AET Motor Starting Auto-Transformers









AET ZAT series Motor Starting Auto Transformer with fixed tapings are used in Auto Transformer
type of starters to reduce the voltage across the motor terminals while starting. This reduced
voltage limits the in rush current and lessen the strain on driven machinery while starting the
motor. For the same value of line current drawn during the starting period motors with auto
transformer type starters deliver the maximum starting torque when compared to other type of
starters.
