IP30 vs IP39K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IP39K are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 0 vs 9K). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IP39K provides > 2.5 mm — tool / wire and high-pressure, high-temp water jets.
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.
IP39K is an ingress protection code that ensures protection against solid objects larger than 2.5 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 3 with second-digit (liquid) level 9K.

The exact difference (IP30 vs IP39K)
Solid protection
IP30
Level 3 — > 2.5 mm — Tool / Wire
IP39K
Level 3 — > 2.5 mm — Tool / Wire
Both IP30 and IP39K share the same solid protection: > 2.5 mm — Tool / Wire.
Liquid protection
IP30
Level 0 — No Protection
IP39K
Level 9 — High-Pressure, High-Temp Water Jets
IP30 provides "No Protection" (level 0), while IP39K provides "High-Pressure, High-Temp Water Jets" (level 9). IP39K is 9 levels higher.

Recommendation
IP39K offers higher overall protection than IP30. Choose IP39K for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
