IP54 vs IP43
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP54 and IP43 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 4) and liquid protection (level 4 vs 3). IP54 is rated for dust-protected and splashing water (all directions), while IP43 provides > 1 mm — small wires and spraying water (up to 60°).
IP54 is dust-protected (limited ingress, no harmful deposit) and resists splashing water from any direction. A versatile rating for industrial and outdoor-covered equipment in dusty, damp environments.
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 (IP54 vs IP43)
Solid protection
IP54
Level 5 — Dust-Protected
IP43
Level 4 — > 1 mm — Small Wires
IP54 provides "Dust-Protected" (level 5), while IP43 provides "> 1 mm — Small Wires" (level 4). IP54 is 1 level higher.
Liquid protection
IP54
Level 4 — Splashing Water (all directions)
IP43
Level 3 — Spraying Water (up to 60°)
IP54 handles 50–100 kPa (Splashing Water (all directions)), while IP43 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP54 provides 1 level more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP54 offers higher overall protection than IP43. Choose IP54 for harsher environments; IP43 may suffice for milder conditions and can be more cost-effective.
