Electrical Enclosure Ratings: IP
IP55 to IP69K
Electrical enclosure protection ratings — NEMA 250-2020 types (1 through 13 with variants) and IEC 60529 IP codes (IP20 through IP69K); includes protection descriptions, indoor/outdoor use, IP equivalents, corrosion resistance, hazardous location class/group, typical materials, and typical applications
