Eaton LV AutoVAR filter 900THFSR632MWY - NEMA 3R
Part Number: 900THFSR632MWY
Quick Summary
The Eaton LV AutoVAR filter is a high-capacity harmonic filtering solution for large industrial drive systems. Operators struggle with voltage sags and distorted power caused by nonlinear loads, leading to motor overheating and unplanned downtime. It carries UL 508A, CSA C22.2 No. 190, UL 810, and IEEE Std. 18 certifications, underscoring safety, enclosure integrity, and electrical performance. This rugged, floor-mounted filter delivers scalable 900 kvar of reactive power at 60 Hz in 600 V three-phase networks, enabling precise power quality control close to the load. By stabilizing voltage and reducing harmonic currents, it supports regulatory compliance, extends equipment life, and lowers utility penalties, while aligning with existing Eaton infrastructure and project-driven timelines to improve project certainty and ROI.

FAQs
Yes. The 900THFSR632MWY is designed as a floor-mounted, three‑phase harmonic filter compatible with standard 600 V power systems and existing Eaton components. Its floor mounting and NEMA 3R enclosure support stable operation in plant rooms or outdoor locations, while the integrated main breaker simplifies integration with upstream switchgear and reduces wiring complexity for rapid commissioning and easier service.
Key specifications include a 600 V rating, 60 Hz operation, 4.2H tuning, and a total 900 kvar capacity built from nine 100 kvar steps. This configuration delivers scalable harmonic compensation right at the load, reduces total harmonic distortion, improves power factor, and supports larger motor drives while maintaining stable voltage and reduced thermal stress across critical equipment.
Certifications UL 508A, CSA C22.2 No. 190, UL 810, and IEEE Std 18 provide regulatory assurance for electrical safety, enclosure integrity, and performance in demanding industrial environments. These approvals simplify supplier qualification, support compliance audits, and help customers meet site standards for electrical installations without compromising uptime. They also align with ongoing industry safety programs and reduce retrofit risk.
From a financial perspective, the AutoVAR filter lowers total cost of ownership by reducing utility penalties, improving motor efficiency, and extending equipment life. The rugged enclosure and low-maintenance design minimize downtime and service interventions, while scalable kvar steps support future load growth without replacing the filter. This translates to predictable ROI across mid- to large-size facilities.
To maximize reliability in harsh environments, plan for proper clearances around the 3700 lb unit, ensure adequate ventilation, and route cables from the main breaker with proper strain relief. Position the 172.8 in × 80 in × 25 in footprint to maintain service access, and schedule periodic inspection of connections and cooling airflow to prevent overheating.
