FAQs
The unit is a three-phase, 480 V fixed capacitor bank rated at 75 kVAR with a 90 A capability, housed in a NEMA 12 enclosure. Plan for indoor installation with adequate clearance for maintenance, proper mounting on a stable surface, and secure connections to a compatible LV distribution panel. Use the 14 gauge steel, powder-coated enclosure to resist dust and moisture in typical plant environments.
The 75 kVAR capacity provides substantial reactive power support at 480 V, improving power factor and reducing reactive currents in the system. This can lower utility demand charges and transformer losses. The 90 A rating supports peak conditions, while the catalog note helps plan for 208 V operation by applying the 0.75 factor to 240 V kVAR values when needed.
Yes, the 7543HURF is an UNIPAK with Heavy-Duty Cells designed for low-voltage fixed capacitor systems and is compatible with Eaton Unipak families. Its C1 frame and NEMA 12 enclosure support straightforward integration into existing LV switchgear and motor drive configurations, though mounting and electrical interface should be verified against your specific enclosure layout and bus configurations.
The unit carries CSA Certification and UL Listing, ensuring compliance with widely recognized safety standards. Its NEMA 12 enclosure provides protection against dust and moisture in indoor industrial environments, complemented by the rugged 14 gauge steel powder-coated exterior for long-term durability in challenging plant conditions.
Warranty is Eaton Selling Policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. ROI depends on site-specific energy usage, PF improvements, and avoided penalties; the unit’s fixed 75 kVAR rating and efficient, durable construction support predictable energy savings and lower maintenance costs in the long term.
