IP24 vs IP46
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP24 and IP46 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 4) and liquid protection (level 4 vs 6). IP24 is rated for > 12.5 mm — finger and splashing water (all directions), while IP46 provides > 1 mm — small wires and powerful water jets (12.5 mm nozzle).
With IP24, an enclosure receives protection against solid objects larger than 12.5 mm and protection against splashing water. Water splashed against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 4.
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.

The exact difference (IP24 vs IP46)
Solid protection
IP24
Level 2 — > 12.5 mm — Finger
IP46
Level 4 — > 1 mm — Small Wires
IP24 provides "> 12.5 mm — Finger" (level 2), while IP46 provides "> 1 mm — Small Wires" (level 4). IP46 is 2 levels higher.
Liquid protection
IP24
Level 4 — Splashing Water (all directions)
IP46
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP24 handles 50–100 kPa (Splashing Water (all directions)), while IP46 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP46 provides 2 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP46 offers higher overall protection than IP24. Choose IP46 for harsher environments; IP24 may suffice for milder conditions and can be more cost-effective.
