Feature → Business Impact → Application: The 660 kVAR AUTOVAR 600 delivers 792 A continuous current, enabling scalable reactive power support to maintain a healthy power factor as load swings. This translates into lower utility penalties, reduced voltage drop on long feeders, and fewer motor starts or slowdowns due to poor voltage. In manufacturing lines and HVAC-heavy facilities, the improved power quality directly supports higher equipment efficiency and longer asset life, particularly where variable-speed drives are common. Feature → Business Impact → Application: Floor-mounted, single-door enclosure with an L-frame provides a compact footprint that fits crowded electrical rooms and simplifies retrofit projects. With dimensions of 78 in height, 38.5 in width, and 26.25 in depth and a 1010 lb weight, site handling remains predictable and safe. The 11 x 60 kVAR stepped configuration lets you tailor reactive power to evolving load profiles, offering phased correction rather than a single, oversized bank. Feature → Business Impact → Application: Optional molded-case circuit breaker rated 65 kAIC at 480/600 V plus IQ 250 digital metering deliver enhanced protection and real-time energy visibility. This supports fast fault isolation, better upstream coordination, and data-driven optimization of energy use across fleets of motors and drives. Feature → Business Impact → Application: Certifications such as CSA, UL 508A, UL 810, and IEEE Std. 18 provide risk-managed procurement and compliant operation in regulated environments. The rugged, floor-mounted enclosure helps ensure reliable installation in industrial rooms, with easier maintenance routines and predictable lifecycle costs. Feature → Business Impact → Application: The combination of 660 kVAR capacity and modular step X kVAR planning supports energy management programs in facilities pursuing ongoing efficiency gains and demand-response readiness, delivering measurable ROI through reduced energy purchases and improved power quality metrics.

FAQs
For a floor-mounted enclosure like 660TPCSR431, ensure a suitable footprint in the electrical room with at least 78 inches of vertical clearance and 38.5 inches of width space, plus 26.25 inches of depth. The unit weighs approximately 1010 lb, so plan for proper lifting equipment and fork-access. Utilize the L-frame design for stable anchoring and accommodate optional IQ 250 metering wiring in accessible panels. Plan routing to minimize humane labor and reduce nuisance tripping while preserving maintenance access around the single-door enclosure.
The 660TPCSR431 delivers 660 kVAR of reactive power with a 792 A amperage rating, specifically configured for three-phase 480 V operation. By supplying rated reactive power during load swings, it mitigates voltage drop, reduces current in feeders, and lowers utility penalties tied to poor power factor. This makes it suitable for heavy motor loads, chilled- water systems, and drives that commonly cause lagging power factors.
The 660TPCSR431 is CSA Certified and UL Listed, with UL 508A and UL 810 compliance, plus CSA Std. C22.2 No. 190 and IEEE Std. 18 alignment. These certifications reassure safe installation and reliable performance in industrial environments, simplify procurement in regulated facilities, and help meet plant-wide safety and quality programs during audits and inspections.
The unit offers an optional IQ 250 digital metering package, enabling real-time energy usage monitoring, voltage and current data, and event logging. This supports energy management initiatives, enables tighter KPI tracking for power factor improvement, and provides actionable insights for ongoing optimization of feeders and motors in mixed-load facilities.
Warranty terms follow Eaton’s policy 25-000, offering one year from the date of installation or eighteen months from shipment, whichever occurs first. This coverage addresses manufacturing defects and provides a defined window for commissioning support. For service, engage Eaton-authorized technicians to ensure correct wiring, verification of IQ 250 connectivity, and proper coordination with upstream protection devices.
