Feature → Business Impact → Application: Three-phase 480 V, 60 Hz operation enables seamless integration with common industrial power distribution, delivering reliable power factor correction for motors, drives, and HVAC loads—reducing reactive power and improving voltage stability across the facility. Application: manufacturing lines, process plants, and large facilities seeking predictable energy costs. Feature → Business Impact → Application: 300 kVAR total rating achieved through 6 × 50 kvar steps allows staged correction aligned with load profiles, minimizing over- or under-correction and enabling smoother step changes during peak demand. Application: facilities with variable motor starts and varying loads where PF correction must scale with demand. Feature → Business Impact → Application: NEMA 3R enclosure provides outdoor and damp-location suitability, reducing stroage constraints and enabling rooftop or yard installations without costly enclosures. Application: outdoor mechanical rooms, exposed sites, or partially sheltered spaces requiring robust protection. Feature → Business Impact → Application: heavy-duty capacitor cells and fused protection enhance reliability and maintenance intervals, lowering spare-part inventories and unplanned downtime. Application: critical processes where uptime is non-negotiable. Feature → Business Impact → Application: UL Listed, CSA Certified, UL 508A/UL 810/IEEE 18 compliance assures supplier qualification and regulatory alignment, simplifying audits and procurement. Application: compliance-driven projects and regulated industries. Feature → Business Impact → Application: compact, modular design supports phased deployment and easier retrofit, offering installation efficiency and reduced commissioning time. Application: plant modernization and PF correction upgrades with minimal site disruption.

FAQs
Retrofitting this unit requires a suitable footprint and access clearances for a 41.3 in wide by 80 in tall enclosure with a 25 in depth footprint. It is designed for 480 V three-phase, 60 Hz power feeds and uses fused protection inside a NEMA 3R enclosure, enabling outdoor or semi-exposed installations. Ensure electrical bus compatibility, adequate ventilation, and adherence to local codes; pre-wiring and standardized mounting simplify site integration and commissioning.
The 6 × 50 kvar stepping provides a total 300 kvar PF correction capacity that can be staged to match load growth and startup surges. This granularity prevents over-correction and reduces penalties from utilities during peak demand. In practice, facilities see steadier voltage profiles and more predictable energy costs as motor primaries and HVAC loads start and ramp.
Yes, the unit is specified for 480 V three-phase systems and uses standard protective features such as fuses and heavy-duty capacitor cells. Its IEC/UL-aligned certifications support cross-vendor procurement, but verify bus ratings, wiring connectors, and enclosure fit before integration. The product’s dimensions and weight should be factored into space planning and crane/rigging considerations during installation.
The 300TPHSR431W carries UL Listed and CSA Certified marks, and complies with UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18. These certifications support electrical safety, control panel compatibility, and broader industrial application, helping with audits, insurance, and supplier qualification in regulated facilities.
With a 300 kvar total PF correction capability, facilities typically reduce reactive power and energy costs, yielding measurable ROI through lower utility penalties and reduced kVAR charges. Maintenance is streamlined by fused protection and heavy-duty cells; downtime is minimized due to robust NEMA 3R enclosure, and routine checks focus on fuse integrity and thermal performance, not frequent component replacement.
