Eaton 150MCSR631MW AutoVAR 300 capacitor bank - UL 508A
Part Number: 150MCSR631MW
Quick Summary
The Eaton LV AutoVAR 300 capacitor bank improves power factor for three-phase industrial systems. Unpredictable load swings can trigger penalties and voltage sags, so fast reactive power correction is essential. Certified to UL 508A, UL 810, CSA, and IEEE 18, this unit integrates safely into control panels and supports compliant installations. By delivering reliable capacitance in a compact wall-mount enclosure, it reduces wiring complexity and lowers total cost of ownership when deployed with Eaton or compatible third-party systems for data centers, manufacturing lines, or motor-driven applications. Its 600V rating and 150 kvar capacity enable scalable PF correction for mid-size facilities.
