IP00 vs IP03
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP00 and IP03 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 0 vs 3). IP00 is rated for no protection and no protection, while IP03 provides no protection and spraying water (up to 60°).
IP00 offers no protection against solid objects or moisture. It is suitable only for indoor, climate-controlled environments where the equipment is fully enclosed within another protective housing.
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 (IP00 vs IP03)
Solid protection
IP00
Level 0 — No Protection
IP03
Level 0 — No Protection
Both IP00 and IP03 share the same solid protection: No Protection.
Liquid protection
IP00
Level 0 — No Protection
IP03
Level 3 — Spraying Water (up to 60°)
IP00 provides "No Protection" (level 0), while IP03 provides "Spraying Water (up to 60°)" (level 3). IP03 is 3 levels higher.

Recommendation
IP03 offers higher overall protection than IP00. Choose IP03 for harsher environments; IP00 may suffice for milder conditions and can be more cost-effective.
