Product Description

The THOMAS BETTS NC864 is a standard polycarbonate electrical enclosure designed to house and protect electrical components in commercial and industrial environments. Measuring 6 inches wide, 8 inches high, and 4 inches deep, this enclosure features a clear, hinged flat cover with captive cover screws and integrated swing panels for easy access during installation and maintenance. The polycarbonate construction delivers impact resistance along with multi-environment durability, meeting NEMA ratings 1, 2, 3, 3S, 3SX, 3X, 4, 4X, and 12. It is installed by licensed electricians and control systems technicians working on control panel builds, junction applications, and field instrument enclosures.

The NC864 suits a wide range of residential, commercial, and light industrial electrical applications where a compact, weather-resistant, and corrosion-resistant enclosure is required. Its NEMA 4X rating makes it suitable for indoor and outdoor use in locations exposed to windblown dust, rain, splashing water, and hose-directed water. The clear polycarbonate cover allows visual inspection of internal components without opening the enclosure, which is useful in control and monitoring installations.
