Description
New Three-Phase Offering from Square D, DOE 2016 EX Exceed the efficiency levels. The DOE EX are terminals sized to handle wire ranges to match Square D circuit breakers, switches, panelboards, etc. Located to meet NEC bending radius and layout to simplifiy connections. The IZ Levels will allow for designing with the minimum AIC Panels available. The In-rush current limited to expand the Square D circuit breaker options at both 125 and 250% sizing. This DOE 2016 energy efficient transformer, is a 3 phase, 75 kVA, 60 Hz, with a natural convection cooling. The primary voltage of 480 V delta and a secondary voltage of 208Y/120 V. This trandformer has a rated Impedence withstand voltage of 10 kV and a temperature rise of 150 °C & 220 °C insulated. This product has an ambient air temperature of 40-40 °C and an average air temperature of 30 °C. It has an efficiency of 98.63 % and a load factor of 35 % and an ambient air temperature of 75.0 °C. With a peak withstand current of 3.71 kA and a tap loss of 142 & 2226. Dimensions for this product are 16.6 % (H), 851 mm (W), 697 mm (D) and a weight of 764 mm. This product complies to UL 1561, CSA C22.2 No 47 & NEMA ST-20.
