Eaton 125MCSR4313W LV AutoVAR 300 capacitor bank - UL 508A

Centralized reactive power control from the AutoVAR 300 capacitor bank translates directly to a measurable business outcome: improved power factor, reduced demand charges, and steadier voltage across the line. In practical terms, that means lower utility costs and fewer interruptions during peak loads. It’s particularly effective in 480V three-phase manufacturing lines, process areas, and heavy equipment rooms where sag and harmonic distortion can impact productivity. UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications provide safety, reliability, and traceable quality. The result is easier compliance reporting, lower risk of regulatory penalties, and confidence during audits. In practice, engineers can specify this unit knowing it meets essential electrical-safety standards for control panels and industrial environments. Rugged 3R enclosure with wall-mount compatibility supports installation in tight spaces and existing switchgear bays. The design reduces mounting footprint and simplifies wiring, enabling faster retrofits and upgrades. Operators benefit from easier maintenance access and reduced downtime during capacitor bank replacements or balancing routines. The 125 kvar rating meets medium to large facility needs for reactive power support, delivering effective VAR control at 480V. The compact 14 in depth and 36x36 in footprint facilitate placement alongside switchgear or in mechanical rooms, while its three-phase configuration aligns with standard electrical distributions in industrial automation environments. Eaton provides detailed specification sheets and field-sizing guidance, accelerating procurement and project approvals. By aligning with engineering standards and available documentation, teams can optimize installation planning, validate ongoing energy savings, and realize a faster return on investment through improved power quality and reduced energy waste.
