Eaton 350TPHSR231M capacitor bank - UL Listed
Part Number: 350TPHSR231M
Quick Summary
Eaton 350TPHSR231M capacitor bank is a low-voltage, three-phase switched capacitor bank designed for power factor correction in industrial facilities. When utilities penalize poor PF or motor start-up creates voltage fluctuations, operators face higher costs and equipment stress. UL Listed and CSA Certified ensure safety and regulatory compliance, while the rugged NEMA 1 KK floor enclosure and optional integrated main breaker support reliable, long-term operation. This solution pairs with the AUTOVAR 600 family to deliver consistent performance, with clear business value through reduced energy spend and improved voltage stability.

FAQs
Plan for a floor-mounted installation in a suitable indoor area with adequate clearance for maintenance and wiring. Ensure the 240V three-phase supply at 60 Hz matches the unit, and accommodate the NEMA 1 KK enclosure. If choosing the integrated main breaker, verify panel space and disconnect coordination with existing protection schemes.
Key specs include 350 kVAR kVA rating, 844A amperage, 240V voltage rating, 60 Hz frequency, three-phase configuration, and seven 50 kVAR steps. The enclosure is NEMA 1 KK, designed for floor mounting, with fuse protection and an optional integrated main breaker for enhanced safety and control.
Yes. It is designed for low-voltage, three-phase power factor correction, operating at 240V and 60 Hz. It can be used with AUTOVAR 600 systems to provide scalable correction, improving power quality in manufacturing floors, motor-heavy plants, and other industrial facilities.
The unit is UL Listed and CSA Certified, providing recognized safety and compliance for North American installations. These certifications support procurement decisions and help meet regulatory audits and internal standards for electrical equipment.
Warranty terms follow Eaton Selling Policy 25-000: one year from installation or eighteen months from shipment, whichever comes first. This coverage protects against manufacturing defects and supports planned maintenance planning and asset lifecycle management.
