IP08 vs IP33
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP08 and IP33 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 8 vs 3). IP08 is rated for no protection and continuous immersion (manufacturer-specified), while IP33 provides > 2.5 mm — tool / wire and spraying water (up to 60°).
Built to withstand no protection against solid objects and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. Classified as IEC 60529 ingress protection code IP08, it pairs solid level 0 with liquid level 8.
IP33 protects against tools and 2.5 mm objects plus spraying water up to 60° from vertical. A practical rating for indoor equipment subject to light spray or for sheltered outdoor fixtures.

The exact difference (IP08 vs IP33)
Solid protection
IP08
Level 0 — No Protection
IP33
Level 3 — > 2.5 mm — Tool / Wire
IP08 provides "No Protection" (level 0), while IP33 provides "> 2.5 mm — Tool / Wire" (level 3). IP33 is 3 levels higher.
Liquid protection
IP08
Level 8 — Continuous Immersion (manufacturer-specified)
IP33
Level 3 — Spraying Water (up to 60°)
IP08 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP33 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP08 provides 5 levels more liquid protection.

Recommendation
IP08 offers higher overall protection than IP33. Choose IP08 for harsher environments; IP33 may suffice for milder conditions and can be more cost-effective.
