IP63 means the enclosure has solid-protection level 6 (Dust-Tight) and liquid-protection level 3 (Spraying Water (up to 60°)). No ingress of dust whatsoever. Protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.

Can IP63 be used outdoors?

No. IP63 only provides spraying water (up to 60°) — it is not suitable for outdoor rain or spray exposure. Use it indoors or in fully enclosed dry locations.

Yes. The first digit 6 means no ingress of dust whatsoever — verified in a dust chamber under reduced internal pressure for 8 hours per IEC 60529.

IP63

Last updated: Aug 9, 2026

The IP63 classification guarantees dust-tight (no ingress of dust) and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 6 with second-digit (liquid) level 3.

What IP63 means

The IP code IP63 is part of the IEC 60529 standard for ingress protection. The first characteristic numeral, 6, indicates the level of protection against solid objects and access to hazardous parts. The second numeral, 3, indicates the level of protection against the ingress of water. Together, these digits describe exactly what an enclosure rated IP63 can withstand.

For solid protection, the digit 6 means the enclosure is dust-tight. Protected against access to hazardous parts with a wire. No ingress of dust whatsoever. The test method is dust chamber (talcum powder) for 8 hours (2 hours if equipment is in operation) with enclosure under reduced internal pressure; no dust ingress permitted.

For liquid protection, the digit 3 means the enclosure resists spraying water (up to 60°). Protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects. The test procedure is oscillating tube or spray nozzle with 80° aperture; water pressure 50–150 kpa depending on device; 5 minutes minimum.

IP63 vs IP64: the higher rating adds splashing water. When specifying IP63 for a project, confirm the rating certificate from the manufacturer and consider that seals degrade over time with temperature cycling, UV exposure, and chemical contact.
