FAQs
The 900TPHSR431W is designed for floor mounting in a KK-sized NEMA 3R enclosure. Ensure adequate clearance for maintenance access, proper ventilation, and weather protection for outdoor or semi-outdoor installations. Verify service clearances around the conduits and fuses, and plan wiring routes to minimize impedance and stress on feeders. Use compatible AUTOVAR 600 configurations and ensure correct synchronization with existing power electronics.
The unit provides 900 kVAR total capacity, configured as nine steps of 100 kVAR each (9 × 100 kVAR). This stepped approach allows precise reactive power targeting across varying load conditions, supporting scalable power factor correction for diverse industrial loads while keeping feeder currents within design limits.
Yes. The capacitor bank is housed in a NEMA 3R, KK-sized floor-mount enclosure designed for rugged environments, offering protection against dust, moisture, and weather exposure. For outdoor deployments, ensure appropriate mounting surface and ventilation, and consider additional enclosure sealing if exposed to harsh conditions or direct water spray in accordance with site requirements.
The 900TPHSR431W carries UL Listed and CSA Certified marks, signaling compliance with key safety and electrical standards in North America. These certifications help facilities meet procurement specifications, insurance requirements, and regulatory obligations, reducing risk during commissioning and operation while facilitating smoother audits and maintenance planning.
Eaton provides a one-year warranty from the date of installation (or eighteen months from shipment, whichever occurs first). Regular maintenance focuses on fuse protection integrity, capacitor cell condition, and wiring connections. Planned maintenance reduces unexpected downtime, improves reliability, and supports favorable total cost of ownership by extending service intervals and minimizing unplanned outages.
