Five 50 kvar modules deliver 250 kvar total, enabling scalable PF correction that matches evolving load profiles and reducing utility penalties while improving voltage stability and system efficiency. This configuration translates to measurable energy savings, lower line losses, and improved motor performance across mixed-duty cycles in manufacturing, HVAC, and process industries. The solution is built for three-phase 60 Hz operation at 600 V, ensuring seamless compatibility with standard industrial power distribution and minimizing retrofitting risk during upgrades or expansions. Heavy-duty capacitor cells are engineered for reliability in harsh environments, extending service life and reducing maintenance intervals while maintaining PF performance under fluctuating loads. Integrated fuses provide essential overcurrent protection, protecting capacitor elements and downstream equipment and lowering the risk of unplanned downtime. Certifications such as CSA, UL 508A, and IEEE Std. 18 reduce procurement risk and streamline compliance for utilities, OEMs, and installation teams. Dimensions and weight are planned for straightforward rack or panel integration, helping space-constrained facilities plan layouts with confidence.

FAQs
The 250TPHSR631 is designed for three-phase 600 V systems and fits standard LV switchgear. Plan for adequate clearance around the unit, ensure compatible enclosure height for the 80 inch tall arrangement, and wire in the 241 A rating with proper fuses. Verify gland sizes, wiring torque specs, and alignment with local codes (CSA UL 508A). Pre‑install checks reduce commissioning time and ensure safe, reliable operation from day one.
This capacitor bank provides 250 kvar total correction (5 x 50 kvar modules), enabling scalable PF correction for varied load profiles. By raising the power factor closer to unity, line losses drop, motor efficiency improves, and utility penalties decline. The result is lower energy bills, reduced voltage drops on long feeders, and improved equipment performance across pumps, fans, and compressors.
Yes. The unit carries CSA Certified and UL Listed markings, is UL 508A compliant, and aligns with CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18. These certifications provide safety assurances, facilitate utility and contractor approvals, and support dependable procurement for regulated facilities and critical infrastructure.
Industries with heavy motor loads and multiple inductive devices benefit most, including manufacturing, HVAC systems, pumps and compressors, conveyors, and large facility power systems. The three-phase, 600 V rating and 60 Hz operation fit common plant electrical architectures, while the 5 x 50 kvar modules support staged upgrades as demand grows, protecting capital investments and supporting energy-efficiency programs.
Regular inspection of fuses and capacitor cells is recommended to maintain peak PF correction. The unit uses heavy-duty capacitor cells designed for durability in industrial environments, reducing maintenance frequency. The documented warranty covers one year from installation or 18 months from shipment, whichever occurs first, and routine checks help prevent unexpected downtime while preserving PF performance over the product life cycle.
