AutoVAR technology provides dynamic voltage regulation by switching capacitor banks to match load. This improves power factor, reduces reactive power charges, and stabilizes voltage profiles during motor starts and load swings. It is well-suited for 600V three-phase systems and data centers, manufacturing facilities, and large HVAC installations. The 175 kvar capacity, in a wall-mounted 14 in by 36 in by 60 in cabinet, enables precise compensation and minimizes transformer losses while conserving floor space. The compact enclosure simplifies retrofits and allows easy integration with Eaton's LV AutoVAR 300 family for staged capacitor switching and scalable performance. UL 508A, CSA, UL 810, IEEE 18 certifications deliver safety and reliability for electrical rooms and panels. Engineered for rugged environments, this capacitor bank supports long service life with predictable maintenance needs.

FAQs
This wall-mounted unit requires a suitable dedicated enclosure and access for wiring and switching. It supports 600V three-phase systems and is designed for retrofit into existing switchgear without major rearrangements. Ensure clearance for the 14 x 36 x 60 in cabinet, proper clearances around the top and sides, and compliance with UL 508A and CSA wiring practices.
Yes, the 600V rating aligns with common industrial power distribution practices. The three-phase design delivers up to 175 kvar of reactive power to improve PF, reduce transformer losses, and limit utility demand charges. Verify panel space, protector coordination, and busbar clearances per NEC and manufacturer guidelines.
UL 508A ensures safe appliance control panel compliance, CSA Std C22.2 No. 190 confirms electrical safety, UL 810 addresses enclosure and environmental requirements, and IEEE 18 covers capacitor bank performance under load. These certifications reduce commissioning risk, support code compliance, and simplify procurement for regulated facilities.
AutoVAR actively tunes reactive power by switching capacitors in response to voltage and load. This improves power factor, lowers reactive charges, and stabilizes voltage during startup transients. Over time, facilities can expect lower utility bills, reduced transformer stress, and better motor efficiency, especially for large fans, pumps, and conveyors.
Plan for periodic inspection of connections, enclosure seals, and capacitor bank state. The wall-mounted design simplifies retrofits; use compatible Eaton AutoVAR controllers and follow the specification sheet for wiring and switching sequences. Routine checks help extend life and ensure reliable operation during peak loads and transitions.
