When an enclosure is configured with various components, it is essential to consider where the enclosure will be placed and how harsh the environment is so that it can properly protect the inside components from foreign substances. Choosing an enclosure with appropriate protection ratings is one of the most important things in the configuration process. There are several standards widely accepted in the manufacturing industry such as UL, NEMA, CSA or IEC classification. Mencom enclosures are listed with UL/NEMA rating and the infographic below illustrates what kinds of protections can be provided at each class and what the differences are between them.
