IP57 vs IP67
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP57 and IP67 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6). IP57 is rated for dust-protected and temporary immersion (up to 1 m), while IP67 provides dust-tight and temporary immersion (up to 1 m).
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.
IP67 is dust-tight and withstands temporary immersion in water up to 1 meter for 30 minutes. The go-to rating for outdoor and rugged devices that may be briefly submerged.

No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP57. Choose IP67 for harsher environments; IP57 may suffice for milder conditions and can be more cost-effective.
