Power Connection with Star-Delta Connection Kits
Overview
Star-Delta connection kits can be used for the power connections of the three contactors. These connection kits can be used for contactors with or without cable memory. Check the below table for selection of suitable star-delta connection kits.
Star-delta connection kits are made of three coupling bars:
-
the line-delta coupling bar, to couple the line and delta contactors with identical ratings
-
the star-delta coupling bar, to couple the star and delta contactors.
-
the star coupling bar to couple the motor stator windings.
The table below provides the list of the star-delta connection kits:
