IP30 vs IP58
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IP58 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 5) and liquid protection (level 0 vs 8). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IP58 provides dust-protected and continuous immersion (manufacturer-specified).
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.
IP58 is dust-protected and rated for continuous immersion in water under manufacturer-specified conditions. A niche rating for equipment that must operate submerged while allowing limited dust ingress.

The exact difference (IP30 vs IP58)
Solid protection
IP30
Level 3 — > 2.5 mm — Tool / Wire
IP58
Level 5 — Dust-Protected
IP30 provides "> 2.5 mm — Tool / Wire" (level 3), while IP58 provides "Dust-Protected" (level 5). IP58 is 2 levels higher.
Liquid protection
IP30
Level 0 — No Protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP30 provides "No Protection" (level 0), while IP58 provides "Continuous Immersion (manufacturer-specified)" (level 8). IP58 is 8 levels higher.

Recommendation
IP58 offers higher overall protection than IP30. Choose IP58 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
