There is no such thing of NEMA Standard Size for Enclosures. The NEMA 250 standard provides construction and test requirements, but each developer or manufacturer designs its own enclosures.
An electrical enclosure is a cabinet or box that protects electrical or electronic equipment and prevents physical and electrical shocks. Enclosures are usually made from plastic, carbon fibers, composite materials, or such metals as steel, stainless steel, or aluminum. Enclosures are rated to surface painting/printing, designate protection against hazardous, non-hazardous, and other specific environmental conditions. Enclosures protect electrical equipment in diverse industrial, airborne, building, and utility applications. They may also shield equipment from electromagnetic and radio frequency interference, considering antennas have been well-installed for some wireless devices. Enclosures are often used to protect circuit breakers, industrial PCB main board, contactors, control panels, and switches. Plastic enclosures are widely applied for hand-held, key-fob, wall-mount, desk-top electrical devices or instruments.
By applying off-shelter enclosures, the developer or manufacturer enjoys the benefits of:
• Shorter lead time and no initial tooling charge.
• No extra charge for multi-color operation.
• Lower MOQ, small quantity order
• Cost-effective solution, lower unit price
