Eaton HCU2235D6N2 Harmonic Correction Unit - IEEE 519
Part Number: HCU2235D6N2
Quick Summary
The Eaton HCU2235D6N2 Active Harmonic Correction Unit optimizes power quality for large three-phase industrial loads. When harmonics push current distortions, equipment can overheat, trip, or waste energy; this unit mitigates those risks. It carries IEEE Std. 519 and IEC 61000-3-2/3-4 certifications (plus UL 508C), enabling compliant operation across global facilities. Designed for floor mounting in a 600 V system, its NEMA 2 enclosure supports durable, maintenance-friendly installation, reducing downtime and warranty headaches while delivering long-term reliability and predictable performance for motor systems and other high-demand loads.

FAQs
The HCU2235D6N2 is designed for floor mounting in a 600 V, three-phase system and features a NEMA 2 enclosure with top or bottom cable entry and an integral disconnect. For retrofits, plan wiring paths to accommodate top or bottom entry, ensure proper clearances around the enclosure, and schedule isolation during maintenance due to the integral disconnect. Always follow local electrical codes and Eaton’s installation guidelines to optimize safety and performance.
This unit is compliant with IEEE Std. 519, IEC 61000-3-2, IEC 61000-3-4, UL 508C, and CSA Std. C22.2 No. 14. These certifications help ensure harmonic mitigation performance in regulated environments, enable cross-border deployment, and reduce regulatory risk for industrial facilities without additional external filters.
Yes. The HCU2235D6N2 supports a 50/60 Hz frequency rating, making it adaptable for facilities that operate on either standard in order to manage harmonics in diverse production lines without reconfiguring drive systems.
Eaton provides a warranty policy consistent with their standard terms: one year from installation or eighteen months from shipment, whichever occurs first. For service continuity, maintainers should follow Eaton’s recommended maintenance schedule and document any field issues promptly to ensure warranty coverage remains valid.
By reducing harmonic distortion, the HCU2235D6N2 lowers heating and losses in motors and transformers, decreases nuisance trips, and can extend equipment life. The result is improved system efficiency, reduced unplanned downtime, and a faster payback in facilities with large motor and drive loads that are sensitive to power quality and regulatory compliance.
