FAQs
400TPHSR631 is designed for 600 V, 60 Hz three-phase power. It integrates with standard Eaton AutoVAR controllers and existing switchgear, reducing commissioning time. Its dimensional footprint (25 in depth, 41.3 in width, 80 in height) and 950 lb weight should be planned into the equipment room layout, ensuring proper ventilation and service access. Pre-installation checks should confirm available clearance and bus connections meet Eaton guidelines.
8 x 50 kvar indicates eight correction steps of 50 kvar each, totaling 400 kvar of reactive power correction. This allows tailored PF correction that matches load profiles, minimizes overshoot, and reduces utility penalties. Operators can sequence steps to respond to seasonal or process-driven demand changes, optimizing energy savings while maintaining voltage stability.
Yes. The unit carries UL Listed and CSA Certified markings, complemented by UL 508A, CSA Std. C22.2 No. 190, and UL 810 certifications. IEEE Std. 18 alignment further supports safe, reliable capacitor bank operation. This certification package eases regulatory compliance, enables safer cabinet integration, and supports maintenance and procurement audits in industrial facilities.
The bank measures 25 inches in depth, 41.3 inches in width, and 80 inches in height, with an approximate weight of 950 pounds. Plan for a dedicated, level mounting surface with adequate clearance for access, fuse servicing, and cooling. Ensure proper enclosure or room ventilation and allow space for future expansion. Electrical connections should follow OEM wiring diagrams and 600 V, three-phase feeder requirements.
ROI depends on facility load, energy tariffs, and PF targets; typical gains come from reduced reactive power charges and improved voltage regulation. Maintenance focuses on fuse protection and capacitor cell health, with Eaton’s design offering modular upgrades and simplified fault isolation. Regular inspections aligned with the warranty terms help maximize uptime, while the 25–18 month warranty coverage provides initial risk mitigation during early operation.
