documentation and on casing of the equipment, i.e. IP20 or IP65. The first digit shows the degree of protection against access to hazardous objects. Protection characteristics defined by the first digit is stated in the table 1. The second digit shows the degree of protection against water ingress and its characteristics are stated in the table 2.
Table 1
| First digit | Protection characteristics | Description | ||
|---|---|---|---|---|
| х | No ingress protection | Oped construction, no dust protection and protection against contact with current-carrying parts. | ||
| 1 | Large-scale objects protection | Protection from objects equal to or greater than 50 mm and hand accidental touch to currentcarrying parts. | ||
| 2 | Medium-size objects protection | Protection from objects equal to or greater than 12 mm. and fingers touch to current-carrying parts. | ||
| 3 | Small-size objects protection | Protection from objects equal to or greater than 2,5 mm and entry by tools, wires or fingers. | ||
| 4 | Sand protection | Protection from objects equal to or greater than 1 mm and entry by tools, wires or fingers. | ||
| 5 | Dust protection | Significant dust quantity can be accumulated inside the casing which does not disturb the rated operation. Full protection against touch to current-carrying parts. | ||
| 6 | Dust-tight protection | No dust penetration inside the equipment. |
Table 2
| Second digit | Protection characteristics | Description | ||
|---|---|---|---|---|
| х | No ingress protection | Open construction with no protection against water. | ||
| 1 | Protection against vertically dripping water | Water drops dripping vertically do not damage equipment. | ||
| 2 | Protection from vertically dripping water (15° tilted) | Water drops falling vertically at 15° do not damage equipment. | ||
| 3 | Protection from sprayed water | Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect. | ||
| 4 | Protection from splashed water | Water splashing against the enclosure from any direction shall have no harmful effects for the equipment in the casing. | ||
| 5 | Protection from jetting water | Water projected by a nozzle against enclosure from any direction shall have no harmful effects for the equipment in the casing. | ||
| 6 | Protection from powerfully jetting water | Water projected in powerful jets against the enclosure from any direction shall have no harmful effects for the equipment in the casing. | ||
| 7 | Protection against temporary immersion in water | Ingress of water in harmful quantity shall not be possible when the equipment is immersed in water. | ||
| 8 | Protection against complete, permamnent immersion in water | The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer |
