Eaton Specification Sheet - DH321FRB-CSA
With a 30A, 240V rating, the DG321FRB-CSA provides precise overcurrent protection for general-duty load centers. This specification minimizes nuisance trips and protects startup surges on conveyors, pumps, and fans, improving line uptime. Engineers can confidently specify this unit for control panels in manufacturing, material handling, and packaging lines. Three-pole, three-wire construction with fusible without neutral simplifies wiring and improves fault isolation in compact control panels. The device accommodates Class H fuses and clear labeling for safe replacement, reducing maintenance time and ensuring regulatory compliance. It is well-suited for three-phase motor drives and allied control circuits in medium-scale machinery. Durable NEMA 3R enclosure in painted galvanized steel provides weather resistance for outdoor or semi-exposed installations. The rugged enclosure lowers corrosion risk and maintenance costs while protecting sensitive components from dust, moisture, and impact. This makes the DG321FRB-CSA ideal for outdoor panels, remote machine enclosures, and harsh factory floors. CSA certification and NEC 230.62 barrier compliance support safety audits and procurement specs. The enclosure's corrosion resistance combined with CSA labeling helps meet regulatory requirements while simplifying supplier qualification. For engineers, this means fewer compliance questions and faster project approvals. Compatibility with standard panel layouts and a robust 539 lb form factor signals a trusted, heavy-duty solution for industrial environments. The cartridge fuse safety switch integrates smoothly with existing wiring schemes and spare fuse inventories, reducing installation time and stock carry costs. In practice, this translates to lower total cost of ownership and reliable service life across multiple shifts.
