Three-Phase Isolation Transformer – 300 kVA (Aluminum Windings, K-Factor 4, Dyn11)

is a robust and efficient isolation transformer designed for dependable performance in demanding industrial environments. Its aluminum windings, combined with a K-Factor 4 rating, effectively reduce harmonic currents, while the Dyn11 vector group provides balanced three-phase power and minimal leakage. Rated at 300 kVA with an efficiency exceeding 96%, this transformer is engineered for continuous operation in ambient temperatures up to 50 °C. Users can select the IP00 open-frame configuration for controlled settings or the IP23 enclosed version for enhanced protection against dust and moisture. Meeting the requirements of IEC 61558-1, IEC 61558-2-4, and IEC 60076-1 standards, it guarantees essential galvanic isolation and adheres to strict safety regulations. 🔧 Specifications:
