The CV29M47T75EE delivers 75 kVA of three-phase power at 60 Hz, providing ample headroom for mid-sized industrial loads and reducing voltage fluctuations along feeders. This improves motor performance and process stability, translating to fewer trips and higher overall productivity in manufacturing lines. The voltage taps (+2.5% and -2.5%) enable precise compensation for line drop and load variations, which minimizes equipment stress and extends service life for critical pumps and drives. Its ventilated design enhances cooling under heavy loads, improving reliability during peak production cycles and in warm plant environments. A durable NEMA 2 enclosure and Frame 914F simplify indoor installation, protect components from dust, and ease mounting in standard electrical rooms. Certifications from CSA and UL streamline compliance audits and safety approvals while the 75 kVA rating aligns with typical distribution needs across facilities, reducing the number of transformers required on multi-branch systems. This unit’s 208 V to 480Y/277 V configuration supports existing switchgear and downstream equipment, allowing straightforward integration with minimal rework and faster time-to-operational status. In practice, plant engineers gain a dependable, regulatory-compliant solution that delivers predictable voltage, reduced maintenance, and a clear path to ROI.

FAQs
Install indoors in a dry environment using the NEMA 2 enclosure. Provide adequate clearance for cooling and wiring access, secure the 914F frame, and connect primary 208 V and secondary 480Y/277 V circuits per Eaton installation guidelines. Use properly rated cables, torque specifications, and ensure proper grounding for safe operation.
This is a 75 kVA 3-phase transformer operating at 60 Hz with a primary of 208 V and a secondary of 480Y/277 V. It features voltage taps at +2.5% and -2.5% for fine-tuning, a voltage rise rating of 150 °C, insulation rated to 200 °C, and a weight of 663 lb. The DT-3 design supports robust industrial distribution.
Yes. It is designed for general purpose 3-phase power distribution in manufacturing, processing, and facilities requiring reliable voltage transformation. Its 75 kVA rating, ventilated cooling, and indoor NEMA 2 enclosure make it ideal for plants, data centers, and equipment rooms that demand stable 480 V distribution from 208 V sources.
The unit is CSA Certified and UL Listed, signaling compliance with essential safety and performance standards for industrial electrical equipment. These certifications simplify procurement, support regulatory audits, and reduce risk when qualifying power distribution assets for harsh or safety-critical plant environments.
Maintenance requirements are typical for industrial transformers: routine inspections of insulation, connections, and enclosure integrity during electrical room audits. The warranty covers one year from installation or 18 months from shipment, whichever comes first, providing protection against manufacturing defects and supporting a favorable total cost of ownership.
