IP04 vs IP43
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP04 and IP43 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 4) and liquid protection (level 4 vs 3). IP04 is rated for no protection and splashing water (all directions), while IP43 provides > 1 mm — small wires and spraying water (up to 60°).
The IP04 rating offers no protection against solid objects and protection against splashing water. Water splashed against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 4.
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 (IP04 vs IP43)
Solid protection
IP04
Level 0 — No Protection
IP43
Level 4 — > 1 mm — Small Wires
IP04 provides "No Protection" (level 0), while IP43 provides "> 1 mm — Small Wires" (level 4). IP43 is 4 levels higher.
Liquid protection
IP04
Level 4 — Splashing Water (all directions)
IP43
Level 3 — Spraying Water (up to 60°)
IP04 handles 50–100 kPa (Splashing Water (all directions)), while IP43 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP04 provides 1 level more liquid protection.

Recommendation
IP43 offers higher overall protection than IP04. Choose IP43 for harsher environments; IP04 may suffice for milder conditions and can be more cost-effective.
