The Eaton 125MCSR4313M AutoVAR capacitor bank is a three-phase, switched-capacitor system designed for 480V industrial networks. It provides 125 kvar of reactive power with a compact footprint suitable for wall-mounted installations. This configuration delivers rapid voltage stabilization and power-factor improvement, reducing kVA demand and lowering energy costs across fluctuating loads. Wall-mounted design and modular construction support quick commissioning and straightforward maintenance in busy facilities. It is engineered for reliability in demanding environments and integrates seamlessly with Eaton LV control schemes for remote monitoring and control. By automating reactive power compensation, operators gain uptime and process confidence while maintenance teams benefit from clear documentation and standardized parts. In regulated facilities, compliance through UL 508A, CSA, UL 810, and IEEE 18 is maintained with minimal effort. This solution also reduces procurement risk by using standardized, field-proven components and clear OEM guidance. And because the unit is designed for industrial environments, it tolerates mounting vibration and temperature variations while delivering consistent performance.

FAQs
Consider wall-mounted placement with adequate clearance for wiring, HVAC, and service access. Verify mounting hardware supports a 60 in x 60 in footprint and 300 lb weight, and ensure adherence to UL 508A and CSA requirements during installation. Plan conduit routes and control wiring to Eaton LV systems for seamless integration and future expandability.
Yes. This capacitor bank is designed specifically for 480V three-phase networks, delivering 125 kvar of reactive power to improve power factor and reduce kVA demand. It connects to standard LV distribution equipment and aligns with typical industrial control schemes; proper wiring and protective device coordination are essential for safe operation.
The unit carries UL 508A for industrial control panels, CSA Std. C22.2 No. 190, UL 810 for electrical enclosures, and IEEE Std. 18. These certifications support regulatory compliance, electrical safety, and reliable performance in harsh industrial environments.
AutoVAR automatically switches reactive power in response to system conditions, improving voltage stability and power factor. Benefits include lower kVA demand, reduced energy costs, extended equipment life, and less stress on transformers and feeders. This translates to predictable performance, easier maintenance, and faster commissioning in demanding facilities.
Maintenance is generally minimal due to a robust, industrial-grade design and standardized components. The ROI is driven by improved PF, reduced demand charges, and lower energy consumption over time. Regular inspections of connections, enclosure integrity, and control wiring, coupled with access to Eaton’s documentation, help sustain performance and simplify parts replacement if needed.
