Product Description

The THOMAS BETTS C2420A4 is a standard thermoplastic electrical enclosure rated for NEMA 1, 2, 3, 3S, 3SX, 3X, 4, 4X, and 12 environments. It features a hinged flat cover and measures 20.5 inches wide, providing a spacious interior for housing electrical controls, terminal blocks, and related components. The enclosure ships with brass screw inserts, mounting feet, mounting hardware, non-metallic hinges, and stainless steel screws included. It is listed under cULus E108856 and CSA File LR31146. Licensed electricians and industrial maintenance technicians are the primary installers for this type of enclosure.

This enclosure is suited for both indoor and outdoor applications where protection against dust, dirt, rain, sleet, and splashing water is required. The NEMA 4X rating makes it appropriate for corrosive or washdown environments. Typical installations include industrial control panels, pump stations, irrigation controls, and light commercial electrical distribution assemblies where a durable, non-metallic housing is preferred over steel.
