IP20 vs IP13
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP20 and IP13 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 1) and liquid protection (level 0 vs 3). IP20 is rated for > 12.5 mm — finger and no protection, while IP13 provides > 50 mm — back of hand 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 IP13 rating offers protection against solid objects larger than 50 mm 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 1 with second-digit (liquid) level 3.

The exact difference (IP20 vs IP13)
Solid protection
IP20
Level 2 — > 12.5 mm — Finger
IP13
Level 1 — > 50 mm — Back of Hand
IP20 provides "> 12.5 mm — Finger" (level 2), while IP13 provides "> 50 mm — Back of Hand" (level 1). IP20 is 1 level higher.
Liquid protection
IP20
Level 0 — No Protection
IP13
Level 3 — Spraying Water (up to 60°)
IP20 provides "No Protection" (level 0), while IP13 provides "Spraying Water (up to 60°)" (level 3). IP13 is 3 levels higher.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP13 offers higher overall protection than IP20. Choose IP13 for harsher environments; IP20 may suffice for milder conditions and can be more cost-effective.
