FAQs
The DH326FPKV is a three-pole, fusible-without-neutral switch rated for 600 A at 240 V. It supports 3-wire wiring and large conductor sizes, including up to 750 kcmil Cu/Al, with #2 to 600 kcmil copper/aluminum conductor ranges for appropriate terminations. This enables flexible integration into existing panels and new builds alike while maintaining code-compliant spacing and secure connections.
The 600 A rating provides robust overload protection for large motors, while the HP rating (up to 200 hp for 3-phase at standard TD) at 240 V guides safe selection for pump, compressor, and conveyor drives. This combination minimizes nuisance trips, improves startup reliability, and supports scalable motor protection across mixed-load applications.
Yes. The DH326FPKV is UL Listed and NEC 230.62 barrier compliant, with a NEMA 4 enclosure that supports indoor and outdoor use. The device is designed to meet regulatory standards for safe operation, maintenance, and servicing in industrial facilities, helping facilities remain compliant during inspections and audits.
This switch is ideal for heavy-duty power distribution and motor protection in manufacturing lines, process plants, and outdoor electrical rooms. Its NEMA 4 enclosure, Class H fuse provision, and high amperage rating make it suitable for harsh environments where reliability and safety are prioritized, such as steel, chemical, and pulp/paper facilities.
The robust steel enclosure and UL/NEC-compliant design reduce maintenance frequency and downtime, while straightforward fuse replacement minimizes service time. Over the equipment life, this translates to lower total cost of ownership, fewer unplanned outages, and faster, safer maintenance cycles in high-demand production environments.
