Feature: Copper windings and electrostatic shielding minimize copper loss and electrical noise, improving overall efficiency. Business impact: lowers operating costs and extends equipment life under steady-state and peak harmonic loads. Application: ideal for 480 V to 208Y/120 V distribution in data centers and manufacturing floors. Feature: 300 kVA rating with 60 Hz three-phase operation and a 15° phase shift delivers robust performance for power-hungry systems. Business impact: supports non-linear loads and harmonic mitigation without oversized equipment. Application: motor drives, PV systems, and office/commercial electrical stacks that demand reliable power quality. Feature: Tap changes of 2 at +2.5% and 4 at -2.5% provide voltage regulation to maintain downstream voltage during feeder or source fluctuations. Business impact: reduces voltage-related downtime and equipment stress. Application: installations with variable supply or long feeders where voltage swings are common. Feature: Copper-windings construction, frame 920X, and substantial physical footprint (36.23 in D × 75 in H × 44.2 in W, ~4377 lb) enable durable, shop-floor friendly installation. Business impact: predictable service intervals and easier handling with standard rigging. Application: harsh environments or outdoor spaces where reliability is critical. Feature: Electrostatically shielded design and WS35 weather shield option enhance protection against dust, moisture, and electrical noise. Business impact: reduces maintenance cycles and extends mean time between failures. Application: outdoor or semi-outdoor dry-type distribution in harsh facilities, including data centers and manufacturing plants.
