IP01 vs IP48
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP01 and IP48 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 4) and liquid protection (level 1 vs 8). IP01 is rated for no protection and vertically dripping water, while IP48 provides > 1 mm — small wires and continuous immersion (manufacturer-specified).
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.
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 (IP01 vs IP48)
Solid protection
IP01
Level 0 — No Protection
IP48
Level 4 — > 1 mm — Small Wires
IP01 provides "No Protection" (level 0), while IP48 provides "> 1 mm — Small Wires" (level 4). IP48 is 4 levels higher.
Liquid protection
IP01
Level 1 — Vertically Dripping Water
IP48
Level 8 — Continuous Immersion (manufacturer-specified)
IP01 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP48 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP48 provides 7 levels more liquid protection.

Recommendation
IP48 offers higher overall protection than IP01. Choose IP48 for harsher environments; IP01 may suffice for milder conditions and can be more cost-effective.
