Eaton 400TPHSR231 Switched Capacitor Bank - UL Listed
Part Number: 400TPHSR231
Quick Summary
Eaton 400TPHSR231 Switched Capacitor Bank improves power factor correction for low-voltage three-phase systems. Industrial facilities struggle with penalties, motor wear, and voltage fluctuations when capacitor banks are under- or over-sized or poorly protected. UL Listed and CSA Certified ensure field safety and regulatory compliance, while the floor-mounted NEMA 1 enclosure supports robust installation in demanding plants. This solution leverages AUTOVAR 600 compatibility and heavy-duty capacitor cells to deliver reliable, scalable reactive power support. By optimizing power factor, it reduces energy costs, extends motor life, and stabilizes voltage in processes with large inductive loads, delivering measurable business value for electrical procurement and operations teams.

Selling Policy 25-000 - Distribution and Control Products and Services
High-capacity reactive power: The Eaton 400TPHSR231 delivers 965 A and 400 kVAR with eight 50 kVAR steps, all protected by fuses. This arrangement enables precise, rapid switching to match fluctuating load, reducing voltage dips, line losses, and utility penalties. By sizing for worst-case inductive demand, it helps stabilize feeders feeding large motor drives and compressors in manufacturing lines. Heavy-duty capacitor cells: Heavy-duty capacitor cells are engineered for industrial duty cycles, resisting thermal stress and frequent switching without performance degradation. This reliability translates into longer service life, fewer outage events, and lower maintenance costs for continuous-process operations. In practice, asset uptime improves, supporting just-in-time production and better overall OEE metrics. Rugged enclosure and mounting: The NEMA 1 KK floor-mounted enclosure provides mechanical protection and ease of installation in cramped plant spaces. Clear labeling, fused protection, and accessible wiring reduce commissioning time and improve fault isolation during maintenance. The design also simplifies future expansion or retrofits with AUTOVAR 600 modules, enabling staged capacity upgrades. Electrical compatibility: With a 240V rating, 60 Hz, and three-phase configuration, the bank aligns with common low-voltage distribution in factories and process plants. It integrates with standard switchgear, MCCs, and harmonics mitigation systems, and supports selective capacitor switching to minimize outages. The modular step-size approach helps tailor reactive power compensation to load ramps while maintaining voltage within tolerance. Certifications and support: UL Listed and CSA Certified provide safety credentials reassure compliance during design reviews and in-district inspections. Eaton’s warranty policy provides coverage for installation and shipment timelines, reducing risk for procurement teams. Together with robust spare-parts availability and service support, the solution offers a proven ROI through energy cost savings and equipment protection.

FAQs
Yes. The 400TPHSR231 is designed for use with Eaton's AUTOVAR 600 system and is floor-mounted in a KK-sized NEMA 1 enclosure. It employs heavy-duty capacitor cells and fused protection to support staged expansions. This configuration minimizes retrofit risks and simplifies wiring, enabling quick commissioning in busy plants.
Key specs include 965 A amperage, 400 kVAR rating, 240 V, 60 Hz, and eight 50 kVAR steps. This combination allows precise, rapid reactive power compensation, improving voltage stability for motors and drives, reducing penalties from low power factor, and lowering energy losses in large-inductive-load environments.
Industries with heavy motor loads, pumps, and compressors—such as manufacturing, process plants, and packaging facilities—benefit most. The unit’s low-voltage, three-phase design and modular step sizing enable tailored correction for fluctuating loads, improving reliability, energy efficiency, and equipment longevity in continuous-operation environments.
The 400TPHSR231 is UL Listed and CSA Certified, reflecting rigorous safety and performance testing. These certifications support compliance during design reviews and inspections, while the NEMA 1 floor-mount enclosure provides rugged protection in demanding plant environments and simplifies regulatory adherence.
Warranty terms follow Eaton policy: one year from installation or eighteen months from shipment, whichever comes first. This reduces risk for procurement and maintenance teams. Coupled with spare-parts availability and service support, the solution delivers a clear ROI via energy savings, reduced downtime, and extended motor life.
