IP54 vs IP61
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP54 and IP61 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6) and liquid protection (level 4 vs 1). IP54 is rated for dust-protected and splashing water (all directions), while IP61 provides dust-tight and vertically dripping water.
IP54 is dust-protected (limited ingress, no harmful deposit) and resists splashing water from any direction. A versatile rating for industrial and outdoor-covered equipment in dusty, damp environments.
IP61 is an ingress protection code that ensures dust-tight (no ingress of dust) and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 6 with second-digit (liquid) level 1.

The exact difference (IP54 vs IP61)
Solid protection
IP54
Level 5 — Dust-Protected
IP61
Level 6 — Dust-Tight
IP54 provides "Dust-Protected" (level 5), while IP61 provides "Dust-Tight" (level 6). IP61 is 1 level higher.
Liquid protection
IP54
Level 4 — Splashing Water (all directions)
IP61
Level 1 — Vertically Dripping Water
IP54 handles 50–100 kPa (Splashing Water (all directions)), while IP61 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP54 provides 3 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP54 offers higher overall protection than IP61. Choose IP54 for harsher environments; IP61 may suffice for milder conditions and can be more cost-effective.
