Thomas Betts NJ864 Polycarbonate Enclosure Nema 4X 6x8x4 in

Product Description

The THOMAS BETTS NJ864 is a standard polycarbonate electrical enclosure designed to house and protect electrical components in demanding environments. Measuring 6 inches wide, 8 inches high, and 4 inches deep, this enclosure carries a multi-NEMA rating that covers indoor and outdoor applications including NEMA 4X, making it suitable for wet and corrosive locations. The flat-hinged cover with captive screws allows for secure, repeatable access. Licensed electricians and industrial maintenance technicians are the primary installers. The impact-resistant polycarbonate construction provides a non-metallic housing option where corrosion resistance or electrical isolation is a priority.

This enclosure fits residential, commercial, and light industrial electrical installations where a compact, multi-rated housing is required. Its NEMA 1, 2, 3, 3S, 3SX, 3X, 4, and 4X ratings make it appropriate for control panels, junction boxes, and instrumentation protection in both indoor and outdoor settings. The 6 x 8 x 4 inch footprint suits small to mid-size control assemblies. Swing panels are included, allowing flexible interior layout for DIN rail, terminal blocks, or other mounting hardware.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and applicable local codes. De-energize all circuits before opening or modifying the enclosure. Verify that all conduit entries and sealing fittings are appropriate for the NEMA rating required at the installation site. Do not over-tighten the captive cover screws, as polycarbonate threads can be damaged by excessive torque.
