FAQs
Installation should follow the product’s mounting dimensions (CT30E103 frame) and enclosure (C-C) guidelines. Ensure 480 V three-phase input, 208Y/120 V secondary connections (208Y/120 V), and 280B wiring practices. Verify clearance for ventilation and use appropriate lugs and protective devices. The unit’s tapped windings require accurate setting to +2.5% and -2.5% positions to maintain voltage within tolerance.
This transformer operates at 60 Hz with a 480 V primary and a 208Y/120 V secondary. It is designed for three-phase power distribution and supports voltage regulation via taps at +2.5% and -2.5%, helping maintain stable output under load variations.
Yes. It carries UL Recognized certification and complies with NEMA TP-1 efficiency standards. A Certified Test Report confirms standard production testing, providing traceability and energy-performance confidence for regulatory and procurement requirements.
Ideal for industrial and commercial power distribution where reliable 30 kVA capacity and voltage stability are needed. Its open-core ventilated design is well-suited to spaces with adequate airflow, data centers, manufacturing lines, and control panels requiring clean 208Y/120 V secondary power from a 480 V source.
Key factors include its compact dimensions (CT30E103 frame) and weight (approx. 251 lb) for easier handling, UL/TP-1 compliance minimizing regulatory risk, and a robust 150 °C rise rating within a 200 °C insulation system, which supports longer service intervals and reduced maintenance downtime in demanding environments.
