IP00 vs IP43
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP00 and IP43 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 4) and liquid protection (level 0 vs 3). IP00 is rated for no protection and no protection, while IP43 provides > 1 mm — small wires and spraying water (up to 60°).
IP00 offers no protection against solid objects or moisture. It is suitable only for indoor, climate-controlled environments where the equipment is fully enclosed within another protective housing.
IP43 protects against 1 mm solid objects and spraying water up to 60° from vertical. A practical rating for sheltered equipment subject to light angled spray, such as covered outdoor fixtures.

Recommendation
IP43 offers higher overall protection than IP00. Choose IP43 for harsher environments; IP00 may suffice for milder conditions and can be more cost-effective.
