IP52 vs IP55
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP52 and IP55 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 2 vs 5). IP52 is rated for dust-protected and dripping water at 15° tilt, while IP55 provides dust-protected and water jets (6.3 mm nozzle).
IP52 is an ingress protection code that ensures dust-protected (limited ingress, no harmful deposit) and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 5 with second-digit (liquid) level 2.
IP55 is dust-protected and resists low-pressure water jets (6.3 mm nozzle, 30 kPa). A popular industrial rating for equipment exposed to dust and directed water spray but not immersion.

The exact difference (IP52 vs IP55)
Solid protection
IP52
Level 5 — Dust-Protected
IP55
Level 5 — Dust-Protected
Both IP52 and IP55 share the same solid protection: Dust-Protected.
Liquid protection
IP52
Level 2 — Dripping Water at 15° Tilt
IP55
Level 5 — Water Jets (6.3 mm nozzle)
IP52 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP55 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP55 provides 3 levels more liquid protection.

Recommendation
IP55 offers higher overall protection than IP52. Choose IP55 for harsher environments; IP52 may suffice for milder conditions and can be more cost-effective.
