FAQs
The HCU2120D5N2 is a floor-mounted unit with top or bottom cable entry and an integral disconnect, designed for straightforward installation in 380-480V three-phase systems. Plan for proper ventilation to accommodate the 2.8 kW watt losses, and place the enclosure in a protected, accessible location for maintenance and future servicing.
This unit aligns with IEEE Std. 519 and IEC 61000-3-2/3-4 harmonic limits, and carries UL 508C and CSA C22.2 No. 14 certifications. These standards support reliable performance in regulated environments and facilitate cross-border procurement and installation without additional risk.
Yes. The 120A, 380-480V, three-phase design targets systems with substantial harmonic activity from drives and motors. Its active harmonic correction reduces distortion, improves power quality, and helps maintain equipment uptime in data centers and manufacturing lines where clean power is critical.
Key specs include 120A amperage rating, 380-480V voltage range, 50/60 Hz compatibility, and three-phase operation. The unit is floor-mounted with a NEMA 2 enclosure and provides 2.8 kW watt losses. Footprint is substantial to accommodate cooling and service clearance; ensure adequate floor space in the installation area.
Eaton provides a standard warranty under policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. For maintainability, ensure routine inspections, confirm cabling integrity, and schedule preventive maintenance to preserve performance and extend asset life.
