IP03 vs IP34
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP03 and IP34 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 3 vs 4). IP03 is rated for no protection and spraying water (up to 60°), while IP34 provides > 2.5 mm — tool / wire and splashing water (all directions).
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.
IP34 is an ingress protection code that ensures protection against solid objects larger than 2.5 mm 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 3 with second-digit (liquid) level 4.

The exact difference (IP03 vs IP34)
Solid protection
IP03
Level 0 — No Protection
IP34
Level 3 — > 2.5 mm — Tool / Wire
IP03 provides "No Protection" (level 0), while IP34 provides "> 2.5 mm — Tool / Wire" (level 3). IP34 is 3 levels higher.
Liquid protection
IP03
Level 3 — Spraying Water (up to 60°)
IP34
Level 4 — Splashing Water (all directions)
IP03 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP34 handles 50–100 kPa (Splashing Water (all directions)). IP34 provides 1 level more liquid protection.

Recommendation
IP34 offers higher overall protection than IP03. Choose IP34 for harsher environments; IP03 may suffice for milder conditions and can be more cost-effective.
