Dongan 63-LTH309SH 9KVA 480 DELTA-208Y/120 GP TRANSFORMER

Series LTF and LTH Transformers are three phase, low temperature rise, air cooled, general purpose distribution transformers. These transformers feature either an 80C temperature rise or a 115C temperature rise with a 220C insulation system and all are shielded. They are designed for applications where cool operating temperatures or thermal overload requirements are demanded. Thermal overload capability of 15% to 30% is built-in because these units are designed to operate with a maximum rise of 150C. This means units with an 80C rise have a 70C thermal reserve and units with a 115C rise have a 35C thermal reserve. These features insure a long life where moderate thermal or capacity overloads exist. NEMA Type 3R, indoor / outdoor enclosure.
