IP44 vs IP30
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP44 and IP30 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 3) and liquid protection (level 4 vs 0). IP44 is rated for > 1 mm — small wires and splashing water (all directions), while IP30 provides > 2.5 mm — tool / wire and no protection.
IP44 protects against small solid objects (1 mm) and splashing water from any direction. It is the common minimum rating for outdoor-covered fixtures and bathroom zone equipment.
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
IP44 offers higher overall protection than IP30. Choose IP44 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
