Eaton Crouse-Hinds NCD31 Enclosure - Class I Division 2

The NCD31 is a compact 1" trade-size dead-end enclosure for a single control circuit. This feature reduces panel footprint and wiring length, accelerating installation in tight electrical rooms and crowded plants. The result is lower labor costs and easier future expansion for machine control panels in chemical plants and refineries. The NEC/CEC compliance paired with Class I, Division 2 rating and NEMA protections 3, 4X, 7, 12 delivers consistent safety and protection, helping teams pass regulatory audits and minimize risk in hazardous environments. With dimensions of 3.81 in depth, 7.25 in height, 4.38 in width and a weight of 2.59 lb, the enclosure is easy to handle, mount, and retrofit into existing stations, supporting flexible project execution. The must-be-used-with MSR1 or MSR2 suffix requirement ensures correct device compatibility and accurate documentation, reducing field errors during assembly. A single-circuit, dead-end style design simplifies wiring, reduces spare part needs, and speeds maintenance in high-demand automation applications. This enclosure supports straightforward replacement of control boards, scalable panel layouts, and reliable operation in demanding industrial settings.
