FAQs
Plan for a 225 kVA footprint within a suitable electrical room or substation enclosure. Ensure adequate clearance for ventilation, space for the WS35 Weathershield, and access for maintenance. The unit's 36.23 in length, 44.2 in width, and 75 in height along with a weight of 2492 lb necessitate proper mounting, rigging, and clearance on all sides.
It delivers 225 kVA at 60 Hz with a 480 V primary and 208Y/120 V secondary, plus taps at +2.5% / -2.5% for voltage regulation under load swings. The 115 °C rise rating supports hot environments, while UL Listed and NEMA TP-1 compliance ensure reliability and safety for mission-critical systems.
Yes. The transformer is UL Listed and NEMA TP-1 compliant, designed to meet industry safety and efficiency standards. It is also described as NEMA TP-1 efficient in catalog notes, with a low-noise profile aligned to 52 dB under typical full-load conditions.
Common applications include industrial power distribution in manufacturing environments, data centers, and machine control panels where stable voltage and reliable operation are essential. Its 480 V to 208Y/120 V output supports downstream equipment like drives, controllers, and electronics with tight voltage tolerance.
The 225 kVA rating supports scalable load growth, reducing the need for early replacements. With a 115 °C rise and aluminum windings, maintenance cycles are predictable, and the unit’s weather shield (WS35) and rugged frame reduce outdoor-corrosion risks. Warranty guidance indicates a one-year policy from installation or eighteen months from shipment, aiding lifecycle budgeting.
