FAQs
Install the Eaton 450TPHSR631MW by placing the floor-mounted NEMA 3R enclosure in a clean, accessible area and using the integrated main breaker option if chosen. Route three-phase connections to the AUTOVAR 600 interface, verify 600 V rating and 60 Hz supply, and install fused protection per local codes. Follow Eaton installation guidelines and rely on qualified technicians for safe commissioning. Ensure proper ventilation and clearance for heat dissipation.
Key specs include a 432 A amperage rating, 450 kVAR capacity, 600 V voltage rating, 60 Hz frequency, three-phase configuration, nine steps of 50 kVAR (9 x 50 kVAR), and protection via fuses with an optional integrated main breaker. The enclosure is floor-mounted and rated NEMA 3R, designed for low-voltage industrial environments and compatibility with AUTOVAR 600.
Yes. It delivers precise reactive power correction to reduce voltage drop and improve motor efficiency on heavy-load lines. With 450 kVAR and 432 A capacity, it supports motor drives, compressors, and CNC equipment common in manufacturing. The 9 x 50 kVAR steps allow fine-tuning for varying loads, while the floor-mount NEMA 3R enclosure accommodates busy plant floors.
The unit is UL Listed and CSA Certified, confirming safety and regulatory compliance. The NEMA 3R enclosure and floor-mount design meet industrial protection standards, facilitating installation in harsh environments and simplifying insurance and regulatory acceptance. These certifications help ensure safe operation, reliability, and easier procurement through recognized quality marks.
Energy savings come from improved power factor and reduced utility demand charges, with ROI highly site-specific based on load profile and tariff structures. Maintenance centers on regular checks of capacitor cells, protective fuses, and enclosure integrity; the design emphasizes reliability for long service life. The one-year warranty (or 18 months from shipment) provides protection during early operation and commissioning.
