IP56 vs IP41
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP56 and IP41 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 4) and liquid protection (level 6 vs 1). IP56 is rated for dust-protected and powerful water jets (12.5 mm nozzle), while IP41 provides > 1 mm — small wires and vertically dripping water.
IP56 is dust-protected and resists powerful water jets (12.5 mm nozzle, 100 kPa). Suited to outdoor equipment subjected to heavy rain or hose-directed water.
Under IEC 60529, IP41 specifies protection against solid objects larger than 1.0 mm 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 4 with second-digit (liquid) level 1.

The exact difference (IP56 vs IP41)
Solid protection
IP56
Level 5 — Dust-Protected
IP41
Level 4 — > 1 mm — Small Wires
IP56 provides "Dust-Protected" (level 5), while IP41 provides "> 1 mm — Small Wires" (level 4). IP56 is 1 level higher.
Liquid protection
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP41
Level 1 — Vertically Dripping Water
IP56 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP41 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP56 provides 5 levels more liquid protection.

No direct NEMA equivalent.
Recommendation
IP56 offers higher overall protection than IP41. Choose IP56 for harsher environments; IP41 may suffice for milder conditions and can be more cost-effective.
