FAQs
The DH264FRK is rated for 200 A and supports wire sizes from #6 AWG up to 250 kcmil Cu/Al. It uses a two-pole, fusible configuration without neutral, enabling straightforward integration with 480/600 V motor circuits. For retrofit projects, ensure conductor sizing aligns with the fuse class and enclosure clearances; the unit’s 30 in L, 18 in W, and 9.5 in H footprint fits standard electrical room layouts.
This switch is UL Listed and features a NEMA 3R enclosure, painted galvanized steel construction, and a 600 V rating. These specifications provide outdoor and indoor resilience against dust, rain, and moderate corrosion, delivering compliant protection for industrial facilities such as packaging, processing, and mining plants.
The DH264FRK offers a maximum of 50 hp per phase (1PH @ 480/600 V TD/600 Vdc). This makes it suitable for moderate to high-demand motors in pump, fan, and conveyor applications, allowing panel designers to optimally size fuses and conductors while achieving selective coordination and reduced downtime during faults.
Yes, the NEMA 3R enclosure is designed for outdoor or damp indoor environments. Maintenance considerations include periodic inspection of fuse elements, enclosure seals, and mounting hardware; the unit’s fusible without neutral design simplifies fault isolation, and the Class H fuse provides predictable replacement while maintaining continuity of service for downstream loads.
Two-pole, two-wire configuration with clear labeling, compatible wire range, and a compact 30 × 18 × 9.5 inch footprint streamline installation. UL Listed certification expedites compliance checks, and the 200 A / 50 hp capability aligns with common motor control center specs, enabling faster panel builds and more predictable lead times for OEMs and system integrators.
