Are the KM1, KM2 and/or KM3 contactors included with ATS46 soft starters?
Open type Altistart 46 soft starters do not include the Line Isolation, Reversing and/or Shorting contactors. Factory built enclosed soft starter packages normally do include the shorting contactor and other contactors as specified on the original order. The ATS46 User guide shows sample wiring diagrams with the KM1, KM2 and KM3 designations. These drawings are samples to assist the installer in their own control wiring design.
