IP Enclosures

IP Enclosure Ratings & Standards

At Nema Enclosures, we strictly adhere to the International Electrotechnical Commission standardized international (or Ingress) Protection Code, which defines an enclosure’s rating. The IP Code reflects the degree of protection as “IP” followed by two numbers. The first digit ranges from 0 to 6, reflecting in degrees the level of protection against particles, and protection to others from enclosed hazards. The second digit ranges from 0 to 8 and indicates the extent of protection against water. Because our enclosures stringently observe these guidelines, you can expect superior IP enclosures that are available in a number of materials and types, and can be enhanced by our value added services.

Refer to the chart below for the relative ingress protection ratings of electrical enclosures:

Ingress Protection (IP) codes for electrical enclosures in Class 1/DIV 2 and non-hazardous locations

An IP (Ingress Protection) rating is used mainly by buyers in Europe to specify the extent of protection an electrical enclosure has against environmental conditions. Ingress Protection Standards were established by the International Electromechanical Commission (IEC), a worldwide organization for standardization. The object of the IEC is to promote International cooperation on all questions concerning standardization in the electrical and electronic fields. The IEC collaborates closely with the International Organization for Standards (ISO).
