IP30 vs IP03
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IP03 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 0) and liquid protection (level 0 vs 3). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IP03 provides no protection 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.
Designed for environments requiring no protection against solid objects and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects., IP03 is an IEC 60529 code combining solid level 0 with liquid level 3.

The exact difference (IP30 vs IP03)
Solid protection
IP30
Level 3 — > 2.5 mm — Tool / Wire
IP03
Level 0 — No Protection
IP30 provides "> 2.5 mm — Tool / Wire" (level 3), while IP03 provides "No Protection" (level 0). IP30 is 3 levels higher.
Liquid protection
IP30
Level 0 — No Protection
IP03
Level 3 — Spraying Water (up to 60°)
IP30 provides "No Protection" (level 0), while IP03 provides "Spraying Water (up to 60°)" (level 3). IP03 is 3 levels higher.

Recommendation
IP30 and IP03 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
