FAQs
Yes. The 350TPHSR631W is designed for 600 V, three-phase, low-voltage installations and can integrate with existing AUTOVAR 600 setups. Its floor-mount, NEMA 3R enclosure supports retrofit applications in mechanical rooms or exterior spaces, with fuse protection for safety and a straightforward commissioning process to minimize downtime.
The 7 x 50 kVAR stepping provides granular VAR control, enabling precise accuracy in correcting power factor across varying loads. This staged approach improves efficiency, reduces demand charges, and allows phased commissioning, which is especially valuable during capacity expansions or seasonal load changes in manufacturing and data-center environments.
Industries with heavy, intermittent, or cycling loads—such as manufacturing, process facilities, data centers, and commercial facilities—benefit most. The unit’s high kVAR rating, modular steps, and robust enclosure suit applications requiring reliable low-voltage power-factor correction, scalable energy management, and compliance-ready installation.
This unit is UL Listed and CSA Certified, reflecting safety and reliability. It features a NEMA 3R enclosure suitable for both indoor and outdoor use, along with fused protection for safe operation. These certifications and protections help meet regulatory requirements and industry standards in regulated facilities.
Maintenance centers on scheduled inspections of capacitor cells and fuse integrity, with the heavy-duty design supporting extended service life in high-cycle environments. ROI is driven by reduced reactive power costs, improved voltage stability, and scalable VAR control, helping facilities achieve faster payback through lower utility charges and fewer capital upgrades.
