IP43 vs IP61
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP43 and IP61 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 6) and liquid protection (level 3 vs 1). IP43 is rated for > 1 mm — small wires and spraying water (up to 60°), while IP61 provides dust-tight and vertically dripping water.
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.
IP61 is an ingress protection code that ensures dust-tight (no ingress of dust) and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 6 with second-digit (liquid) level 1.

The exact difference (IP43 vs IP61)
Solid protection
IP43
Level 4 — > 1 mm — Small Wires
IP61
Level 6 — Dust-Tight
IP43 provides "> 1 mm — Small Wires" (level 4), while IP61 provides "Dust-Tight" (level 6). IP61 is 2 levels higher.
Liquid protection
IP43
Level 3 — Spraying Water (up to 60°)
IP61
Level 1 — Vertically Dripping Water
IP43 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP61 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP43 provides 2 levels more liquid protection.

Recommendation
IP43 and IP61 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
