Eaton 300TPHSR231 Switched Capacitor Bank - UL Listed, CSA Certified
Part Number: 300TPHSR231
Quick Summary
Eaton LV AutoVAR 600 capacitor bank is a low-voltage switched capacitor solution for power factor correction in industrial facilities. Many plants struggle with rising utility penalties when reactive power drifts, causing inconsistent voltage and reduced equipment efficiency. UL Listed and CSA Certified configurations help ensure safety, reliability, and regulatory compliance across electrical distribution and control panels. In addition to robust protection, a durable NEMA 1 floor-mounted enclosure supports indoor installations, while compatibility with AUTOVAR 600 enables scalable capacity for evolving loads. This approach delivers measurable business value through improved efficiency and predictable electrical performance.

FAQs
The 300TPHSR231 is designed for floor mounting in an indoor space with an NEMA 1 enclosure, 240V, 60 Hz operation, and fused protection. Plan for a robust foundation to support the 987 lb weight, ensure proper clearances around the 27 in depth, 41.3 in width, and 80 in height, and align with AUTOVAR 600 interfaces.
A 720A rating dictates feeder sizing, bus bar capacity, and protective device selection to accommodate peak currents without overheating. Design should include appropriately rated circuit breakers, conductors, and grounding, ensuring each phase can safely carry the expected load in a three-phase 240V system.
Yes. It is specifically designed for low-voltage three-phase applications, offering 240V operation, 300 kVAR of reactive support, and 12 x 25 kVAR steps to tailor correction. It integrates with AUTOVAR 600 for scalable, automated VAR control in industrial plants.
The unit is UL Listed and CSA Certified, signaling compliance with safety and performance standards for electrical equipment. These certifications support acceptance by inspectors and ensure safer installation in US and Canadian facilities, reducing project risk and streamlining procurement.
Expect improved energy efficiency and reduced utility penalties due to effective power factor correction. The system uses fused protection for safety and requires minimal maintenance beyond routine inspection. A typical Eaton warranty applies (one year from installation or 18 months from shipment), contributing to predictable lifecycle costs.
