Eaton 400TPCSR431M AutoVAR capacitor bank - UL 508A
Part Number: 400TPCSR431M
Quick Summary
The Eaton LV AutoVAR 600 capacitor bank is a 480V three-phase reactive power solution designed to improve power quality in industrial facilities. Engineers often face rising energy costs and PF penalties when adding large motor loads or unbalanced systems. UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications provide safety, reliability, and compliance across panels. Designed for floor-mounted, three-phase installations, it coordinates with existing switchgear while enabling scalable reactive power correction. This solution integrates with Eaton's engineering support and datasheets to accelerate commissioning and minimize downtime. Its footprint of 26 in by 38.5 in and height of 78 in fits standard industrial enclosures while supporting precise capacitor replacement.

Phase
Three-phase
Three-phase switched capacitor bank delivers rapid reactive power compensation at 480V. This reduces utility demand charges and improves voltage stability, yielding measurable energy savings across continuous operations. In practice, automation lines and HVAC systems experience fewer PF penalties when this bank is integrated alongside existing protective devices. High kvar rating of up to 400 kvar enables substantial correction for medium to large motor clusters and process equipment, reducing grid reactive power draw and stabilizing voltage for sensitive equipment. The floor-mounted design and dimensions (26 in depth, 38.5 in width, 78 in height) allow straightforward integration with minimal enclosure modification, enabling faster implementation in retrofit projects. Certifications including UL 508A, CSA, UL 810, and IEEE 18 ensure regulatory compliance and safer operation across industrial controls and panels, supporting risk management and audit readiness. Documentation and design guides from Eaton, including the Specification Sheet, accelerate commissioning while maintaining safety margins, reducing downtime and lifecycle costs. Built for rugged plant environments, the unit’s weight and build quality support reliable, long-term serviceability with straightforward maintenance access.

FAQs
The 400TPCSR431M is a floor-mounted, three-phase capacitor bank designed for 480V systems and standard industrial enclosures. It integrates with common switchgear layouts and protective devices, simplifying wiring, protection coordination, and commissioning. When pairing with existing equipment, verify clearance, grounding, and available transformer/feeder capacity to ensure seamless, code-compliant installation and predictable performance.
Key specs include 480V operation, three-phase configuration, 400 kvar reactive power rating, and a footprint of 26 inches by 38.5 inches with a height of 78 inches. Weight is approximately 902 pounds. The product name is Eaton LV AutoVAR 600 capacitor bank, catalog number 400TPCSR431M, with UPC 786685147246. Certifications include UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18.
UL 508A confirms panel and electrical enclosure safety for industrial control equipment, CSA Std. C22.2 No. 190 addresses electrical safety in Canada and the US, UL 810 covers electrical wiring for appliances and equipment, and IEEE Std. 18 provides specific guidance for capacitor banks. Together, they assure ongoing compliance, safer operation, and audit-ready documentation for facility inspections and procurement.
By delivering substantial reactive power compensation in a 480V three-phase system, the AutoVAR bank improves power factor and voltage stability. This reduces utility demand charges, minimizes PF penalties, and lowers energy losses associated with reactive power, translating to lower operating costs, especially in facilities with large motor and HVAC loads.
A comprehensive Eaton Specification Sheet is available for the 400TPCSR431M, along with installation guides, wiring diagrams, and safety instructions.
