Eaton DH361NDKJ-DEMA Heavy duty fusible safety switch-UL98

Three-pole, four-wire construction with fusible neutral enables safe, coordinated switching for three-phase circuits, improving fault containment and reducing arc-flash exposure in control panels. This configuration translates to lower maintenance costs and faster service restoration in manufacturing lines that demand reliable power isolation. In practice, engineers install this switch on machine feeds and panelboard trunks to protect critical loads while maintaining neutral integrity for control and sensing circuits. The Class J fuse clips enhance fuse reliability and simplify routine replacements, delivering consistent performance and reducing downtime during maintenance windows. For facilities with harsh environments, the NEMA 12/3R enclosure offers solid enclosure protection against dust, dirt, and moisture, aligning with industry standards while lowering corrosion-related wear. The load side voltage monitor provides real-time visibility into circuit status, enabling proactive diagnostics and faster fault resolution. This combination supports safer commissioning, easier tripping verification, and improved overall equipment efficiency. With a 600 VAC / 250 VDC rating and 30 A nominal current, the device supports a wide range of industrial power distributions, minimizing the need for adapters or rewiring when expanding line capacity. Field modification to meet NEMA 3R rainproof requirements is possible by opening a factory drain hole, offering installation flexibility for outdoor or damp locations without specialized enclosures. The product’s galvanized steel construction and 25 x 15 x 20 inch footprint balance rugged protection with reasonable integration space in control rooms and machine bays, reducing enclosure clutter and improving panel layout efficiency.
