Copper windings reduce copper losses and improve thermal response, delivering higher overall efficiency in continuous operation and better short-circuit protection for critical loads. This translates to measurable energy savings and cooler operation in equipment rooms and distribution cabinets, supporting robust performance in data centers and manufacturing lines. The 225 kVA three-phase rating at 60 Hz provides headroom for load growth, minimizing transformer swaps and installation time. Tap settings at +5% and -5% allow voltage adaptation to site swings, improving voltage regulation and equipment longevity in environments with fluctuating supply. Electrostatic shielding reduces stray capacitance and EMI, lowering interference with controls and sensors in automation cabinets. The WS35 weather shield and rugged frame 919 enable reliable outdoor or harsh indoor installations, while UL Listed and NEMA TP-1 efficient specifications simplify compliance and procurement for OEMs and end users. Copper windings, high-temperature rating, and precise voltage regulation combine to reduce operating costs and extend service life in industrial plants.
