IP54 vs IP28
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP54 and IP28 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 2) and liquid protection (level 4 vs 8). IP54 is rated for dust-protected and splashing water (all directions), while IP28 provides > 12.5 mm — finger and continuous immersion (manufacturer-specified).
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.
Specified under IEC 60529, IP28 denotes protection against solid objects larger than 12.5 mm and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 8.

The exact difference (IP54 vs IP28)
Solid protection
IP54
Level 5 — Dust-Protected
IP28
Level 2 — > 12.5 mm — Finger
IP54 provides "Dust-Protected" (level 5), while IP28 provides "> 12.5 mm — Finger" (level 2). IP54 is 3 levels higher.
Liquid protection
IP54
Level 4 — Splashing Water (all directions)
IP28
Level 8 — Continuous Immersion (manufacturer-specified)
IP54 handles 50–100 kPa (Splashing Water (all directions)), while IP28 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP28 provides 4 levels more liquid protection.

No direct NEMA equivalent.
Recommendation
IP28 offers higher overall protection than IP54. Choose IP28 for harsher environments; IP54 may suffice for milder conditions and can be more cost-effective.
