75 kVA three-phase rating with 480 V primary and 208Y/120 V secondary provides scalable power distribution and minimizes voltage drop across panels, improving panel reliability and equipment uptime. This direct mapping supports fewer devices and easier wiring, reducing installation complexity and lifecycle costs. Ideal for automation racks and panel boards in manufacturing environments. Open core-coil ventilated design delivers superior cooling and a higher temperature tolerance, enabling longer service life in hot plant rooms. Business impact is lower maintenance intervals and fewer derates during peak production. Application includes compact switchgear areas and control panels where airflow is constrained. Tap settings of 2 at +2.5% and 4 at -2.5% provide voltage regulation to accommodate supply variations without oversizing equipment. Resulting benefits include reduced voltage stress on downstream equipment and improved regulator response. This is essential for sensitive automation modules and distributed control systems in variable-power facilities. Aluminum coil windings and a rugged 914C frame balance durability with weight management, easing handling and mounting. The weight (about 491 lb) informs lifting plans and space planning, while corrosion resistance translates to longer service life in harsh environments. Perfect for panel-mounted installations in standard industrial spaces. Regulatory compliance is clear with NEMA TP-1 efficiency and UL Recognized certifications, complemented by a 150°C rise rating. Warranty coverage (one year from installation or 18 months from shipment) reduces risk and simplifies procurement. These factors support compliant, risk-aware deployments in critical infrastructure projects. In practice, the V48M28T75EEZZ aligns with modern automation demands by enabling a single, centralized transformer for multiple end loads, simplifying maintenance, and improving energy management. The 75 kVA capacity supports future expansion, while compatibility with 480 V systems ensures seamless integration with existing electrical distributions in factories and data centers.

FAQs
The V48M28T75EEZZ is a three-phase, dry-type transformer designed for 480 V primary feeding 208Y/120 V secondary in control panels. Mount it in standard rack or panel spaces, orient for proper airflow, and connect the primary windings to a 480 V three-phase supply. Use the taps at +2.5% and -2.5% for voltage regulation and follow UL and NEMA TP-1 guidelines during installation.
Key specs include a 75 kVA rating, 60 Hz operation, primary 480 V, secondary 208Y/120 V, aluminum windings, a 914C frame, taps at +2.5% and -2.5%, and a 150°C rise with 200°C insulation. These parameters ensure reliable power conversion for automation loads, enable voltage regulation under supply variation, and support efficient operation in typical industrial environments.
Yes. With 75 kVA capacity and 480 V to 208Y/120 V output, the V48M28T75EEZZ fits motor control centers and automation panels. The open-core ventilated design improves cooling, reducing thermal stress on downstream devices. UL Recognized and NEMA TP-1 compliant, it integrates with standard MCC architectures while maintaining regulatory compliance.
This unit is UL Recognized and NEMA TP-1 compliant, with a 150°C rise rating for tough ambient conditions. These certifications reduce regulatory risk, support safe operation in industrial facilities, and simplify supplier qualification. The warranty (one year from installation or 18 months from shipment) further mitigates downtime risk and aligns with procurement policies.
The V48M28T75EEZZ consolidates transformer needs to a single 75 kVA asset, reducing the footprint and interconnects in panels, which lowers installation time and maintenance complexity. Expect improved uptime due to enhanced cooling and robust construction. Regular checks for insulation, connection torque, and venting behavior will sustain performance and maximize long-term energy management benefits.
