Eaton 900THFSR632Y AutoVAR Filter - UL 508A Certified
Part Number: 900THFSR632Y
Quick Summary
The Eaton LV AutoVAR filter stabilizes voltage and balances load in large three-phase 600 V networks. Facilities often struggle with voltage sags, harmonics, and equipment wear that reduce uptime and increase maintenance costs. It carries UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications to support safe, compliant installations. Designed for 600 V systems and 60 Hz operation, it delivers measurable business value through improved power quality and reduced risk. In practice, this enables tighter control of kVAR stepping and easier scalability across growing plants. End users typically see lower energy costs, reduced component stress, and longer equipment life.

Feature → High-capacity AutoVAR with 900 kvar and 4.2H tuning enables rapid response to load changes, delivering a significant business impact by reducing voltage sags and improving power factor in 600 V three-phase networks. This supports safer, more reliable operation in large manufacturing environments and chemical plants where power quality directly affects yield and downtime. Application: 600 V three-phase systems requiring scalable reactive power correction, including auto-tuneable kvar stepping. Feature → 60 Hz operation and three-phase design ensure compatibility with standard industrial power networks, improving reliability and simplifying integration. Business impact: fewer voltage fluctuations and smoother equipment performance, reducing surprises in critical processes. Application: automotive, metal forming, and process industries that rely on stable power delivery. Feature → Floor mounting with NEMA 1 enclosure delivers safe, durable installation in busy factory floors. Business impact: easier compliance with facility safety standards and robust protection against dust and incidental contact. Application: indoor plants with crowded utility rooms and short access paths. Feature → Large enclosure footprint (172.8 in L × 80 in H × 25 in W) and 3700 lb weight provide rugged, service-friendly hardware with ample access for maintenance and upgrades. Business impact: long-term reliability, lower lifecycle risk, and predictable install planning. Application: retrofit projects in legacy facilities or new builds requiring heavy-duty power correction equipment. Feature → Certifications include UL 508A, UL 810, CSA Std. C22.2 No. 190, and IEEE Std. 18, reducing regulatory risk and simplifying system integration. Business impact: smoother audits and faster panel approvals. Application: regulated sectors like industrial controls and processing plants. Feature → 9 x 100 kvar stepping allows phased capacity upgrades as load grows, enabling scalable modernization without replacing the entire system. Business impact: capital expenditure is distributed over time, preserving CAPEX flexibility. Application: facilities expanding production volumes or adding new lines, where incremental kvar support is needed.

FAQs
Install the floor-mounted unit on a solid concrete pad with clear service access. Route 600 V three-phase power and control wiring per the Eaton catalog sheet, ensuring proper torque, protective grounding, and required clearances. Verify that the 900 kvar capacity and 9 x 100 kvar stepping modules are wired as specified, then commission with proper safety checks and calibration.
Key specs include a total reactive power capacity of 900 kvar with 4.2 H tuning, 60 Hz operation, 600 V voltage rating, three-phase configuration, and a NEMA 1 enclosure. It supports 9 x 100 kvar stepping for scalable upgrades and is designed for floor mounting in industrial environments to improve power quality and reduce sags.
The 900THFSR632Y is a reactive power correction device focused on voltage stabilization and power factor improvement. While it enhances overall power quality, for significant harmonic mitigation you should pair it with dedicated harmonic filters or a harmonics management strategy. It excels at reducing sags and balancing kvar in 600 V three-phase networks.
The unit carries UL 508A for motor control and panel safety, UL 810 for enclosure protection, CSA Std. C22.2 No. 190, and IEEE Std. 18, aligning with widely adopted industry standards. This simplifies regulatory approvals, reduces audit risk, and ensures safer integration into industrial control panels and facilities.
ROI depends on energy savings from improved power factor and reduced losses, plus extended equipment life due to lower circulating currents. Maintenance focuses on periodic electrical and mechanical checks, cleanings, and scheduled commissioning to preserve performance. Its scalable 9 x 100 kvar stepping enables phased investments aligned with plant growth.
