FAQs
The DG323NRB is designed as a three-pole, four-wire safety switch with fusible neutral, suited for standard industrial panels and motor control centers. Mounting should follow the enclosure’s NEMA 3R rating for outdoor use, with proper wiring to the 240V supply and Class H fuses. Ensure clear access for maintenance and field wiring per NEC guidelines to support safe operation and compliance.
The DG323NRB provides a 100A amperage rating, 240V voltage rating, and uses Class H fuses with a fusible neutral configuration. It is a three-pole, four-wire device housed in a NEMA 3R enclosure and is UL Listed. The product supports dual-element fuse configurations for hp ratings as noted in the catalog, enabling scalable protection for motor and load circuits.
Yes. The DG323NRB uses a NEMA 3R enclosure made of painted galvanized steel, designed for outdoor and harsh environments. This construction provides weather resistance, corrosion protection, and reliable operation in exposed electrical installations, aligning with industrial outdoor protection requirements.
The DG323NRB is UL Listed and complies with NEC barrier requirements under NEC 230.62. These certifications support safe operation, easier approval during audits, and assurance that the unit meets recognized safety standards for general duty safety switches used in 240V, three‑phase systems.
By integrating a general duty safety switch with fusible neutral and UL-listed protection, the DG323NRB reduces wiring complexity and downtime during fuse replacements. Its durable NEMA 3R enclosure and compatibility with dual-element fuses help extend service intervals, simplify regulatory compliance, and lower total cost of ownership in industrial power distribution and motor protection applications.
