IP58 vs IP24
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP24 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 2) and liquid protection (level 8 vs 4). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP24 provides > 12.5 mm — finger and splashing water (all directions).
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.
With IP24, an enclosure receives protection against solid objects larger than 12.5 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 2 with second-digit (liquid) level 4.

The exact difference (IP58 vs IP24)
Solid protection
IP58
Level 5 — Dust-Protected
IP24
Level 2 — > 12.5 mm — Finger
IP58 provides "Dust-Protected" (level 5), while IP24 provides "> 12.5 mm — Finger" (level 2). IP58 is 3 levels higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP24
Level 4 — Splashing Water (all directions)
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP24 handles 50–100 kPa (Splashing Water (all directions)). IP58 provides 4 levels more liquid protection.

No direct NEMA equivalent.
Recommendation
IP58 offers higher overall protection than IP24. Choose IP58 for harsher environments; IP24 may suffice for milder conditions and can be more cost-effective.
