FAQs
The HCU2133D7N12 is a floor-mount, NEMA 12 enclosed unit designed for 690 V three-phase systems. It integrates with existing electrical rooms or panels by coordinating with common bus arrangements and feeder breakers. Ensure sufficient clearance for airflow, plan cable entries to match the enclosure knockouts, and verify compatibility with your drive and distribution equipment to avoid space and wiring clashes.
Expect substantial harmonic distortion mitigation thanks to active harmonic correction, with the unit rated at 133 A and 690 V. The design includes 8.2 kW watt losses internally, and the system operates on 50/60 Hz. When paired with appropriate drives and power conditioning, total system efficiency improves as harmonic currents are reduced and overall power factor stabilizes.
The unit complies with IEC 61000-3-2 and IEC 61000-3-4, IEEE Std. 519, UL 508C, and CSA C22.2 No. 14. These certifications help ensure electrical noise control, overload protection, and safety in industrial environments, supporting faster procurement approvals and reducing compliance risk for manufacturing, mining, and continuous-process facilities.
ROI is driven by reduced energy waste from harmonics, improved motor life, and fewer nuisance trips. Maintenance is minimized because the unit is factory-rated for continuous operation, with diagnostics accessible via standard control interfaces. Expect lower long-term operating costs as power quality stabilizes and drive systems experience fewer abnormal shutdowns.
Industries with heavy motor drives, conveyors, pumps, lifts, and robotics—such as automotive, food and beverage, packaging, and general manufacturing—benefit most. Any facility running mixed loads on 690 V three-phase networks can gain improved power quality, longer equipment life, and easier compliance with electrical standards.
