IP30 vs IP25
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IP25 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 2) and liquid protection (level 0 vs 5). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IP25 provides > 12.5 mm — finger and water jets (6.3 mm nozzle).
IP30 protects against tools and 2.5 mm solid objects but offers no water protection. A basic indoor rating for equipment in dry, low-dust environments where only tool-access protection is required.
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 (IP30 vs IP25)
Solid protection
IP30
Level 3 — > 2.5 mm — Tool / Wire
IP25
Level 2 — > 12.5 mm — Finger
IP30 provides "> 2.5 mm — Tool / Wire" (level 3), while IP25 provides "> 12.5 mm — Finger" (level 2). IP30 is 1 level higher.
Liquid protection
IP30
Level 0 — No Protection
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP30 provides "No Protection" (level 0), while IP25 provides "Water Jets (6.3 mm nozzle)" (level 5). IP25 is 5 levels higher.

Recommendation
IP25 offers higher overall protection than IP30. Choose IP25 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
