Eaton NCD32 Enclosure - Hazardous Locations Class I Div 2
Part Number: NCD32
Quick Summary
NCD32 enclosures protect electrical components in hazardous locations by housing two circuits in a rugged, compliant enclosure. Engineers often wrestle with meeting NEC/CEC and hazardous-location requirements while keeping maintenance costs down. This model carries NEC hazardous rating Class I, Division 2 and trusted NEMA protections, including 3, 4X, 7, and 12, to withstand demanding environments. Designed for 1 inch trade size control wiring and compatibility with MSR1 or MSR2 suffix options, it streamlines procurement, installation, and long-term service. Using this enclosure can reduce downtime and compliance risk in chemical plants, refineries, and other regulated facilities.

Eaton Specification Sheet - NCD32
Feature: Hazardous-location protection with NEC Class I Division 2 rating and NEMA 3 4X 7 12 ratings. Business impact: robust protection reduces risk of contamination, injury, or equipment damage in regulated environments, driving safer operations and lower insurance exposure. Application: suitable for chemical plants, refineries, and other facilities where equipment lives in classified locations and must endure dust, moisture, and corrosive exposure. Feature: Two circuits in a compact 1-inch trade size dead-end enclosure. Business impact: minimizes panel footprint and simplifies wiring, speeding up assembly and commissioning. Application: instrument racks and remote I/O junctions where space is at a premium and reliable termination is critical. Feature: MSR1 or MSR2 suffix compatibility. Business impact: seamless integration with Eaton MSR control stations; reduces change orders and downtime. Application: retrofit projects or scalable control architectures in hazardous zones. Feature: Durable materials and NEMA ratings for outdoor and corrosive environments. Business impact: long service life, lower maintenance costs, and lower total cost of ownership. Application: outdoor enclosures, chemical plants, offshore and rugged industrial settings. Feature: Comprehensive documentation and catalog support. Business impact: faster procurement, easier QA, and smoother compliance audits. Application: engineering offices, contractor teams, and QA departments managing regulated installations. This design emphasizes installation efficiency, lifecycle reliability, and regulatory alignment to support safer, more productive hazardous-location control panels.

FAQs
NCD32 is designed to pair with MSR1 or MSR2 suffix modules for hazardous-location control stations. Installers should mount the enclosure for vertical clearance, route conductors through the 1 inch trade size knockouts, and terminate per NEC guidelines. The MSR suffix ensures correct interlock and coordination with compatible control components, reducing commissioning time and potential wiring mistakes.
NCD32 carries NEC Class I, Division 2 hazardous-location rating and is listed with NEMA ratings of 3, 4X, 7, and 12. This combination supports compliance across NEC/CEC regimes, permits safe operation in hazardous areas, and helps meet documentation requirements for audits and safety approvals in oil, gas, and chemical processing facilities.
Yes. With NEMA 3 4X 7 12 ratings, NCD32 is engineered for rugged outdoor and harsh industrial environments. The enclosure provides dust, water, and chemical resistance, contributing to longer service life and reduced maintenance in exposed locations common in refineries, petrochemical plants, and outdoor installations.
NCD32 has a depth of 3.81 inches, height of 7.25 inches, width of 4.38 inches, and weighs 2.92 pounds. Its compact size supports space-constrained installations, while the two-circuit capacity and 1 inch trade size facilitate straightforward wiring and panel layout in control applications.
Official specifications include the Eaton NCD32 datasheet and catalog pages. Datasheets outline the two-circuit configuration, 1 inch trade size, MSR1/MSR2 compatibility, and the NEC/NEMA ratings.
