IP02 vs IP45
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP02 and IP45 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 4) and liquid protection (level 2 vs 5). IP02 is rated for no protection and dripping water at 15° tilt, while IP45 provides > 1 mm — small wires and water jets (6.3 mm nozzle).
Engineered to deliver no protection against solid objects and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. Classified as IEC 60529 ingress protection code IP02, it pairs solid level 0 with liquid level 2.
IP45 protects against 1 mm solid objects and low-pressure water jets (6.3 mm nozzle, 30 kPa). A mid-range indoor/outdoor-covered rating for equipment that may be rinsed or hosed gently.

The exact difference (IP02 vs IP45)
Solid protection
IP02
Level 0 — No Protection
IP45
Level 4 — > 1 mm — Small Wires
IP02 provides "No Protection" (level 0), while IP45 provides "> 1 mm — Small Wires" (level 4). IP45 is 4 levels higher.
Liquid protection
IP02
Level 2 — Dripping Water at 15° Tilt
IP45
Level 5 — Water Jets (6.3 mm nozzle)
IP02 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP45 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP45 provides 3 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP45 offers higher overall protection than IP02. Choose IP45 for harsher environments; IP02 may suffice for milder conditions and can be more cost-effective.
