IP30 vs IP44
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IP44 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 4) and liquid protection (level 0 vs 4). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IP44 provides > 1 mm — small wires 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.
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.

IP44
Level 4 — > 1 mm — Small Wires
IP30 provides "> 2.5 mm — Tool / Wire" (level 3), while IP44 provides "> 1 mm — Small Wires" (level 4). IP44 is 1 level higher.
Liquid protection
IP30
Level 0 — No Protection
IP44
Level 4 — Splashing Water (all directions)
IP30 provides "No Protection" (level 0), while IP44 provides "Splashing Water (all directions)" (level 4). IP44 is 4 levels higher.

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.
