FAQs
Yes. The 450TPHSR631 is designed as a 450 kVAR, 432 A, 600 V, three-phase capacitor bank used with Eaton AUTOVAR 600 systems. It features a floor-mount, NEMA 1 enclosure and heavy-duty capacitor cells for rugged indoor installation. UL Listed and CSA Certified options simplify procurement and ensure compliance for North American facilities.
Key specs include a 450 kVAR rating, 432 A amperage, 600 V voltage, and 60 Hz frequency in a three-phase configuration. It uses nine 50 kVAR steps (9 x 50 kVAR) to fine-tune power factor across load ranges, enabling scalable correction and smoother voltage profiles without oversizing the bank.
Ideal for indoor, floor-mounted applications in manufacturing, processing, and heavy industry where consistent PF correction is needed. The NEMA 1 enclosure and heavy-duty cells suit dusty or mildly harsh indoor environments, while the 450 kVAR capacity supports varying load profiles typical of motors and drives.
The 450TPHSR631 carries UL Listed and CSA Certified safety approvals, ensuring conformity with North American electrical safety standards. The enclosure is NEMA 1 for indoor protection, and the unit is designed for straightforward integration with Eaton’s AutoVAR ecosystem, simplifying audits and regulatory compliance.
Expect improved energy efficiency and reduced demand charges due to precise PF correction. The heavy-duty capacitor cells and fuse protection enhance reliability, lowering maintenance downtime. A one-year warranty (or 18 months from shipment) provides initial coverage, while ongoing energy savings and compatibility with AUTOVAR 600 contribute to a favorable total cost of ownership.
