FAQs
The HCU2120D5N1 is designed for three-phase 380-480V operation with a bottom cable entry and a wall-mountable NEMA 1 enclosure. Its 120A rating supports mid-range loads, enabling seamless retrofit or new-install projects without oversized cabinet footprints. Integration typically involves standard electrical connections, verified by its IEC and IEEE certifications for compliance and safety.
Expect notable reductions in total harmonic distortion and related heating in transformers and motors due to real-time harmonic cancellation. The device aligns with IEEE 519 and IEC 61000-3-2/3-4 standards, delivering improved power quality, reduced equipment stress, and better motor efficiency across typical industrial loads.
Yes. The unit carries UL 508C and CSA C22.2 No. 14 certifications, in addition to IEC and IEEE standards. This multi-scheme compliance supports safer integrations in regulated facilities and accelerates procurement approvals by addressing common regulatory requirements.
Eaton offers a warranty of one year from the date of installation or eighteen months from shipment, whichever occurs first. Routine maintenance is typically limited to periodic inspection of connections and enclosure integrity, with standard repair or replacement services available under the warranty terms to minimize downtime.
While initial investment covers the 120A harmonic correction unit, benefits include lower energy penalties, reduced cooling loads from better waveform control, and improved equipment reliability from decreased harmonic wear. Over time this translates to faster ROI through energy savings, improved uptime, and simplified compliance across multiple sites.
