IP33 vs IP08
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP33 and IP08 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 0) and liquid protection (level 3 vs 8). IP33 is rated for > 2.5 mm — tool / wire and spraying water (up to 60°), while IP08 provides no protection and continuous immersion (manufacturer-specified).
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.
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.

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