Feature: 30A, 240V rating in a three-pole, four-wire configuration provides robust line-side protection for standard 3‑phase panels. Business impact: This specification minimizes overcurrent events while supporting safe isolation during maintenance, helping facilities avoid unplanned downtime and costly line stoppages. Application: Ideal for general-duty safety switching in motor control centers, machine panels, and OEM equipment across manufacturing floors. The combination of high-current capability and predictable trip characteristics supports scalable protection as line loads evolve. Feature: NEMA 1 enclosure with painted steel construction delivers durable indoor protection. Business impact: Enclosure integrity reduces corrosion and shields sensitive components from dust in warehouse and shop-floor environments, improving long-term reliability and reducing replacement costs. Application: Well-suited for indoor electrical rooms, panel assemblies, and compact control enclosures in automotive, food & beverage, and packaging lines. Feature: Fusible with neutral configuration using Class H fuses. Business impact: Class H fuses provide reliable slow-blow protection with clear fault isolation, enhancing safety while enabling straightforward maintenance. Application: Perfect for motors and equipment that require a neutral current path in 3‑pole, 4‑wire systems, with dual-element options for higher hp ratings. Feature: UL Listed and NEC 230.62 compliant barrier ensure safety and code-compliant installation. Business impact: Certification-backed protection helps meet regulatory requirements and reduces risk during inspections. Application: Install in facilities that mandate recognized safety devices and clear barrier protection around live parts. Feature: Compact footprint and balanced dimensions facilitate easy integration. Business impact: Lightweight design (6 lb) and modest footprint simplify retrofits and reduce shipping and installation time. Application: Suitable for panel retrofits in legacy equipment and new builds with space constraints. Industry context: As an Eaton product, DG321NGB is designed for reliable general-duty safety switching in industrial environments where motor protection and safe isolation are essential.

FAQs
DG321NGB provides a three-pole, four-wire configuration rated at 30A and 240V, designed for standard 3‑phase panels. Its NEMA 1 painted steel enclosure supports indoor installations, and the fusible-with-neutral design simplifies wiring while maintaining safe isolation during maintenance. This makes retrofits and new builds straightforward for machine controls and OEM equipment.
DG321NGB is UL Listed and features a NEC 230.62 compliant barrier, ensuring safety and regulatory alignment in industrial environments. The NEMA 1 enclosure further confirms suitability for indoor panel installations. These certifications help with passing inspections, improving installer confidence, and reducing risk in critical motor protection applications.
Catalog notes indicate that maximum horsepower ratings apply only when dual-element fuses are used. For typical general-duty protection, you’ll rely on the 30A, 240V rating with a Class H fuse configuration. For higher hp motors, plan a dual-element fuse strategy or alternative protection that matches the load to prevent nuisance trips.
DG321NGB measures 6.88 inches in depth, 10.69 inches in height, and 6.38 inches in width, with an approximate weight of 6 pounds. This compact footprint supports easier integration into crowded control panels and helps minimize added enclosure space during installation or retrofit projects.
The DG321NGB is ideal for motor protection and general-purpose safety switching in manufacturing and packaging lines, machine control panels, and OEM equipment. Its 30A, 240V rating, fusible-with-neutral configuration, and NEMA 1 enclosure make it a reliable choice for indoor, low-to-mid-size industrial applications requiring safe isolation and straightforward wiring.
