IP43 vs IP44
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP43 and IP44 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 3 vs 4). IP43 is rated for > 1 mm — small wires and spraying water (up to 60°), while IP44 provides > 1 mm — small wires and splashing water (all directions).
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.
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.

The exact difference (IP43 vs IP44)
Solid protection
IP43
Level 4 — > 1 mm — Small Wires
IP44
Level 4 — > 1 mm — Small Wires
Both IP43 and IP44 share the same solid protection: > 1 mm — Small Wires.
Liquid protection
IP43
Level 3 — Spraying Water (up to 60°)
IP44
Level 4 — Splashing Water (all directions)
IP43 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP44 handles 50–100 kPa (Splashing Water (all directions)). IP44 provides 1 level more liquid protection.

Recommendation
IP44 offers higher overall protection than IP43. Choose IP44 for harsher environments; IP43 may suffice for milder conditions and can be more cost-effective.
