Three-phase 240V AutoVAR capacitor bank with a 100 kvar rating improves power factor and reduces reactive power charges across industrial LV distribution networks; this translates to lower utility costs and better voltage regulation on manufacturing lines. Wall-mounted design and compatible footprint (14 in L x 60 in H x 36 in W) enable space-efficient retrofits in existing electrical rooms, with a weight of 330 lb that supports stable, secure installation. UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications provide regulatory confidence and safer operation, reducing commissioning risk. The AutoVAR control enables automatic reactive power optimization, minimizing manual adjustments and delivering consistent energy savings in continuous-production environments. Easy integration with standard LV panels supports quicker start-up and reduced downtime. This is a cost-effective approach to power factor correction for data centers, manufacturing floors, and large facilities, with predictable maintenance and long lifecycle reliability.
