IP57 vs IP24
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP57 and IP24 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 2) and liquid protection (level 7 vs 4). IP57 is rated for dust-protected and temporary immersion (up to 1 m), while IP24 provides > 12.5 mm — finger and splashing water (all directions).
IP57 is dust-protected and tolerates temporary immersion up to 1 m for 30 minutes. Useful for portable devices that may be dropped in shallow water.
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 (IP57 vs IP24)
Solid protection
IP57
Level 5 — Dust-Protected
IP24
Level 2 — > 12.5 mm — Finger
IP57 provides "Dust-Protected" (level 5), while IP24 provides "> 12.5 mm — Finger" (level 2). IP57 is 3 levels higher.
Liquid protection
IP57
Level 7 — Temporary Immersion (up to 1 m)
IP24
Level 4 — Splashing Water (all directions)
IP57 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP24 handles 50–100 kPa (Splashing Water (all directions)). IP57 provides 3 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP57 offers higher overall protection than IP24. Choose IP57 for harsher environments; IP24 may suffice for milder conditions and can be more cost-effective.
