FAQs
Plan for a 480 V primary and 208Y/120 V secondary, with space for ventilated cooling and adequate clearance. Ensure taps are accessible for ±2.5% adjustments and verify enclosure protection meets site requirements. The transformer can be integrated with standard three-phase breakers and Eaton Flex Center configurations to streamline installation.
This unit is a 75 kVA transformer with a 480 V primary and 208Y/120 V secondary. It features taps at +2.5% and -2.5%, copper windings, and a KT-13 nonlinear design suitable for harmonic-rich loads. Cooling is ventilated with a high insulation rating (150°C rise / 200°C insulation system).
Certification details for this exact model are provided by the manufacturer. Eaton notes certifications via documentation and regional approvals upon request. In practice, industrial transformers commonly seek CE and UL marks; confirm specific certifications with Eaton for your project location.
Applications include automation cells, motor drives, data centers, and manufacturing lines where power quality and harmonic mitigation are critical. The 75 kVA rating supports medium-load centers while the 480 V to 208Y/120 V secondary configuration suits widespread equipment pools and panel boards.
Copper windings and robust insulation support long life and reliable operation under high-duty cycles. Ventilated cooling reduces thermal stress during peak loads, lowering maintenance needs and extending service intervals in demanding industrial environments.
