FAQs
For a new control panel, ensure a footprint that accommodates the 23.42 in length, 46.58 in height, and 28.22 in width. Use a ventilated-free, totally enclosed non-ventilated housing to minimize dust ingress and simplify mounting. Verify 380 V three-phase supply wiring, proper clearance for air flow, and compatible frame 916AN mounting. The copper windings and DT-3 design support reliable operation within a 60 Hz network, with the 75 kVA rating providing scalable power for expanding panels.
Key specs include 75 kVA three-phase power, 60 Hz frequency, primary and secondary voltages both at 380 V, and a 150 °C rise insulation rating. Taps are available at 2 at +2.5% FCAN and 4 at -2.5% FCBN to accommodate voltage variations. Copper windings improve electrical efficiency, while a frame 916AN supports a robust installation. These factors collectively influence transformer sizing, enclosure design, and overall system efficiency.
Yes. It is a 380 V primary and 380 V secondary, three-phase dry-type transformer designed for industrial power distribution. The totally enclosed non-ventilated construction protects internal windings from dust and moisture, while the 60 Hz specification ensures compatibility with standard U.S. industrial electrical systems. The 75 kVA rating supports mid-range load distribution, making it a versatile choice for multiple feeders in a single plant.
The V38M63T75CUNV carries UL Listed certification, confirming compliance with safety and electrical standards for industrial transformers. This certification supports code-based installation in facilities and simplifies supplier qualification for procurement teams seeking verified safety performance. If CE or IP ratings are required for a specific market, confirm regional compliance separately, as UL is the documented certification in the provided data.
Maintenance benefits stem from the totally enclosed design, reducing dust ingress and cooling needs, which lowers routine cleaning and filter changes. The dry-type construction with copper windings and a 150 °C rise rating supports durable insulation and reliable operation under elevated ambient temperatures, contributing to longer service life and reduced replacement costs. The 75 kVA rating provides scalable power without frequent transformer swaps, supporting a lower total cost of ownership and faster ROI in growing production lines.
