IP33 vs IP30
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP33 and IP30 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 3 vs 0). IP33 is rated for > 2.5 mm — tool / wire and spraying water (up to 60°), while IP30 provides > 2.5 mm — tool / wire and no protection.
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.
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.

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