IP30 vs IPX4
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IPX4 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 0) and liquid protection (level 0 vs 4). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IPX4 provides no protection and splashing water (all directions).
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.
IPX4 (solid protection not specified) resists splashing water from any direction. A common minimum for bathroom and outdoor-covered appliances where dust sealing is not required.

Recommendation
IPX4 offers higher overall protection than IP30. Choose IPX4 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
