IP45 vs IP60
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP45 and IP60 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 6) and liquid protection (level 5 vs 0). IP45 is rated for > 1 mm — small wires and water jets (6.3 mm nozzle), while IP60 provides dust-tight and no protection.
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.
IP60 is dust-tight with no water protection. Used for indoor equipment in very dusty environments that stays completely dry — dust exclusion without any moisture tolerance.

The exact difference (IP45 vs IP60)
Solid protection
IP45
Level 4 — > 1 mm — Small Wires
IP60
Level 6 — Dust-Tight
IP45 provides "> 1 mm — Small Wires" (level 4), while IP60 provides "Dust-Tight" (level 6). IP60 is 2 levels higher.
Liquid protection
IP45
Level 5 — Water Jets (6.3 mm nozzle)
IP60
Level 0 — No Protection
IP45 provides "Water Jets (6.3 mm nozzle)" (level 5), while IP60 provides "No Protection" (level 0). IP45 is 5 levels higher.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP45 offers higher overall protection than IP60. Choose IP45 for harsher environments; IP60 may suffice for milder conditions and can be more cost-effective.
