FAQs
When deploying the DH363FRK-CSA in service entrances, verify the Neutral Kit compatibility for service-entry use and ensure NEC 230.62 barrier compliance. Plan for three-pole, three-wire wiring with Class H fuses and a 600 V maximum rating. Allow adequate space for the 22.5 inch depth and 12.75 inch width, and confirm mounting on a suitable surface or panel; ensure proper grounding and enclosure fit for outdoor or indoor installation.
The 100 A rating with three poles supports reliable overload protection for motors and feeders up to 75 hp at 480/600 V. This allows designers to reduce starter and protection component counts while maintaining safe startup and shutdown sequences. In practice, you’ll size upstream fusing and conductors to the 100 A rating, align with NEC requirements, and optimize protection coordination across the drive system.
Yes. The DH363FRK-CSA uses a NEMA 3R enclosure, constructed from painted galvanized steel, which offers weather resistance for outdoor and semi-exposed indoor locations. This design helps resist rain, dust, and corrosion exposure while maintaining protective isolation for safe operation. For extreme environments, confirm additional accessories and installation clearances per Eaton guidelines.
This switch is UL Listed and CSA Certified, with NEC 230.62 barrier compliance. These certifications matter because they validate electrical safety, reliability, and code conformity, reducing procurement risk and simplifying regulatory audits. The combination supports safer installation in service entrances, panels, and motor feeders across industrial facilities while aligning with common safety purchasing criteria.
Maintenance needs are minimal but important: periodic inspection of fuse integrity, enclosure seals, and terminal connections helps sustain performance. ROI comes from reduced downtime due to robust protection, lower miswiring risk, and simplified service entrance configurations. The 21 lb, compact 22.5x12.75x9 in footprint also lowers installation time and reduces space-related costs in control panels.
