IP55 vs IP60
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP55 and IP60 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6) and liquid protection (level 5 vs 0). IP55 is rated for dust-protected and water jets (6.3 mm nozzle), while IP60 provides dust-tight and no protection.
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.
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.

Recommendation
IP55 offers higher overall protection than IP60. Choose IP55 for harsher environments; IP60 may suffice for milder conditions and can be more cost-effective.
