Thomas Betts NS664 Polycarbonate Enclosure 6x6x4 Nema 4X

Product Description

The THOMAS BETTS NS664 is a standard polycarbonate electrical enclosure designed to house and protect electrical components in a wide range of indoor and outdoor installations. Measuring 6 inches wide by 6 inches high by 4 inches deep, this enclosure features a screw flat cover and is constructed from impact-resistant polycarbonate. It carries cULus and UL 50 listings and meets NEMA ratings 1, 2, 3, 3S, 3SX, 3X, 4, 4X, and 12, making it suitable for environments requiring protection from dust, water, and corrosion. Electricians and controls technicians install this enclosure for panel boards, junction boxes, and instrument housings.

The NS664 is suited for both residential and light commercial applications where a compact, multi-rated enclosure is needed. Its NEMA 4X and 3X ratings make it appropriate for wet or washdown-area installations, including light industrial and commercial settings. The polycarbonate construction offers corrosion resistance without the weight of metal alternatives, which is useful in installations where the enclosure will be exposed to chemicals or moisture over time.
