Thomas Betts NV864 Polycarbonate Enclosure 6x8x4 Nema 4X

Product Description

The THOMAS BETTS NV864 is a standard polycarbonate electrical enclosure rated for NEMA 1, 2, 3, 3S, 3SX, 3X, 4, and 4X environments. It measures 6 inches wide, 8 inches high, and 4 inches deep, making it a compact solution for protecting electrical components, terminal blocks, and control devices in demanding service conditions. The clear polycarbonate body allows visual inspection of interior components without opening the enclosure. The screw flat cover is secured with captive cover screws and includes integrated hinges and swing panels. Licensed electricians and industrial maintenance technicians typically specify this enclosure for panel builds, junction boxes, and remote control stations.

This enclosure is suited for both residential and light commercial electrical installations where moisture, dust, or corrosion resistance is required. The broad NEMA rating range covers indoor and outdoor applications, including those with exposure to rain, sleet, windblown dust, and splashing water. Its impact-resistant polycarbonate construction makes it appropriate for environments where occasional physical contact or vibration is a concern. It ships as a single unit and is compatible with standard DIN rail and panel-mount hardware installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits before opening or modifying the enclosure interior. Verify that all conduit entries and knockouts are properly sealed to maintain the NEMA environmental rating after installation. Do not overtighten cover screws, as polycarbonate is subject to cracking under excessive fastener torque.
