IP35 vs IP53
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP35 and IP53 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 5) and liquid protection (level 5 vs 3). IP35 is rated for > 2.5 mm — tool / wire and water jets (6.3 mm nozzle), while IP53 provides dust-protected and spraying water (up to 60°).
Built to withstand protection against solid objects larger than 2.5 mm and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP35, it pairs solid level 3 with liquid level 5.
Built to withstand dust-protected (limited ingress, no harmful deposit) and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP53, it pairs solid level 5 with liquid level 3.

The exact difference (IP35 vs IP53)
Solid protection
IP35
Level 3 — > 2.5 mm — Tool / Wire
IP53
Level 5 — Dust-Protected
IP35 provides "> 2.5 mm — Tool / Wire" (level 3), while IP53 provides "Dust-Protected" (level 5). IP53 is 2 levels higher.
Liquid protection
IP35
Level 5 — Water Jets (6.3 mm nozzle)
IP53
Level 3 — Spraying Water (up to 60°)
IP35 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP53 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP35 provides 2 levels more liquid protection.

No direct NEMA equivalent.
Recommendation
IP35 and IP53 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
