IP58 vs IP03
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP03 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 0) and liquid protection (level 8 vs 3). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP03 provides no protection and spraying water (up to 60°).
IP58 is dust-protected and rated for continuous immersion in water under manufacturer-specified conditions. A niche rating for equipment that must operate submerged while allowing limited dust ingress.
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 (IP58 vs IP03)
Solid protection
IP58
Level 5 — Dust-Protected
IP03
Level 0 — No Protection
IP58 provides "Dust-Protected" (level 5), while IP03 provides "No Protection" (level 0). IP58 is 5 levels higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP03
Level 3 — Spraying Water (up to 60°)
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP03 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP58 provides 5 levels more liquid protection.

Recommendation
IP58 offers higher overall protection than IP03. Choose IP58 for harsher environments; IP03 may suffice for milder conditions and can be more cost-effective.
