FAQs
To install the NCD34, ensure you select the MSR1 or MSR2 suffix version appropriate for your control devices. Mount the enclosure on a suitable surface, route conductors through listed glands, and secure the internal devices as per OEM wiring diagrams. Use the supplied hardware and sealants to maintain NEMA-rated protection during wiring and termination. This setup reduces retrofit time and improves field reliability in hazardous locations.
NCD34 supports 4 circuits in a dead-end configuration with a 1" trade size. It carries NEMA ratings of 3, 4X, 7, and 12, and NEC/CEC compliance with Class I, Division 2 hazardous-location rating. This combination ensures suitability for hazardous/classified locations while maintaining compatibility with standard industrial control components and control stations.
Yes. The NCD34 is designed for hazardous/classified locations and offers robust protection suitable for oil & gas, chemical processing, mining, and other high-risk environments. Its combination of NEMA ratings and NEC/CEC compliance supports reliable operation in outdoor and harsh indoor areas, helping you meet industry standards while protecting critical control equipment.
Prioritize correct suffix selection (MSR1 or MSR2), secure seals and gaskets, and ensure proper enclosure grounding and bonding per the wiring diagram. Verify conduit entry protection and maintain enclosure integrity during maintenance. Use compatible accessories recommended by Eaton to uphold NEMA ratings and Class I, Division 2 compliance during all phases of the lifecycle.
The NCD34 reduces downtime through rugged construction and certified protection, lowering maintenance frequency in hazardous environments. Its compact footprint and MSR suffix compatibility shorten wiring and commissioning, delivering faster project completion and lower total cost of ownership for control panels deployed in challenging facilities.
