Feature → Business Impact → Application: Copper windings provide low resistance and high efficiency, reducing I2R losses and thermal buildup in demanding environments; this translates to cooler operation and longer service life for critical loads such as drives and controls in manufacturing lines. Application-wise, copper windings support reliable performance in three-phase 60 Hz systems with tight regulation, making it ideal for data centers and large equipment rooms. Feature → Business Impact → Application: 75 kVA rating matches typical mid-range distribution needs, enabling corridor-wide protection without over-sizing, which lowers capital and operating costs while maintaining headroom for load growth. Application: industrial facilities and PV integrations where future expansion is anticipated. Feature → Business Impact → Application: 480 V primary to 208Y/120 V secondary with 15° phase shift mitigates harmonic distortion while enabling clean, scalable feeds to sensitive electronics and PLCs. Application: control panels, panel boards, and utility interfaces. Feature → Business Impact → Application: Tap-changing capability with 2 at +2.5% and 4 at -2.5% FCAN/FCBN stabilizes voltage under fluctuating load, reducing nuisance trips and improving process stability. Application: sites with voltage sags or tight tolerances. Feature → Business Impact → Application: Dry-type design and frame 916A simplify installation in restricted spaces and factory environments; additional benefits include easier maintenance and safer containment. Application: plant floors and electrical rooms requiring fire-safe, maintenance-friendly transformers. Feature → Business Impact → Application: Electrostatically shielded construction and WS19 weather shield extend life in harsh environments and outdoor installations, reducing maintenance cycles and unexpected downtime. Application: outdoor equipment enclosures and coastal or industrial sites.

FAQs
This transformer is designed to attenuate harmonic currents in three-phase networks, using copper windings and a dry-type construction to deliver stable voltage, reduced heating, and improved power quality for sensitive equipment.
It features a 480 V primary and a 208 Y/120 V secondary with a 75 kVA rating, enabling robust distribution to controls, drives, and auxiliary loads across industrial applications.
Yes. It is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficient cataloging, providing assurance for safety, performance, and energy efficiency in regulated environments.
The taps allow small adjustments to voltage under varying load conditions, helping to maintain tightly regulated voltages and reduce nuisance trips in environments where supply voltage can drift.
Ensure proper clearance for the 23.42 in depth, secure mounting for the 855 lb unit, and consider enclosure or outdoor mounting options with the WS19 weather shield. Copper windings imply good conductivity but require adequate cooling and ventilation in tight spaces.
