Thomas Betts E989NNR Junction Box Nema 4 4X 6P Pvc

Product Description

The THOMAS BETTS E989NNR is a polyvinylchloride (PVC) junction box electrical enclosure rated for NEMA 4, 4X, and 6P environments. It measures 4 inches wide, 4 inches high, and 6 inches deep, providing a compact footprint with adequate interior volume for terminal blocks, wire splices, or small control components. The enclosure features a screw flat cover and ships with a foam-in-place gasket and stainless steel screws included. Built from PVC, it delivers inherent corrosion resistance without additional coatings or treatments. Electricians and instrumentation technicians install this enclosure in locations where moisture ingress, washdown exposure, or corrosive atmospheres are a concern.

This enclosure is suited for both indoor and outdoor applications where watertight and corrosion-resistant protection is required. Typical installations include wet-location junction points, chemical processing areas, food and beverage facilities, marine environments, and outdoor electrical distribution points. The NEMA 4X and 6P ratings make it appropriate for areas subject to hose-directed water or temporary submersion. Its PVC construction makes it a practical choice over steel enclosures in corrosive or salt-air environments where long-term finish integrity matters.

Key Features

• NEMA 4, 4X, and 6P rated for watertight and corrosion-resistant protection
• Polyvinylchloride construction resists corrosion without surface coatings
• Screw flat cover for secure, tool-accessible closure
• Foam-in-place gasket included for reliable environmental sealing
• Stainless steel screws included to maintain corrosion resistance at all fastener points
• UL Listed under File E11461

Compatibility

Designed as an OEM-style replacement or new-installation junction box enclosure for wet-location and corrosive-environment electrical applications requiring NEMA 4, 4X, or 6P compliance.

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 opening or wiring the enclosure. Verify that all conduit entries are sealed with appropriate fittings rated for the NEMA environment to maintain the listed ingress protection. Do not use fasteners or hardware that would compromise the corrosion-resistance rating at the cover interface.
