FAQs
The DH466FGKV is a four-pole, four-wire unit designed for indoor NEMA 1 installations. When retrofitting or panel-building, ensure cabinet clearance for the 58 in depth and 27.5 in width, and allow proper space for cartridge fuse access. Verify compatible bus connections and fuse cartridge availability to minimize downtime during commissioning.
Key ratings include a 600 A amperage, 600 V maximum voltage, and a four-pole four-wire configuration. It supports up to 400–500 hp at 480–600 V three-phase, making it suitable for large motors and heavy protection duties in industrial settings.
Yes. The DH466FGKV is rated for 600 V and is configured for heavy-duty, four-pole operation with cartridge fuses, aligning with industrial drive and protection schemes used in heavy machinery and processing lines.
The DH466FGKV carries UL Listed certification, which supports safety and compliance in industrial environments. In addition, its NEMA 1 enclosure and cartridge fuse configuration align with standard industry practices for indoor protection and maintenance efficiency.
The enhanced visible blade provides clear, immediate status indication without needing a viewing window. This reduces misoperations during testing or maintenance, shortens fault-diagnosis cycles, and supports safer lockout/tagout procedures across production lines.
