FAQs
Prepare the panel space for a three-pole, four-wire switch, verify 240 V supply and correct conductor sizing, and align the fusible-with-neutral configuration with the downstream circuit. Use proper lockout/tagout procedures, mount in the NEMA 3R enclosure, and route conductors to rated terminals to ensure safe isolation during maintenance.
The DH328NRK delivers 1200 A amperage rating at 240 V, in a three-pole, four-wire configuration. It uses Class L fuse provisions and a fusible-with-neutral setup, with UL Listing and a NEMA 3R enclosure. It is designed for rugged service in industrial environments and supports reliable fault isolation and safe operation.
Ideal for outdoor substations, machine halls, and process lines, particularly where high-current protection and durable enclosures are required. Its NEMA 3R, galvanized steel enclosure protects against weather and corrosion, while the three-pole, four-wire design accommodates common industrial power distribution arrangements.
The DH328NRK is UL Listed and features a NEMA 3R enclosure, with Class L fuse provisions and a neutral-capable fusible configuration. These certifications ensure compliance with safety and reliability standards, simplify procurement for regulated projects, and support safe maintenance practices and lockout/tagout procedures.
Using the DH328NRK can reduce downtime through reliable protection and safer isolation, lowering maintenance interruptions for high-current feeders. The UL listing, rugged enclosure, and long lifecycle contribute to predictable upkeep costs, while the one-year warranty (or 18 months from shipment) provides a clear initial risk management window.
