A reduced voltage starter reduces inrush line current and/or starting torque to a polyphase squirrel-cage induction motor. This is done by either reducing voltage applied to the motor during starting or by using only part of the motor windings during starting. GE can supply the three popular types of reduced voltage starters, each designed for specific applications requiring this type starting autotransformer, wye-delta and part-winding starters.

• Simple construction - 2 contactors, a timing relay and 2 overload relays
• Small size - starters are smaller than others in the reduced voltage category with comparable rating
• Closed transition - inherently provided
• Accurate adjustment - pneumatic time-delay contact permits accurate adjustment of maximum motor speeds on starting connections
