IP01 vs IP03
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP01 and IP03 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 1 vs 3). IP01 is rated for no protection and vertically dripping water, while IP03 provides no protection and spraying water (up to 60°).
IP01 provides no protection against solid objects 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 0 with second-digit (liquid) level 1.
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.

The exact difference (IP01 vs IP03)
Solid protection
IP01
Level 0 — No Protection
IP03
Level 0 — No Protection
Both IP01 and IP03 share the same solid protection: No Protection.
Liquid protection
IP01
Level 1 — Vertically Dripping Water
IP03
Level 3 — Spraying Water (up to 60°)
IP01 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP03 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP03 provides 2 levels more liquid protection.

Recommendation
IP03 offers higher overall protection than IP01. Choose IP03 for harsher environments; IP01 may suffice for milder conditions and can be more cost-effective.
