IP17 vs IP58
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP17 and IP58 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 5) and liquid protection (level 7 vs 8). IP17 is rated for > 50 mm — back of hand and temporary immersion (up to 1 m), while IP58 provides dust-protected and continuous immersion (manufacturer-specified).
Built to withstand protection against solid objects larger than 50 mm and protection against the effects of temporary immersion in water. Ingress of water in quantities causing harmful effects shall not be possible.. Classified as IEC 60529 ingress protection code IP17, it pairs solid level 1 with liquid level 7.
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.

The exact difference (IP17 vs IP58)
Solid protection
IP17
Level 1 — > 50 mm — Back of Hand
IP58
Level 5 — Dust-Protected
IP17 provides "> 50 mm — Back of Hand" (level 1), while IP58 provides "Dust-Protected" (level 5). IP58 is 4 levels higher.
Liquid protection
IP17
Level 7 — Temporary Immersion (up to 1 m)
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP17 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP58 provides 1 level more liquid protection.

Recommendation
IP58 offers higher overall protection than IP17. Choose IP58 for harsher environments; IP17 may suffice for milder conditions and can be more cost-effective.
