Eaton Specification Sheet - EDSCM21
Copper-free aluminum construction reduces weight and improves corrosion resistance, lowering shipping and installation costs. This translates to easier handling on site and reduced fatigue for technicians during installation, enabling faster deployment in demanding plants. Through-feed hub design with two 3/4 inch hubs and two 1 inch hubs simplifies wiring topology, reduces terminal crowding, and cuts field wiring time, supporting quicker panel upgrades and easier future expansion. The single-gang footprint with overall dimensions of 7.56 inches in length, 3.31 inches in height, and 3.5 inches in width enables compact panel layouts, delivering space savings and flexible mounting in restricted cabinets. Certifications and ratings provide regulatory confidence: NEC/CEC compliance, hazardous-location approvals for Class I, II, and III, plus NEMA 3, 7, 9, reducing compliance risk and project rework. Compatibility with DSD device cover sub-assemblies simplifies maintenance planning and spare-parts strategy, while robust copper-free aluminum construction improves longevity in dusty or humid conditions. Overall, EDSCM21 supports modular, scalable control architectures with lower total cost of ownership, fewer field-service events, and faster time-to-operation in hazardous environments.

FAQs
The EDSCM21 is designed to work with DSD device cover sub-assemblies, enabling modular customization of control stations in hazardous areas. This compatibility simplifies stock management, accelerates field replacements, and supports scalable panel designs without sacrificing enclosure integrity or compliance. Engineers can map wiring strategies around standard DSD configurations to minimize lead times and reduce the risk of mis-matched components in Class I, II, and III environments.
Key considerations include using copper-free aluminum construction for corrosion resistance in harsh environments, selecting the through-feed hub arrangement (two 3/4 in and two 1 in hubs) to match wiring topology, and ensuring mounting in a single-gang enclosure to fit space-constrained panels. The unit’s dimensions (7.56 in L, 3.31 in H, 3.5 in W) support compact layouts, while NEC/CEC certification and NEMA ratings provide regulatory assurance for safe operation in hazardous locations.
Yes. EDSCM21 carries NEC/CEC standards compliance and hazardous location ratings that cover Class I Division 1 and 2, Class II Division 1 and 2, and Class III, along with a NEMA 3, 7, 9 rating. This combination ensures regulatory alignment, reduced compliance risk, and fewer design changes during approval processes for control panels operating in hazardous or classified locations.
The device body measures 7.56 inches in length, 3.31 inches in height, and 3.5 inches in width, with a weight of approximately 2.95 pounds. This compact, lightweight profile simplifies handling, reduces crane or technician effort during installation, and enables easier retrofits in existing panels while maintaining robust protection in challenging environments.
By employing copper-free aluminum for durability and corrosion resistance, along with modular hub options and compatibility with DSD cover sub-assemblies, the EDSCM21 reduces field-maintenance needs and spare-parts variety. Its compliant design minimizes rework during audits, accelerates future expansions, and supports faster, safer servicing, ultimately lowering total cost of ownership and boosting plant uptime in hazardous locations.
