IP19K vs IP24
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP19K and IP24 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 2) and liquid protection (level 9K vs 4). IP19K is rated for > 50 mm — back of hand and high-pressure, high-temp water jets, while IP24 provides > 12.5 mm — finger and splashing water (all directions).
Under IEC 60529, IP19K specifies protection against solid objects larger than 50 mm and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. It is an IEC 60529 ingress protection code combining first-digit (solid) level 1 with second-digit (liquid) level 9K.
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 (IP19K vs IP24)
Solid protection
IP19K
Level 1 — > 50 mm — Back of Hand
IP24
Level 2 — > 12.5 mm — Finger
IP19K provides "> 50 mm — Back of Hand" (level 1), while IP24 provides "> 12.5 mm — Finger" (level 2). IP24 is 1 level higher.
Liquid protection
IP19K
Level 9 — High-Pressure, High-Temp Water Jets
IP24
Level 4 — Splashing Water (all directions)
IP19K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP24 handles 50–100 kPa (Splashing Water (all directions)). IP19K provides 5 levels more liquid protection.

No direct NEMA equivalent.
Recommendation
IP19K offers higher overall protection than IP24. Choose IP19K for harsher environments; IP24 may suffice for milder conditions and can be more cost-effective.
