Eaton 175MCSR431W AutoVAR Capacitor Bank - UL 508A
Part Number: 175MCSR431W
Quick Summary
Eaton LV AutoVAR 300 capacitor bank is a three-phase power factor correction device designed for industrial electrical systems. When reactive power is not managed, facilities incur higher utility charges and voltage swings that threaten motor efficiency. UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications help ensure safe, compliant installation. Wall-mounted, 480V, 175 kvar AutoVAR technology supports scalable energy savings and regulatory compliance across facilities. With dimensions of 14 in depth, 36 in height and width, and a 270 lb weight, it fits standard wall spaces in industrial environments while delivering robust three-phase capacity for motors, drives, and lighting loads.

FAQs
The 175MCSR431W is designed for 480V three-phase electrical systems and is a wall-mounted AutoVAR capacitor bank with a 3R enclosure. It fits standard industrial panel spaces and supports automatic reactive power compensation, making it suitable for facilities with heavy motor loads and HVAC drives. Ensure your distribution panel and enclosure can accommodate the 14 x 36 x 36 in footprint and 270 lb weight.
The unit provides 175 kvar of reactive power compensation at 480V. AutoVAR continuously monitors voltage and current to inject or withdraw capacitive reactance, improving the system power factor, reducing reactive charges, and stabilizing voltage during load changes. This translates to lower energy costs and better motor performance in industrial settings.
Yes. With its three-phase AutoVAR design, 175 kvar rating, and 480V operation, the 175MCSR431W is appropriate for manufacturing lines, process equipment, and data center power rails where tight voltage regulation and energy efficiency are critical. Its wall-mount enclosure and standard certifications simplify integration into existing electrical rooms and rack layouts.
The unit carries UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications. These attest to safe electrical design, wiring practices, and performance under industrial conditions. For facilities subject to North American electrical codes, these certifications facilitate inspections, approvals, and ongoing compliance with procurement standards.
Maintenance for a capacitor bank like the 175MCSR431W is typically minimal, focusing on periodic inspections and connection integrity. ROI comes from reduced reactive power charges and improved voltage stability, which reduce equipment wear and energy waste. The exact payback depends on site load profiles, existing power factor, and utility tariffs.
