Thomas Betts NV664 Polycarbonate Enclosure 6x6x4 Nema 4X

Product Description

The THOMAS BETTS NV664 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, 6 inches high, and 4 inches deep, it provides a compact yet functional footprint for control boards, terminal blocks, and similar gear. The clear polycarbonate construction allows visual inspection of interior components without opening the enclosure. A screw flat cover with captive fasteners keeps the lid secure during service. Licensed electricians and instrumentation technicians typically install this enclosure in panel rooms, equipment skids, and light industrial environments.

The NV664 is rated for NEMA 1, 2, 3, 3S, 3SX, 3X, 4, and 4X environments, making it suitable for both dry indoor locations and wet or washdown-exposure areas. Its impact-resistant polycarbonate body holds up to physical abuse on job sites. The enclosure ships with captive cover screws, hinges, and swing panels included. Residential, commercial, and light industrial electrical work are all common applications. It is a practical choice wherever a compact, corrosion-resistant, transparent enclosure is needed to comply with NEC installation requirements.

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 or wiring inside the enclosure. Verify that the selected mounting surface and conduit entries are appropriate for the NEMA rating required by the application. Avoid drilling or cutting the polycarbonate body with tools or methods that could crack the material — use a step bit or hole saw rated for plastics.
