Learn how differentiate the NEMA Ratings and IP numbers with the The International Electrotechnical Commission (IEC) 60529 Standard addresses Ingress (IP); this describes the degree of protection provided, not the enclosure itsel

What is an IP rating? IP (or "Ingress Protection") ratings are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:1989).

The IP rating system was established by the International Electromechanical Commission (IEC), a worldwide organization for standardization.

IEC Enclosure Classification Designations (IP Ratings) These IEC enclosure designations do not take into consideration the risk of explosions, damage of mechanical equipment, or environmental factors such as moisture; for that reason, NEMA enclosure types cannot directly be equated to IP ratings. IEC is a fully certified UL 508A manufacturer and can offer enclosures built to several UL Type environmental ratings.

IEC ratings are for more compact devices in the global market. IEC ratings react faster to overloads while NEMA ratings withstand short circuits. IEC devices are safe to the user, while NEMA devices require safety covers. Despite these significant differences, there are still some common misunderstandings that need to be debunked.

These IP codes are used to outline levels of protection for the application inside enclosures against solid and liquid. IP ratings are indicated by two digits, each with its own meaning, i.e.: IP 6 5 ( number 0 – 6 or letter X ) NEMA ratings define an electrical enclosure’s level of protection against ingress of water, solid objects, and corrosion resistance. What is an IP enclosure?

For example, the PW12 rating is less rigorous than the IP69K rating.
