Thomas Betts NJ12126 Polycarbonate Enclosure 12x12x6

Product Description

The THOMAS BETTS NJ12126 is a standard electrical enclosure made from impact-resistant polycarbonate, designed to house and protect electrical components in a wide range of indoor and outdoor installations. Measuring 12 inches wide by 12 inches high by 6 inches deep and weighing 7 pounds, it provides a sturdy, weatherproof housing suitable for control panels, junction boxes, and similar electrical assemblies. The enclosure carries a multi-rating of NEMA 1, 2, 3, 3S, 3SX, 3X, 4, and 4X, covering applications from general-purpose indoor use through corrosion-resistant and outdoor watertight service. Licensed electricians and electrical contractors are the primary installers.

This enclosure suits residential, commercial, and light industrial applications where a compact, corrosion-resistant housing is required. The polycarbonate construction makes it appropriate for environments where metal enclosures would corrode or where lighter weight is advantageous. Its NEMA 4X rating qualifies it for wet or wash-down locations. The hinged flat cover with captive screws and swing panels supports straightforward access during installation and maintenance without the risk of losing hardware.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits before mounting components inside the enclosure or making any wiring connections. Verify the selected mounting surface can support the enclosure weight and that all conduit entries are properly sealed to maintain the NEMA rating. Do not over-tighten the captive cover screws, as polycarbonate housings can crack under excessive fastener torque.
