IP30 vs IP43
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IP43 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 4) and liquid protection (level 0 vs 3). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IP43 provides > 1 mm — small wires and spraying water (up to 60°).
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.
IP43 protects against 1 mm solid objects and spraying water up to 60° from vertical. A practical rating for sheltered equipment subject to light angled spray, such as covered outdoor fixtures.

The exact difference (IP30 vs IP43)
Solid protection
IP30
Level 3 — > 2.5 mm — Tool / Wire
IP43
Level 4 — > 1 mm — Small Wires
IP30 provides "> 2.5 mm — Tool / Wire" (level 3), while IP43 provides "> 1 mm — Small Wires" (level 4). IP43 is 1 level higher.
Liquid protection
IP30
Level 0 — No Protection
IP43
Level 3 — Spraying Water (up to 60°)
IP30 provides "No Protection" (level 0), while IP43 provides "Spraying Water (up to 60°)" (level 3). IP43 is 3 levels higher.

Recommendation
IP43 offers higher overall protection than IP30. Choose IP43 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
