Eaton 75483MVF3 LV Unipak capacitor bank - NEMA enclosure
Part Number: 75483MVF3
Quick Summary
The Eaton LV Unipak capacitor bank is a fixed three-phase power factor correction unit designed for reliable operation in 4,800-volt industrial distributions. Operators struggle with weatherproofing, wiring complexity, and downtime during maintenance, especially when retrofitting older facilities. This model uses rugged NEMA 1, 3R, and 12 enclosures to deliver weatherproofing and dust protection, while the 14-gauge steel shell resists industrial wear. With viewing windows and serviceable access, it supports faster maintenance cycles, helping facilities reduce downtime while meeting PF correction and reliability goals. Additionally, it aligns with industry best practices for fixed capacitor banks, supporting efficient energy management and cost reduction across HVAC and motor loads.

Feature: UNIVAR XV fixed capacitor bank provides precise reactive power support for stable voltage profiles across essential equipment. Business Impact: Improves power factor, reduces wasted energy, and lowers demand charges, delivering measurable operating cost savings. Application: Suitable for transformer-feeder panels and dedicated motor drives in manufacturing lines seeking to optimize efficiency. Practical insight: Installations benefit from the unit’s viewing window and gasketed seal, which simplify routine inspections and maintain reliability in harsh environments.Feature: 4800 V three-phase operation enables direct integration with high-voltage feeders. Business Impact: Accurate capacitor sizing at 75 kVAR helps balance sizes for large loads and prevents over- or under-correction. Application: Ideal for HVAC systems, pumps, extrusion lines, and other load-heavy processes where voltage dips threaten performance. Practical note: The 75 kVAR rating aligns with common industrial PF correction targets, helping engineers meet tariff requirements without oversizing the bank.Feature: Three-fuse protection isolates faults and simplifies maintenance. Business Impact: Reduces risk of cascading faults and minimizes downtime during servicing. Application: Critical in control cabinets and outdoor enclosures where fast fault isolation matters. Industry context: In retrofit projects, three-fuse banks streamline integration with existing protective schemes and limit spare-part inventories.Feature: NEMA-rated enclosures (1, 3R, 12) plus a 14-gauge steel shell deliver rugged, weatherproof performance. Business Impact: Enables indoor and outdoor installations with durable protection against dust, moisture, and corrosion. Application: Outdoor substations or factory floors subject to dust, moisture, or temperature variations benefit from seal integrity and durable finish. Mounting versatility: Universal floor-mount flanges support straightforward retrofits and new builds.Feature: Viewing window and removable front cover support fast service access. Business Impact: Shortens maintenance cycles by enabling quick visual checks and component replacements. Application: Field service scenarios where downtime must be minimized and reliability is critical. Additional context: The enclosure design reduces knockouts, enabling flexible routing for top- or side-entry conduit runs and tidy installations.

FAQs
To install the 75483MVF3, de-energize the system and mount the unit on a level floor using the universal mounting flanges. Route conductors through the gasketed entries and observe the three-fuse protection scheme for safe operation. Remove the front cover only during maintenance, and ensure proper clearance for top or side-entry wiring per local codes.
Key specifications include a 4,800 V rating, three-phase configuration, a 75 kVAR reactive power rating, three-fuse protection, overall dimensions of approximately 20.42 in L, 34.44 in H, 20.26 in W, and a weight of about 70 lb. The enclosure options are NEMA 1, 3R, and 12, with Catalog Number 75483MVF3 and UPC 786685261485.
Yes. The unit features gasketed weatherproof seals and enclosure options (NEMA 1, 3R, 12) that enable indoor and outdoor installation. Its 14-gauge steel, baked-on enamel finish provides durability in dusty or moist environments, making it appropriate for outdoor substations and factory exterior installations when proper clearances are observed.
Warranty for the 75483MVF3 follows Eaton's policy 25-000: one year from the date of installation or eighteen months from shipment, whichever occurs first. Maintenance is facilitated by features such as a viewing window and removable front cover, enabling quick inspections and servicing with minimal downtime.
The 75 kVAR rating delivers effective PF correction for large motor loads and HVAC systems, reducing reactive power costs and improving voltage stability.
