IP04 vs IP30
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP04 and IP30 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 4 vs 0). IP04 is rated for no protection and splashing water (all directions), while IP30 provides > 2.5 mm — tool / wire and no protection.
The IP04 rating offers no protection against solid objects and protection against splashing water. Water splashed 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 4.
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.

Recommendation
IP04 offers higher overall protection than IP30. Choose IP04 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
