IP05 vs IP24
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP24 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2) and liquid protection (level 5 vs 4). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP24 provides > 12.5 mm — finger and splashing water (all directions).
Under IEC 60529, IP05 specifies no protection against solid objects and protection against water jets. Water projected by a 6.3 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 0 with second-digit (liquid) level 5.
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.

The exact difference (IP05 vs IP24)
Solid protection
IP05
Level 0 — No Protection
IP24
Level 2 — > 12.5 mm — Finger
IP05 provides "No Protection" (level 0), while IP24 provides "> 12.5 mm — Finger" (level 2). IP24 is 2 levels higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP24
Level 4 — Splashing Water (all directions)
IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP24 handles 50–100 kPa (Splashing Water (all directions)). IP05 provides 1 level more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP24 offers higher overall protection than IP05. Choose IP24 for harsher environments; IP05 may suffice for milder conditions and can be more cost-effective.
