IP30 vs IP33
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IP33 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 0 vs 3). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IP33 provides > 2.5 mm — tool / wire and spraying water (up to 60°).
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.
IP33 protects against tools and 2.5 mm objects plus spraying water up to 60° from vertical. A practical rating for indoor equipment subject to light spray or for sheltered outdoor fixtures.

The exact difference (IP30 vs IP33)
Solid protection
IP30
Level 3 — > 2.5 mm — Tool / Wire
IP33
Level 3 — > 2.5 mm — Tool / Wire
Both IP30 and IP33 share the same solid protection: > 2.5 mm — Tool / Wire.
Liquid protection
IP30
Level 0 — No Protection
IP33
Level 3 — Spraying Water (up to 60°)
IP30 provides "No Protection" (level 0), while IP33 provides "Spraying Water (up to 60°)" (level 3). IP33 is 3 levels higher.

Recommendation
IP33 offers higher overall protection than IP30. Choose IP33 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
