FAQs
Installing the DH221NGK3 requires a standard indoor panel with a two-pole disconnect and a neutral conductor for 240V circuits. Mount it in a compatible enclosure (NEMA 1) with proper barrier spacing and NEC-compliant wiring methods. The unit’s footprint supports retrofit and minimizes panel rework, aiding rapid commissioning and safer maintenance.
Key specs include a 30A amperage rating, 240V voltage rating, two-pole configuration, and fusible with neutral. This combination delivers reliable overcurrent protection, enables selective fuse coordination in motor circuits, and supports safer startup and lockout procedures. UL Listed status further simplifies procurement and compliance auditing.
Yes, the DH221NGK3 is designed for indoor use in environments protected by a NEMA 1 enclosure. It is not rated for outdoor or hazardous locations. For dusty facilities, ensure proper enclosure sealing and maintain recommended ambient conditions. This setup helps maintain safety margins and reduces corrosion risk over time.
The DH221NGK3 is UL Listed and NEC 230.62 barrier compliant, with a NEMA 1 enclosure. These certifications confirm electrical safety, code-adherent barrier protection, and suitable indoor enclosure protection. They simplify procurement, reassure auditors, and support regulatory compliance across manufacturing plants and panel builds.
Expected ROI stems from reduced downtime due to reliable disconnection and quick fuse replacement. The unit’s robust build and 30A 240V rating improve motor protection and arc containment, lowering the likelihood of unscheduled outages. Over time, this translates to fewer maintenance calls, safer operation, and lower total cost of ownership for plant-wide electrical protection.
