Selling Policy 25-000 - Distribution and Control Products and Services
DOE 2016 Efficient compliance and UL Listed rating ensure regulatory alignment and lower operating costs for dry-type distribution transformers. In practice, these certifications reduce compliance risk and simplify procurement for plant facilities and data centers. K-Factor 13 design supports nonlinear loads by reducing overheating and improving voltage stability. This is essential for facilities with VFDs and power supplies, enabling reliable operation of automation equipment. Capacity and voltages: 150 kVA, three-phase, 208 V primary and 208Y/120 V secondary, 60 Hz. The 1 at +5%, 2 at -5% taps enable on-site voltage tuning to match loading conditions across the plant. Rugged construction like aluminum windings, 220 °C insulation, FR945 frame, and NEMA 2 enclosure deliver durability in indoor environments. This combination supports longer service life while keeping installation lightweight and manageable. Protection and compatibility features such as WS62 weather shield, 325 A wiring connection, and floor or wall mounting facilitate quick integration into existing electrical rooms. These design choices reduce field modifications and optimize space usage on factory floors.
