Approximate Conversions of NEMA Enclosure Types to IP Classification Designations

NEMA ratings can only be approximately compared to those of the IP system. Other factors such as corrosion protection and construction details are involved in the NEMA system; please refer to each organization’s official documentation for details.

The table provides a near equivalent guide for converting from NEMA Enclosure Type Numbers to IEC Enclosure Classification Designations.

This information is provided as a guide only for comparing NEMA enclosure types to IEC designations. The table should not be used to convert from IEC classifications to NEMA Types and the NEMA to IEC conversion should be verified by test.
