Eaton Crouse-Hinds NCSC21 NCS Enclosure - Hazardous Locations
Part Number: NCSC21
Quick Summary
NCSC21 NCS enclosure provides rugged protection for control circuits in hazardous locations. In practice, engineers face wiring reliability and maintenance challenges in harsh environments where enclosure ratings must align with local codes. This solution offers NEC/CEC compliance with Class I, Division 2 hazardous location ratings and a NEMA 3 4X 7 12 enclosure defense, delivering durable performance in tough settings. Its non-metallic construction and compact through-feed design help streamline panel layouts, reduce lifecycle costs, and simplify installation across automation and control systems. This makes it an ideal fit for scalable control architectures in oil, gas, or chemical processing facilities, where safe, compliant operation matters as much as uptime.

Feature → Business Impact → Application: Through-feed design and 3/4 inch trade size simplify wiring and enable clean, feed-through layouts, reducing installation time and wiring fault points in compact control panels for hazardous locations. This translates to faster commissioning and lower maintenance costs in automated process lines. Feature → Business Impact → Application: Non-metallic construction provides corrosion resistance and dielectric protection, extending enclosure life in chemical and wash-down environments while maintaining electrical safety for control stations in harsh facilities such as refineries and chemical plants. Feature → Business Impact → Application: Certified for Class I, Division 2 and NEC/CEC compliance with NEMA 3 4X 7 12 ratings gives engineers confidence to deploy near process equipment, enabling safer operations and regulatory adherence in hazardous locations. Feature → Business Impact → Application: Small footprint dimensions (7.25 in tall, 4.38 in wide, 3.81 in deep) and light weight (2.31 lb) offer space-efficient installation in crowded switchgear rooms or control cabinets across oil and gas plants. Feature → Business Impact → Application: Documentation and spec sheets from Eaton, UL certifications, and catalog pages streamline procurement and project validation, reducing design risk and accelerating approvals for automation projects.
