IP03 vs IP50
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP03 and IP50 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 5) and liquid protection (level 3 vs 0). IP03 is rated for no protection and spraying water (up to 60°), while IP50 provides dust-protected and no protection.
Designed for environments requiring no protection against solid objects and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects., IP03 is an IEC 60529 code combining solid level 0 with liquid level 3.
Under IEC 60529, IP50 specifies dust-protected (limited ingress, no harmful deposit) and no protection against water. It is an IEC 60529 ingress protection code combining first-digit (solid) level 5 with second-digit (liquid) level 0.

Liquid protection
IP03
Level 3 — Spraying Water (up to 60°)
IP50
Level 0 — No Protection

Recommendation
IP50 offers higher overall protection than IP03. Choose IP50 for harsher environments; IP03 may suffice for milder conditions and can be more cost-effective.
