IP05 vs IP30
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP30 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 5 vs 0). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP30 provides > 2.5 mm — tool / wire and no protection.
Under IEC 60529, IP05 specifies no protection against solid objects and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 5.
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 (IP05 vs IP30)
Solid protection
IP05
Level 0 — No Protection
IP30
Level 3 — > 2.5 mm — Tool / Wire
IP05 provides "No Protection" (level 0), while IP30 provides "> 2.5 mm — Tool / Wire" (level 3). IP30 is 3 levels higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP30
Level 0 — No Protection
IP05 provides "Water Jets (6.3 mm nozzle)" (level 5), while IP30 provides "No Protection" (level 0). IP05 is 5 levels higher.

Recommendation
IP05 offers higher overall protection than IP30. Choose IP05 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
