The 900THFSR632MY LV AutoVAR filter delivers 900 kvar of reactive power compensation with a 4.2 H tuning, enabling dynamic correction of power factor and reduction of harmonic currents. Business impact: improved transformer loading, reduced energy losses, and extended electrical equipment life, translating to lower operating costs. Application: large manufacturing floors and heavy load banks where precise VAR control is required to stabilize voltage and protect sensitive drives. The 9 x 100 kVAR steps provide granular adjustment, allowing operators to match real-time load conditions and maintain peak efficiency. This results in predictable performance during peak shifts and startup transients, particularly in process industries and material handling. Compatibility and installation benefits include floor-mounted convenience, a robust NEMA 1 enclosure, and compatibility with standard main-breaker configurations, simplifying integration with existing electrical infrastructure. Common objections about installation footprint and maintenance are addressed by a 3700 lb footprint, 80.4 in length, 80 in height, and 25 in width, designed for accessible service and reliable long-term operation. Certifications and standards—UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18—provide regulatory confidence for panel builders and OEMs, supporting risk mitigation and faster procurement cycles. Overall, the Eaton AutoVAR filter delivers measurable efficiency gains, improved power quality, and a compelling ROI for facilities facing fluctuating loads and stringent compliance requirements.

FAQs
Plan for a floor-mounted installation with the NEMA 1 enclosure and KK size. Ensure adequate clearance for service access, verify foundation support for the 3700 lb unit, and connect to the main breaker using appropriate gauge wiring. Follow Eaton installation guidelines for proper tuning, step adjustments (9 x 100 kVAR), and safety disconnections. Schedule post-install commissioning to confirm harmonic suppression and voltage stabilization.
Key specs include a 600 V voltage rating, 60 Hz frequency rating, and a 900 kvar total reactive power with 4.2H tuning. It is floor-mounted with a three-phase configuration, enclosure type NEMA 1, enclosure size KK, and dimensions of 80.4 inches by 80 inches by 25 inches. The unit weighs about 3700 pounds and supports 9 steps at 100 kvar each.
Yes. The Eaton 900THFSR632MY is certified to UL 508A and CSA Std. C22.2 No. 190 for industrial control panels, UL 810 for enclosures, and IEEE Std. 18 for motor control systems. This certification suite helps ensure safe operation, regulatory compliance, and smoother acceptance by panel builders, OEMs, and end users in industrial environments.
AutoVAR filtering active-reactive power compensation reduces harmonic currents, lowers wasted energy, and stabilizes voltage under varying loads. This translates to less motor wear, fewer nuisance trips, improved drive efficiency, and better compliance with electrical standards. The result is higher overall equipment reliability and a clearer path to ROI through energy and maintenance savings.
Schedule periodic inspections of electrical connections, enclosure seals, and cooling pathways to prevent dust buildup and overheating. Verify tuning settings after major load changes or commissioning events, and inspect the main breaker interface for secure connections. Routine maintenance minimizes downtime and preserves the unit’s 60 Hz performance, 600 V reliability, and 900 kvar ratings over the lifecycle.
