IP54 vs IP48
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP54 and IP48 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 4) and liquid protection (level 4 vs 8). IP54 is rated for dust-protected and splashing water (all directions), while IP48 provides > 1 mm — small wires 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.
Engineered to deliver protection against solid objects larger than 1.0 mm and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. Classified as IEC 60529 ingress protection code IP48, it pairs solid level 4 with liquid level 8.

The exact difference (IP54 vs IP48)
Solid protection
IP54
Level 5 — Dust-Protected
IP48
Level 4 — > 1 mm — Small Wires
IP54 provides "Dust-Protected" (level 5), while IP48 provides "> 1 mm — Small Wires" (level 4). IP54 is 1 level higher.
Liquid protection
IP54
Level 4 — Splashing Water (all directions)
IP48
Level 8 — Continuous Immersion (manufacturer-specified)
IP54 handles 50–100 kPa (Splashing Water (all directions)), while IP48 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP48 provides 4 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP48 offers higher overall protection than IP54. Choose IP48 for harsher environments; IP54 may suffice for milder conditions and can be more cost-effective.
