IP01 vs IP25
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP01 and IP25 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2) and liquid protection (level 1 vs 5). IP01 is rated for no protection and vertically dripping water, while IP25 provides > 12.5 mm — finger and water jets (6.3 mm nozzle).
IP01 provides no protection against solid objects 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 0 with second-digit (liquid) level 1.
IP25 is an ingress protection code that ensures protection against solid objects larger than 12.5 mm 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 2 with second-digit (liquid) level 5.

The exact difference (IP01 vs IP25)
Solid protection
IP01
Level 0 — No Protection
IP25
Level 2 — > 12.5 mm — Finger
IP01 provides "No Protection" (level 0), while IP25 provides "> 12.5 mm — Finger" (level 2). IP25 is 2 levels higher.
Liquid protection
IP01
Level 1 — Vertically Dripping Water
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP01 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP25 provides 4 levels more liquid protection.

Recommendation
IP25 offers higher overall protection than IP01. Choose IP25 for harsher environments; IP01 may suffice for milder conditions and can be more cost-effective.
