Feature → Business Impact → Application: The DH224NGK provides a heavy-duty fusible switch with a neutral line, rated for 200 A at 240 V, enabling robust motor protection and safe power isolation in demanding environments. This configuration reduces arc-flash risk and motor damage, delivering tangible uptime improvements for conveyors, pumps, and fans in manufacturing floors. The enhanced visible blade enables quick status checks, cutting maintenance time and minimizing mis-wiring during panel maintenance or upgrades. In practice, technicians can diagnose faults faster, improving mean time to repair (MTTR) and minimizing production interruptions. The NEMA 1 painted-steel enclosure, combined with Class H fuses, offers durable indoor protection and reliable performance in busy control rooms and machine cells. Compatibility with standard fuses and time-delay devices simplifies upgrade paths and lowers spare-part inventory strains. UL Listed and NEC 230.62(C) barrier compliance provide regulatory assurance, reducing compliance risk during audits and new installations. The compact footprint (30 in depth, 18 in width, 9.5 in height) with a 43 lb weight supports straightforward mounting in existing enclosures and control panels, enabling rapid integration in new line builds or retrofits.
