Description
ES5HB50S Emerson Sola-HD Low Temperatue Rise Ventilated Distribution Transformer, 50kVA, 240 x 480 Volt Primary, 120/240 Secondary, 60 HZ, 80 degree C rise, UL Listed E25872, UL 1561, Primary Amps 208/104, Secondary Amps 416/208
Low Temperature Rise Transformers
Hevi-Duty low temperature rise transformers feature a 220°C insulation system and temperature rise of only 80°C or 115°C under full nameplate load. The result is 13-21% lower operating losses than conventional 150° rise units. Reduction in temperature rise increases reliability.
The 35oC thermal reserve on 115°C rise units and 70°C reserve on 80°C rise units definitely mean lower operating costs. The extra benefit is being able to operate either of these transformers as a 150°C rise unit and have an overload capability of 15-30% without compromising normal life expectancy.
Low temperature rise transformers are designed for any critical application requiring extra overload capability, lower than average total losses and/or cooler operating temperatures. All are available with either a 115°C or 80°C thermal rise and a fully coordinated class 220°C insulation system.
