FAQs
Yes. The 660TPCSR431M AutoVAR capacitor bank is designed for 480V three-phase environments and integrates with standard Eaton LV layouts. It arrives as a floor-mounted enclosure with clearly labeled connection points. Ensure a qualified electrical technician handles installation, follow the UL 508A guidelines, and verify panel clearance and ventilation for safe operation.
Key specs include a 660 kvar reactive power rating with a 120 kvar bank configuration, three-phase 480V operation, and 26 in by 38.5 in by 78 in footprint. Expect substantial power factor improvement, reduced reactive charges, and stabilized voltage during motor starts and load ramps. The assembly is UL 508A, UL 810, and CSA certified for reliability.
This unit excels in facilities with mixed motor loads, fans, pumps, and conveyor systems where frequent startups drive reactive demand. It suits manufacturing plants, data centers, and process facilities needing consistent PF correction, voltage regulation, and reduced utility penalties, while fitting floor-mounted spaces without extensive enclosure remodeling.
The 660TPCSR431M carries UL 508A for industrial control panels, CSA Std. C22.2 No. 190 for Canadian compliance, UL 810 for electrical equipment, and IEEE Std. 18 for capacitors and capacitor banks. These certifications support safe operation, installation in compliant facilities, and smoother audits across North American sites.
The AutoVAR bank is designed for long life with minimal routine maintenance, reducing downtime and maintenance costs. Expect ROI from lower energy bills due to PF improvement, reduced demand charges, and extended motor life from stabilized voltages. Plan periodic inspections of enclosure integrity and capacitor bank connections to sustain performance.
