Thomas Betts NS12106 Polycarbonate Enclosure 10x12x6 Nema 4X

Product Description

The THOMAS BETTS NS12106 is a standard polycarbonate electrical enclosure rated for NEMA 1, 2, 3, 3S, 3SX, 3X, 4, and 4X environments. It measures 10 inches wide, 12 inches high, and 6 inches deep, providing a compact but capable housing for electrical controls, terminal blocks, and similar components. The enclosure features a screw flat cover with captive cover screws for secure closure and includes hinges and swing panels for convenient access. Its impact-resistant polycarbonate construction handles both indoor and outdoor installations. Licensed electricians and controls technicians typically specify this enclosure for protecting sensitive electrical components in industrial, commercial, and utility applications.

This enclosure is suited for residential, commercial, and light industrial installations where moisture, dust, or corrosive atmospheres require a sealed housing. The broad NEMA rating range — spanning NEMA 1 through 4X — makes it a flexible choice for panel builders and field technicians working across multiple environment types. Its polycarbonate body resists corrosion in wet or chemically exposed locations, and the flat cover profile keeps the installed footprint low in tight equipment rooms or on wall-mounted control surfaces.

Compatibility

Designed as an OEM-style standard electrical enclosure suitable for mounting electrical controls, terminal strips, and related components in applications requiring NEMA 4X or lower environmental protection ratings.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize all circuits before opening or mounting the enclosure. Verify that conduit entries and fittings maintain the intended NEMA rating after field modification. Do not exceed the enclosure volume capacity when filling with wiring or components, as adequate air circulation is required for heat dissipation.
