This product has been developed specifically to soft start large single phase compressors and motors. It provides a dramatic reduction in the starting current but still provides full start torque. It will automatically adjust itself to cover the range of 1.75 to 7 hp. It is fully self-contained in a conveniently small, double insulated and flame retardant enclosure.
