IP30 vs IP67
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IP67 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 6) and liquid protection (level 0 vs 7). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IP67 provides dust-tight and temporary immersion (up to 1 m).
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.
IP67 is dust-tight and withstands temporary immersion in water up to 1 meter for 30 minutes. The go-to rating for outdoor and rugged devices that may be briefly submerged.

The exact difference (IP30 vs IP67)
Solid protection
IP30
Level 3 — > 2.5 mm — Tool / Wire
IP67
Level 6 — Dust-Tight
IP30 provides "> 2.5 mm — Tool / Wire" (level 3), while IP67 provides "Dust-Tight" (level 6). IP67 is 3 levels higher.
Liquid protection
IP30
Level 0 — No Protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP30 provides "No Protection" (level 0), while IP67 provides "Temporary Immersion (up to 1 m)" (level 7). IP67 is 7 levels higher.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP30. Choose IP67 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
