Industrical Control Transformer, 3PH 300KVA 480-208Y 120 provides a low and safe control voltage for the operation of electromagnetic devices, such as motor starters, contactors, solenoids, timers or other loads requiring above average voltage regulation when actuated. Replacing older general purpose transformers with our DOE 2016 compliant equipment will result in increased profitability from lower operating costs as well as a positive impact on the environment from a reduced carbon footprint.
