IP03 vs IP61
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP03 and IP61 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 6) and liquid protection (level 3 vs 1). IP03 is rated for no protection and spraying water (up to 60°), while IP61 provides dust-tight and vertically dripping water.
Designed for environments requiring no protection against solid objects and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects., IP03 is an IEC 60529 code combining solid level 0 with liquid level 3.
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 (IP03 vs IP61)
Solid protection
IP03
Level 0 — No Protection
IP61
Level 6 — Dust-Tight
IP03 provides "No Protection" (level 0), while IP61 provides "Dust-Tight" (level 6). IP61 is 6 levels higher.
Liquid protection
IP03
Level 3 — Spraying Water (up to 60°)
IP61
Level 1 — Vertically Dripping Water
IP03 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP61 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP03 provides 2 levels more liquid protection.

Recommendation
IP61 offers higher overall protection than IP03. Choose IP61 for harsher environments; IP03 may suffice for milder conditions and can be more cost-effective.
