IP19K vs IP30
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP19K and IP30 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 3) and liquid protection (level 9K vs 0). IP19K is rated for > 50 mm — back of hand and high-pressure, high-temp water jets, while IP30 provides > 2.5 mm — tool / wire and no protection.
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.
IP30 protects against tools and 2.5 mm solid objects but offers no water protection. A basic indoor rating for equipment in dry, low-dust environments where only tool-access protection is required.

The exact difference (IP19K vs IP30)
Solid protection
IP19K
Level 1 — > 50 mm — Back of Hand
IP30
Level 3 — > 2.5 mm — Tool / Wire
IP19K provides "> 50 mm — Back of Hand" (level 1), while IP30 provides "> 2.5 mm — Tool / Wire" (level 3). IP30 is 2 levels higher.
Liquid protection
IP19K
Level 9 — High-Pressure, High-Temp Water Jets
IP30
Level 0 — No Protection
IP19K provides "High-Pressure, High-Temp Water Jets" (level 9), while IP30 provides "No Protection" (level 0). IP19K is 9 levels higher.

Recommendation
IP19K offers higher overall protection than IP30. Choose IP19K for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
