Eaton 450TPCSR431 LV AutoVAR 600 capacitor bank - UL/CSA
Part Number: 450TPCSR431
Quick Summary
Eaton LV AutoVAR 600 capacitor bank provides switched-capacitor power correction for industrial electrical systems. Sizing and commissioning challenges often result in over- or under-correction, wasting energy and stressing motors and drives. This unit carries CSA Certification and UL Listings (UL 508A, UL 810) with IEEE Std. 18, supporting reliable operation and control-system compatibility. By offering digital metering and a floor-mounted, single-door enclosure, it enables real-time monitoring while simplifying installation. With a 540 A rating and 450 kVAR in a three-phase, 480 V package, it supports scalable PF correction; 9 x 50 kVAR steps, optional 65 kAIC MCCB, and IQ 250 metering enhance performance and ROI for retrofit or new-build projects.
