Eaton Specification Sheet - DG321URB
Feature → Business Impact → Application: General duty non-fusible design enables simple disconnection and maintenance, reducing nuisance trips and enabling faster, safer servicing in routine control circuits for manufacturing lines and packaging operations. This translates to lower downtime and predictable maintenance budgets in general distribution panels. Feature → NEMA 3R rainproof enclosure with painted galvanized steel offers weather resistance and corrosion protection, delivering reliable operation in outdoor or damp locations, including loading docks and weather-exposed panels. This protects critical control wiring and improves uptime in facilities with variable environmental conditions. Feature → Three-pole, three-wire configuration rated at 30 A and 240 V supports standard motor control and line-side disconnects, delivering clear wiring paths and compatibility with common conduit runs in plant electrical rooms and switchgear cabinets. Product weight of 6 lb and compact dimensions (6.88 in depth, 10.81 in height, 6.38 in width) provide a space-saving footprint that simplifies retrofit projects and new panel builds. Feature → Non-fusible, single-throw operation offers straightforward operation and reduced inventory of replacement fuses, streamlining training and maintenance workflows for maintenance teams. Feature → UL Listed with NEC 230.62 barrier compliance ensures compliance and safe integration into compliant electrical assemblies, minimizing risk during audits and enabling faster approvals in project documentation. Feature → Neutral kit compatibility note clarifies service-entrance suitability, ensuring correct installation practice and preventing costly rework; this supports engineers designing service disconnects for main distribution with confidence. Insight: In real-world installations, these switches are favored for their ease of procurement, predictable performance, and compatibility with standard panel enclosures, contributing to measurable project savings and reduced commissioning time.

FAQs
The DG321URB requires a neutral kit when used as a service entrance, as noted in the catalog. Plan for proper kit installation to meet NEC requirements and ensure safe, code-compliant disconnects. Verify enclosure clearance, proper conduit routing, and that the barrier is maintained during installation to prevent access to live parts.
Yes. It features a NEMA 3R rainproof enclosure with painted galvanized steel, designed to withstand outdoor and damp environments. This construction helps protect internal components from weather elements, reducing maintenance cycles and extending service life in outdoor panels and exposed installations.
The DG321URB is a three-pole, three-wire, non-fusible, single-throw switch rated for 30 A at 240 V. Use standard 30 A conductors and follow proper wiring practices for three-phase control circuits. Ensure correct lugs and terminal torque per manufacturer guidelines to maintain electrical integrity.
The unit is UL Listed and designed to comply with NEC 230.62 barrier requirements. It is housed in a NEMA 3R enclosure, which supports safe operation in indoor and outdoor environments. Follow local codes and NEC provisions when integrating into panels or service equipment.
With a rugged galvanized steel enclosure and a non-fusible design, downtime is reduced due to simplified maintenance and quicker servicing. The unit’s 6 lb weight and compact dimensions ease installation, while the 1 year warranty (or 18 months from shipment) provides a clear maintenance window, contributing to lower lifecycle costs and predictable ROI for general-duty safety switching in manufacturing and distribution environments.
