Thomas Betts C2016A4 Thermoplastic Enclosure Nema 4X

Product Description

The THOMAS BETTS C2016A4 is a standard thermoplastic electrical enclosure rated for NEMA 1, 2, 3, 3S, 3SX, 3X, 4, 4X, and 12 environments. It measures 16.5 inches wide and weighs 15 pounds. The enclosure features a hinged flat cover secured with stainless steel screws and includes brass screw inserts, mounting feet, mounting hardware, and non-metallic hinges — all shipped as part of the assembly. It is listed to cULus E108856 and CSA File LR31146, making it suitable for installations where independent certification is required. Electricians and industrial control panel builders install this enclosure to house electrical components in locations that require protection from dust, water, and corrosive environments.

This enclosure is appropriate for a wide range of residential, commercial, and light industrial applications. Its NEMA 4X rating makes it suitable for indoor and outdoor installations where hosedown, rain, or corrosion exposure is a concern. The thermoplastic construction resists rust and reduces weight compared to steel alternatives. It is commonly used to house control boards, terminal blocks, disconnect switches, and similar components in mechanical rooms, rooftop installations, and outdoor equipment panels.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. Disconnect and lock out all power to the circuit before mounting or wiring inside the enclosure. Verify that conduit entry points are sealed appropriately to maintain the enclosure NEMA rating after installation. Do not modify the enclosure body in ways that compromise its rated ingress protection.
