IP20 vs IP63
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP20 and IP63 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 6) and liquid protection (level 0 vs 3). IP20 is rated for > 12.5 mm — finger and no protection, while IP63 provides dust-tight and spraying water (up to 60°).
IP20 protects against contact with a finger and solid objects larger than 12.5 mm. It has no water protection and is intended for dry, indoor use such as consumer electronics and IT equipment.
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.

The exact difference (IP20 vs IP63)
Solid protection
IP20
Level 2 — > 12.5 mm — Finger
IP63
Level 6 — Dust-Tight
IP20 provides "> 12.5 mm — Finger" (level 2), while IP63 provides "Dust-Tight" (level 6). IP63 is 4 levels higher.
Liquid protection
IP20
Level 0 — No Protection
IP63
Level 3 — Spraying Water (up to 60°)
IP20 provides "No Protection" (level 0), while IP63 provides "Spraying Water (up to 60°)" (level 3). IP63 is 3 levels higher.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP63 offers higher overall protection than IP20. Choose IP63 for harsher environments; IP20 may suffice for milder conditions and can be more cost-effective.
