Thomas Betts NC12126 Polycarbonate Enclosure 12x12x6 Nema 4X

Product Description

The THOMAS BETTS NC12126 is a standard polycarbonate electrical enclosure rated for NEMA 1, 2, 3, 3S, 3SX, 3X, 4, and 4X environments. Measuring 12 inches wide by 12 inches high by 6 inches deep, it provides a clear hinged flat cover with captive cover screws and swing panels for convenient access during service. The polycarbonate construction delivers impact resistance along with transparency, allowing visual inspection of internal components without opening the enclosure. Weighing 6.58 pounds, it suits wall-mount applications where a lightweight yet durable housing is required. Electricians and controls technicians install this enclosure to protect terminal blocks, relays, PLCs, and other low-voltage control components in both indoor and select outdoor settings.

This enclosure is appropriate for residential and light commercial electrical and control applications where multi-rating NEMA protection is needed. The NEMA 4X rating makes it suitable for locations exposed to washdowns, corrosive atmospheres, or moisture ingress. The clear cover aids in troubleshooting and status verification without removing fasteners. Typical installation scenarios include control panels, instrumentation housings, junction boxes, and automation equipment enclosures in industrial, commercial, and utility environments.
