FAQs
Yes. The unit is specified as a three-phase transformer with a 380 V primary (delta) and a 380Y/220 V secondary, designed for 50–60 Hz operation. Its 283M wiring and KT-13 design simplify integration with standard 380 V feeders, reducing rework in control panels and switchgear. Consider crane-capable handling due to its 1100 lb weight during on-site installation.
A K-Factor nonlinear transformer is engineered to manage harmonic-rich loads by reducing harmonic currents and improving power quality. It shines with non-linear equipment such as Variable Frequency Drives, power supplies, and other electronic loads prevalent in modern plants. Expect improved voltage regulation, reduced overheating, and longer life for downstream motors and drives when used in mid-to-large scale distribution.
Ideal for data centers, manufacturing floors with heavy motor control, and automated plants that require stable 380 V feeders and clean power distribution. Its KT-13 design, copper windings, and weatherized WS34 enclosure make it a strong fit for outdoor substations, control rooms, and critical process lines that demand reliability and precise voltage regulation.
Certification details for this model are managed by Eaton. The catalog notes Certifications: Contact Manufacturer, so regional requirements (for example CE, UL, or other standards) should be requested during purchase to ensure compliance with local electrical codes and project specifications.
Plan for periodic inspections of connections and insulation, especially at tap positions (+2.5% / -2.5%). The unit’s copper windings and electrostatic shielding reduce heat and EMI, contributing to lower maintenance cycles. Heavy-weight hardware requires proper lifting equipment; the 1-year warranty (or 18 months from shipment) offers initial protection while long-term energy efficiency and reduced downtime deliver favorable ROI in high-load facilities.
