IP30 vs IP57
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IP57 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 5) and liquid protection (level 0 vs 7). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IP57 provides dust-protected and temporary immersion (up to 1 m).
IP30 protects against tools and 2.5 mm solid objects but offers no water protection. A basic indoor rating for equipment in dry, low-dust environments where only tool-access protection is required.
IP57 is dust-protected and tolerates temporary immersion up to 1 m for 30 minutes. Useful for portable devices that may be dropped in shallow water.

Recommendation
IP57 offers higher overall protection than IP30. Choose IP57 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
