IP46 vs IP54
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP46 and IP54 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 5) and liquid protection (level 6 vs 4). IP46 is rated for > 1 mm — small wires and powerful water jets (12.5 mm nozzle), while IP54 provides dust-protected and splashing water (all directions).
Specified under IEC 60529, IP46 denotes protection against solid objects larger than 1.0 mm and protection against powerful water jets. Water projected in powerful jets by a 12.5 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 4 with second-digit (liquid) level 6.
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 (IP46 vs IP54)
Solid protection
IP46
Level 4 — > 1 mm — Small Wires
IP54
Level 5 — Dust-Protected
IP46 provides "> 1 mm — Small Wires" (level 4), while IP54 provides "Dust-Protected" (level 5). IP54 is 1 level higher.
Liquid protection
IP46
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP54
Level 4 — Splashing Water (all directions)
IP46 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP54 handles 50–100 kPa (Splashing Water (all directions)). IP46 provides 2 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP46 offers higher overall protection than IP54. Choose IP46 for harsher environments; IP54 may suffice for milder conditions and can be more cost-effective.
