FAQs
The DH225NGKV is a two-pole, fusible-with-neutral switch designed for 3-wire configurations. For installation, verify panel width and depth compatibility (27 in x 57 in x 11 in footprint), connect Cu or Al conductors per Class H fuse provision, and mount within a NEMA 4 enclosure. Use proper tightening torque on lugs and ensure the NEC 230.62 barrier is maintained. This promotes safe maintenance access and reduces arc-flash risk during servicing.
The device delivers a 400 A amperage rating with a 240 V rating and a fusible with neutral configuration, enabling precise protective coordination for high-current motors and feeders. Its NEMA 4 enclosure protects against dust and moisture, while UL Listed certification confirms compliance with rigorous safety standards. This combination supports reliable operation in process lines, machinery drives, and critical infrastructure panels.
Yes. The DH225NGKV is UL Listed and features a NEC 230.62 compliant barrier, ensuring safe separation of live parts and protective installation practices. This certification supports auditor-ready safety documentation, reduces retrofit costs, and aligns with many industry codes for control panels, ensuring compliant deployments in manufacturing, water treatment, and facility automation environments.
Maintenance focuses on fuse replacement and enclosure integrity. The Class H fuse provision simplifies change-outs, while the NEMA 4 enclosure maintains performance in dusty or damp locations. Regular visual inspections, lugs torque checks, and verification of neutral integrity help prevent unplanned outages. The 57 in depth and robust steel construction support long service life with minimal corrosion risk.
ROI comes from reduced downtime, faster maintenance, and longer motor life due to reliable fault isolation and selective coordination. The UL Listing, NEC barrier compliance, and NEMA 4 protection minimize regulatory and field rework. Although initial capital is higher than non-fused options, the switch’s durability, replaceable fuses, and straightforward installation lower lifecycle costs and improve plant uptime.
