Feature → Business Impact → Application: The DH266FGK-LS is rated for 600 A with a 50 HP maximum at 250 Vdc, enabling protection for high-load motors and drives in conveyors, pumps, and presses while minimizing voltage drop and interruption time. This translates to improved uptime and predictable performance in automated lines. Feature → Business Impact → Application: A NEMA 1 painted steel enclosure provides indoor protection against dust and debris, reducing field maintenance and shielding critical components in control panels. This is ideal for factory floors and enclosed industrial cabinets where reliability and ease of service are paramount. Feature → Business Impact → Application: Fusible without neutral and Class H fuse configuration simplify wiring topology and protection coordination, lowering installation labor and potential wiring errors in two-wire, two-pole circuits across process lines. Feature → Business Impact → Application: The switch accommodates large conductors (1) #2 to (1) 600 kcmil and (1) #1/0 to (1) 750 kcmil Cu/Al, enabling direct feeder connections and reducing splices, which shortens commissioning time in heavy-duty installations. Feature → Business Impact → Application: UL Listed status and NEC 230.62 barrier compliance underpin regulatory alignment and safety documentation, while a 600 V rating supports a wide range of industrial feeders; combined with dimensions (64 in L × 26 in W × 13 in H) and a 130 lb weight, these specs inform footprint planning and installation logistics for new or retrofit projects.

FAQs
The DH266FGK-LS is designed for indoor, two-pole, two-wire configurations with a NEMA 1 enclosure. It supports large conductors up to 600 kcmil copper/aluminum and 750 kcmil equivalent, with overall dimensions of 64 in L × 26 in W × 13 in H and a weight of 130 lb. Plan floor or cabinet mounting accordingly and account for service clearances per NEC guidelines.
Yes, it accommodates large conductors: (1) #2–(1) 600 kcmil and (1) #1/0–(1) 750 kcmil Cu/Al. This reduces the need for splices and intermediate lugs, streamlining installation, decreasing labor time, and potentially lowering overall wiring costs for high-current feeders in industrial plants.
The DH266FGK-LS is UL Listed and NEC 230.62 compliant, with a NEMA 1 indoor enclosure designed for rugged industrial environments. It is rated for 600 V and 600 A, with Class H fuse provision and fusible without neutral, ensuring alignment with common safety and performance standards in electrical protection.
Industries relying on high-current motor protection, such as manufacturing conveyors, pumping stations, and automated assembly lines, benefit from the DH266FGK-LS. Its 600 A rating and robust enclosure are well-suited for protecting large drives and equipment in indoor control panels and process automation environments.
The robust painted steel NEMA 1 enclosure minimizes corrosion and debris ingress in indoor spaces, reducing maintenance needs. High-current compatibility and reduced wiring complexity lower installation and downtime costs, while UL Listing and NEC compliance help protect against regulatory delays, delivering long-term reliability and predictable ROI for capital projects.
