FAQs
The 350TPHSR431W is designed for outdoor or indoor use with a NEMA 3R enclosure, making outdoor mounting feasible in rugged environments. It operates on a 480 V three-phase supply at 60 Hz and requires a stable supply with appropriate overcurrent protection (fuses). Consider space for its 80 in height, 41.3 in width, and 25 in depth, plus a 900 lb weight for forklift-friendly handling and secure mounting.
Key specs include 480 V three-phase operation, 60 Hz frequency, 421 A amperage rating, and a total 350 kVAR with 7 × 50 kVAR steps. This provides scalable power factor correction, enabling precise reactive power management and energy cost reductions in dynamic load environments.
Yes, it is well-suited for manufacturing, HVAC-heavy facilities, data centers, and pumping systems where reactive power costs are a concern. Its 350 kVAR capacity with 7 × 50 kVAR steps allows staged correction, improving motor efficiency, reducing penalties, and supporting voltage stability across varying production loads.
The unit carries UL Listed, CSA Certified, UL 508A, and IEEE Std. 18 alignment, ensuring electrical safety, panel compatibility, and control-system interoperability. These certifications simplify compliance during audits and help meet industry regulations for electrical equipment installed in commercial and industrial facilities.
Maintenance is streamlined by robust heavy-duty capacitor cells and protective fusing, with a one-year warranty from installation or 18 months from shipment. ROI comes from reduced reactive power charges, improved motor efficiency, and lower voltage fluctuations, yielding energy savings and enhanced equipment reliability over the system’s service life.
