IP57 vs IP30
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP57 and IP30 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 3) and liquid protection (level 7 vs 0). IP57 is rated for dust-protected and temporary immersion (up to 1 m), while IP30 provides > 2.5 mm — tool / wire and no protection.
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.
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.

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.
