Thomas Betts E989R-1-HD Junction Box Nema 4 4X 12x12x6

Product Description

The THOMAS BETTS E989R-1-HD is a thermoplastic junction box enclosure rated NEMA 4 and 4X, designed to protect electrical connections and components in demanding indoor and outdoor environments. Measuring 12 inches wide by 12 inches high by 6 inches deep and weighing 9.5 pounds, this enclosure provides a corrosion-resistant housing suitable for wet and washdown locations. The flat screw cover secures with stainless steel screws, and a foam-in-place gasket delivers a reliable environmental seal. It is installed by licensed electricians across commercial and industrial applications where moisture, dust, and corrosive atmospheres are a concern.

This enclosure is suited for residential, commercial, and light industrial electrical installations requiring NEMA 4 or 4X rated protection. Typical applications include junction and pull box installations in mechanical rooms, rooftop equipment areas, food processing environments, and other locations exposed to hose-directed water or corrosive conditions. The thermoplastic construction resists rust and chemical degradation, making it a practical choice where metal enclosures would be prone to corrosion over time.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize all circuits before opening or wiring the enclosure. Verify that all conduit entries are properly sealed with listed fittings to maintain the NEMA 4 4X rating. Do not overtighten the cover screws, as thermoplastic enclosures can crack under excessive torque.
