IP24 vs IP25
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP24 and IP25 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 4 vs 5). IP24 is rated for > 12.5 mm — finger and splashing water (all directions), while IP25 provides > 12.5 mm — finger and water jets (6.3 mm nozzle).
With IP24, an enclosure receives protection against solid objects larger than 12.5 mm and protection against splashing water. Water splashed against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 4.
IP25 is an ingress protection code that ensures protection against solid objects larger than 12.5 mm and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 5.

The exact difference (IP24 vs IP25)
Solid protection
IP24
Level 2 — > 12.5 mm — Finger
IP25
Level 2 — > 12.5 mm — Finger
Both IP24 and IP25 share the same solid protection: > 12.5 mm — Finger.
Liquid protection
IP24
Level 4 — Splashing Water (all directions)
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP24 handles 50–100 kPa (Splashing Water (all directions)), while IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP25 provides 1 level more liquid protection.

No direct NEMA equivalent.
Recommendation
IP25 offers higher overall protection than IP24. Choose IP25 for harsher environments; IP24 may suffice for milder conditions and can be more cost-effective.
