IP11 vs IP54
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP11 and IP54 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 5) and liquid protection (level 1 vs 4). IP11 is rated for > 50 mm — back of hand and vertically dripping water, while IP54 provides dust-protected and splashing water (all directions).
Engineered to deliver protection against solid objects larger than 50 mm and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP11, it pairs solid level 1 with liquid level 1.
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.

The exact difference (IP11 vs IP54)
Solid protection
IP11
Level 1 — > 50 mm — Back of Hand
IP54
Level 5 — Dust-Protected
IP11 provides "> 50 mm — Back of Hand" (level 1), while IP54 provides "Dust-Protected" (level 5). IP54 is 4 levels higher.
Liquid protection
IP11
Level 1 — Vertically Dripping Water
IP54
Level 4 — Splashing Water (all directions)
IP11 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP54 handles 50–100 kPa (Splashing Water (all directions)). IP54 provides 3 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP54 offers higher overall protection than IP11. Choose IP54 for harsher environments; IP11 may suffice for milder conditions and can be more cost-effective.
