Eaton 150MCSR431MW AutoVAR capacitor bank - UL 508A
Part Number: 150MCSR431MW
Quick Summary
Eaton LV AutoVAR 300 capacitor bank improves power factor for 480V industrial systems. Facilities often battle rising energy costs and penalties driven by poor power factor. UL 508A and UL 810 certification, paired with CSA C22.2 No. 190 and IEEE 18, support safe, reliable operation in demanding environments. Wall-mounted and three-phase by design, it integrates with existing panels while minimizing floor space. With 150 kvar of reactive power at 480V, it supports code compliance and reduces demand charges, improving overall equipment efficiency and lifecycle costs. This enables engineers to meet performance targets without sacrificing safety or maintainability.

FAQs
The 150MCSR431MW is designed for wall-mounted, three-phase installation in 480V systems. Verify available wall space, ensure adequate clearance for service access, and mount on a sturdy surface suitable for a 310 lb unit. Connect to the panel through appropriately rated conductors, following the included Eaton specification sheet and UL 508A wiring guidelines. Plan for proper enclosure protection (3R) and secure mechanical fasteners before energizing the switched capacitor bank.
Key specs include a 150 kvar rating, 480V three-phase operation, wall-mounted 3R enclosure, dimensions of 14 in (D) x 60 in (H) x 36 in (W), and a weight of 310 lb. Certifications include UL 508A, UL 810, CSA C22.2 No. 190, and IEEE 18, making it suitable for industrial control panels and demanding environments.
Yes. With 150 kvar of reactive power at 480V, this AutoVAR bank provides effective power factor correction, helping to reduce utility demand charges and stabilize voltages across motors and conveyors typical in manufacturing facilities.
The unit carries UL 508A, UL 810, CSA Std. C22.2 No. 190, and IEEE Std. 18 certifications, and it uses a 3R enclosure design for enhanced safety and reliability in industrial installations.
Maintenance is generally minimal for switched capacitor banks, focusing on periodic inspection of connections and enclosure integrity. ROI is driven by reduced demand charges and improved power factor; actual payback depends on facility load profiles, duty cycles, and energy tariffs.
