Feature: Active Harmonic Correction capability continuously monitors and neutralizes harmonic currents, reducing total harmonic distortion on three-phase loads. Business Impact: lowers current stress on transformers and breakers, improves power factor, and reduces losses in drives and motors. Application: ideal for automated production lines, CNCs, and variable-frequency drives where nonlinear loads are prevalent. Feature: High-current capability at 94A and 600 V with 50/60 Hz compatibility. Business Impact: enables stable operation of heavy automation and motor drives, reducing voltage drop and nuisance trips. Application: retrofit into existing switchgear in factories and warehouses. Feature: NEMA 12 floor-mounted enclosure with integral disconnect. Business Impact: enhances safety, simplifies maintenance, and reduces wiring complexity during service events. Application: harsh industrial environments requiring splash/dust resistance. Feature: Top or bottom cable entry and substantial footprint for flexible installation. Business Impact: minimizes retrofit planning and allows easier integration with existing bus bars and panels. Application: line-side connections in machine rooms and utility panels. Feature: Broad certification coverage (IEC 61000-3-2/3-4, IEEE 519, UL 508C, CSA) for regulatory alignment. Business Impact: reduces audit risk and accelerates project sign-off across process and manufacturing sectors. Application: plants with strict power quality and safety requirements. Feature: Comprehensive warranty (Eaton 25-000 policy; one year from installation or 18 months from shipment). Business Impact: predictable service lifecycle and lower long-term maintenance costs. Application: asset management programs across multiple facilities.

FAQs
Planning should account for floor-mount installation in a dedicated switchgear area, ensuring adequate clearance for the 56.18 in width, 87.24 in height, and 26.65 in depth. Use the NEMA 12 enclosure with integral disconnect, and decide on top or bottom cable entry to match existing wiring routes. Heavier equipment (over 1,315 lb) requires appropriate raising and bolting procedures and alignment with service clearances.
The unit actively cancels harmonic currents, lowering total harmonic distortion (THD) and improving power factor. This reduces current peaks, decreases transformer and switchgear stress, and lowers energy losses in drives and motors. The result is smoother operation of nonlinear loads, fewer trips, and improved overall line reliability on 50/60 Hz systems at 600 V.
Yes. Its three-phase, 600 V rating and IEEE 519/IEC compliance make it appropriate for data centers, manufacturing automation, and motor-drive applications. The integrated disconnect and NEMA 12 enclosure support safe installation in data halls or production floors, while the 94 A capacity aligns with mid-to-large automation loads without excessive footprint.
The unit is certified to IEC 61000-3-2, IEC 61000-3-4, IEEE 519, UL 508C, and CSA C22.2 No. 14. These certifications help satisfy regulatory requirements for electromagnetic compatibility, electrical safety, and third-party acceptance, simplifying customer audits and facilitating smoother project sign-offs in regulated industries.
Eaton offers a 25-000 warranty policy: one year from installation or 18 months from shipment. While ROI is project-specific, improvements from reduced harmonic losses, extended equipment life, and fewer power-quality-related trips typically translate to lower maintenance costs and improved uptime over the asset’s life.
