FAQs
This unit is floor-mounted in a large NEMA 1 enclosure with a floor footprint designed for industrial installations. Allow adequate clearance for front access to the integrated main breaker, fuse protection, and maintenance. The dimensions are 29 in (depth) by 41.3 in (width) by 80 in (height), with a total weight near 949 lb, so plan for a reinforced surface and proper lifting provisions. Electrical room airflow and proximity to other heavy equipment should be considered to ensure safe operation and serviceability.
The bank provides 250 kVAR of reactive power correction at 240V, 60 Hz, three-phase operation, with a 601A amperage rating. It features 10 steps of 25 kVAR each, enabling granular control over reactive compensation. This combination supports precise PF improvement and voltage stabilization across typical industrial loads such as motors, pumps, and drives, while maintaining safe current levels and reliable operation.
Yes, it is designed for use with AUTOVAR 600 systems, providing seamless interoperability within Eaton’s low-voltage VAR solutions. This compatibility simplifies procurement, reduces engineering assessment time, and ensures coordinated protection and control. Installation benefits include an integrated main breaker option, standardized wiring practices, and documented safety procedures that streamline commissioning and future expansions.
The 250TPHSR231M carries UL Listed and CSA Certified marks, signaling adherence to recognized safety and performance standards for electrical equipment. These certifications facilitate approvals in many regulatory environments, support warranty claims, and provide confidence to facilities teams and inspectors when validating critical power factor correction installations.
The product carries Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. ROI depends on site energy costs and load profiles, but typical gains come from reduced reactive charges, improved motor efficiency, and stabilized voltage that can lower maintenance and downtime costs. A properly tuned bank can deliver payback within months to a couple of years in many industrial settings.
